History of Edwards Lifesciences
Edwards Lifesciences’ roots date to 1958, when Miles “Lowell” Edwards set out to build the first artificial heart. Edwards was a 60-year-old, recently retired engineer holding 63 patents in an array of industries, with an entrepreneurial spirit and dreams of helping patients with heart disease. His fascination with healing the heart was sparked in his teens, when he suffered through two bouts of rheumatic fever, which can scar heart valves and eventually cause the organ to fail.
With a background in hydraulics and fuel pump operations, Edwards believed the human heart could be mechanized. However, when he presented the concept to Dr. Albert Starr, a young surgeon at the University of Oregon Medical School, the idea was met with hesitation. Instead, Starr encouraged Edwards to focus first on developing an artificial heart valve, for which there was an immediate need. After only two years, the first Starr-Edwards mitral valve- which is not longer available for sale – was designed, developed, tested, and successfully placed in a patient. Newspapers around the world reported on what they termed a “miraculous” heart surgery. This innovation spawned a company, Edwards Laboratories, which set up shop in Santa Ana, Calif. — not far from where Edwards Lifesciences’ global headquarters is located today.
Edwards Lifesciences’ heart valve expertise has led to the development of one of the most exciting opportunities in the cardiovascular field – transcatheter heart valve replacement. The specially-designed valve and delivery system* is being evaluated in clinical studies in which high-risk patients receive a valve replacement without traditional open-heart surgery and while their heart continues to beat. Clinicians replace a patient’s aortic valve via a catheter inserted into a small incision in either the leg or between the ribs. Edwards Lifesciences’ leadership in transcatheter heart valve replacement includes a commitment to rigorous scientific study of the procedure and to extensive clinician training and education. Consistent with this effort to explore less invasive surgery, the company is committed to providing tools for minimally invasive cardiac surgery that allow cardiac surgeons to perform heart valve operations through small openings, or “ports,” in the spaces between the ribs.

In patients with severe aortic stenosis who were not suitable candidates for surgery, TAVI, as compared with standard therapy, significantly reduced the rates of death from any cause, the composite end point of death from any cause or repeat hospitalization, and cardiac symptoms, despite the higher incidence of major strokes and major vascular events.

Edwards Lifesciences Corp. (EW) won the backing of U.S. advisers for an expanded use of the company’s Sapien heart valve as an alternative to open-heart surgery. Edwards’ transcatheter aortic heart valve may soon have two indications: for aortic stenosis patients who are both inoperable and at high risk for surgery.
Smith, PARTNER trial’s principal investigator of Cohort A during the sponsor presentation, urged that the higher frequency of neurological events that occurred within the TAVR group should not be “trivialized” in either treatment group. Smith called aortic stenosis “one of the conditions we understand best in cardiovascular disease.” He called transcatheter aortic valve replacement (TAVR) a “miracle therapy,” and said that outcomes for the procedure will only continue to improve. And while most of the day’s conversation gave kudos to the PARTNER trial and its findings, concerns did focus on gender differences and neurological events.
Mark Hollmer explains that Edwards Lifesciences ($EW) scored a major win on Wednesday, successfully making its case before an FDA panel of experts that its Sapien transcatheter heart valve should be used in a broader class of patients. The agency’s Circulatory Systems Advisory Committee voted 11-0 (one panelist abstained) that the benefits outweighed any risks in using the valve for patients with severe aortic stenosis who are high-risk but could otherwise undergo surgery.
Investors reacted favorably, driving Edwards’ stock up more than 8% to $98.55 by midday on June 14. Bloomberg, MedPage Today, The Associated Press, CardiovascularBusiness and many others covered the day-long panel meeting and final vote. While the FDA doesn’t have to follow the panel’s recommendation, it usually does. Panel members also voted 12-0 that Sapien is effective and 10-2 that the valve is safe.
When the FDA comes out with its final decision is anyone’s guess, but Bloomberg predicts final action could come in October, based on the timeline for Sapien’s initial approval in 2011 (panel meeting in July; regulatory approval in November). Sapien initially gained FDA approval for patients with limited classes of stenosis who can’t have surgery.
To make its case during the 8-hour-plus hearing, Edwards Life Sciences relied on the “Cohort B” part of its pivotal PARTNER trial, which compared transcatheter aortic valve implantation (TAVI) with surgery. (“Cohort A” was used for the initial approval in November.) PARTNER recruited 699 high-risk older patients with severe aortic stenosis and randomly assigned them to TAVI (n=348) or surgery. About two-thirds of the TAVI patients underwent transfemoral procedures, where the device was threaded through the femoral artery, while 103 had transapical access procedures, where the device was inserted directly into the tip of the left ventricle of the heart.
Death rates were essentially the same at 1 year for the Sapien group and the control group. When divided up by type of valve implantation compared with matched surgery controls, the death rate for Sapien implanted via a transfemoral approach was 24.2% versus 26.8% for surgery; and for the transapical approach the 1-year mortality rate was 22.2% for the Sapien group and 26.4% for the open-heart surgery group. Although the death rate was very similar, TAVI patients had double the rate of stoke during the 30-day period following the procedure. With the transapical approach, there appeared to be an even greater increased risk for early stroke, which the panel chalked up to the fact that patients who received TAVI via transapical approach were sicker patients, so their outcomes were poorer than those who were implanted via a transfemoral approach.
The trial involved 699 older patients of high risk with severe aortic stenosis who were randomly assigned to the TAVI procedure or surgery. Among the findings: the death rate was similar for both, but patients who had transcatheter aortic valve implantation faced double the rate of stroke over the initial 30-day period after the surgery. That finding concerned both FDA scientists and panel members, though Edwards countered that stroke rates evened out after another year, Bloomberg notes. Regulators in advance of the hearing were also bothered by how the company chose patients and categorized them for the trial, arguing that it constituted bias to some degree, and potentially skewed the results.
Edwards wants to do a post-approval study to follow patients from the trial and also create a registry to enroll new patients. FDA staff members agree, and urged at least 5 years of follow-up for subjects from the trial.

Transcatheter Heart Valve Replacement Market: A Market of $2.5 Billion in the US
The market for transcatheter valves may total $2.5 billion in the U.S., said Jason Mills, a San Francisco-based analyst with Canaccord Adams Inc. The initial FDA approval of Sapien in November boosted Edwards’s sales 67 percent in the first quarter to $122 million, Michael Mussallem, the company’s chairman and chief executive officer, said in an April 24 earnings call.
The device is meant to treat aortic stenosis. The debilitating condition is caused by a narrowing valve that restricts the ability of blood to enter the aorta, the main artery that carries blood from the heart, according to the National Institutes of Health.
“A broader indication for high-risk patients would enable multidisciplinary heart teams to choose the approach best suited to their patients’ needs,” Mussallem said in a statement after the panel’s vote. “We look forward to working closely with the FDA during the review process, and thank the panel for their thoughtful analysis.”
The FDA may decide on approval in October if reviewers follow the same timeline they did when they cleared the valve for inoperable patients. Advisers met in July to consider the device for inoperable patients and approved it in November.
Another point of concern, as Bloomberg points out: FDA staff noted that patients treated with Sapien faced twice the stroke risk in the initial month after the implant procedure, compared to patients who had open-heart surgery instead.
The FDA wants the company to commit to a long-term follow up, post-approval study that tracks patients for at least 5 years to address its concerns. Edwards appears to be on the same page, having proposed a post-approval study that would follow patients from its pivotal trial, as well as a new patient registry, according to the story.
Edwards won a PMA for the Sapien device for inoperable patients with aortic stenosis, a hardening and narrowing of the aortic valve, in November 2011.* FDA reviewers said the arm of the study covering the high-risk patients may have been flawed by the inconsistencies.
“FDA notes that screening and subsequent enrollment practices were not homogenous. The large variation between the ratios of those screened to those enrolled may represent different selection criteria among sites,” according to documents released ahead of the meeting scheduled for Wednesday. “Enrollment practices related to identification of ‘inoperable’ and ‘high risk’ patients were not homogenous across sites.”
https://www.massdevice.com/news/fda-possible-selection-bias-issues-confound-edwards-sapien-study
FDA Panel
There was “no significant difference” in mortality between patients treated with surgery vs. treatment with the Sapien valve, according to the documents. But some patients who were slated for traditional open heart surgery were treated with the TAVI device, and vice-versa, making it difficult to evaluate the study’s endpoints.
“[T]he issue of [surgery] patients not receiving [surgery], [Sapien] patients receiving [surgery], and [surgery] patients undergoing concomitant operations makes evaluation of these endpoint results difficult,” according to the FDA reviewers. “Although the primary endpoint was met, issues related to potential selection bias confound the interpretation of these results.”
“We believe the Partner trial was well-designed and executed. We are proud of the efforts of the leading heart teams that supported this ground-breaking trial and what it means for patients,” an Edwards spokeswoman told MassDevice.com via email. “We are reserving further comment on this or related matters until the Advisory Committee scheduled for June 13.”
The FDA also wants the circulatory devices panel to consider better ways to construct future trials of similar devices and to come up with appropriate endpoints for a post-market surveillance study. The panel is scheduled to vote on whether the device is as safe and effective as surgery and whether its benefits outweigh its risks for the high-risk cohort.
Medicare to Cover Edwards’ Sapien Heart Valve
On May 2, 2012 Mark Hollmer reported that for medical device companies, gaining Medicare reimbursement for surgical procedures involving their implants can be a sort of financial holy grail. After all, an implant won’t be used much if the cost can’t be covered. Edwards Lifesciences ($EW) has reached that point now that the Centers for Medicare & Medicaid Services has agreed to pay for surgery involving its Sapien transcatheter heart valve. Ssince Sapien’s U.S. debut in November. As a result, sales should get a boost, Wells Fargo analyst Larry Biegelsen said, as quoted by Bloomberg in its coverage of the news.
Specifically, CMS approved reimbursement of transcatheter aortic valve replacement therapy when the device is used to treat symptomatic aortic valve stenosis. The coverage determination is flexible and authorizes current and future FDA approved indications, the company notes, as well as coverage for clinical studies.
About 300,000 U.S. patients suffer from deterioration of the aortic heart valve, which forces the heart to work harder to pump blood, often leading to heart failure, blood clots and sudden death. More than half of patients diagnosed with the condition, called aortic stenosis, die within two years, according to the FDA. Every year about 50,000 people in the U.S. undergo open-heart surgery to replace the valve, which involves sawing the breastbone in half, stopping the heart, cutting out the old valve and sewing a new one into place. Thousands of other patients are turned away, deemed too old or ill to survive the operation.
The Sapien valve is usually threaded through the femoral artery via a small incision in the leg, and then guided up to the heart via catheter. An alternate procedure inserts the valve through a small incision between the ribs. The valve is then wedged into the aortic opening by an inflatable balloon, replacing the natural heart valve. The device is made from cow tissue and polyester supported by a steel frame.
Analysts estimate as many as 70,000 to 100,000 patients per year could eventually receive the valve. In the most recent quarter Edwards reported Sapien sales of $121.5 million, with the U.S. contributing $41 million. For the full year Edwards expects sales of $530 million to $600 million.
http://www.mercurynews.com/business/ci_20850361/fda-panel-backs-broader-use-edwards-heart-valve
Two cardiac surgeons must independently evaluate the patient first, and hospitals offering the procedure must have an on-site heart valve surgery program, plus a cardiac catheterization lab or a lab/operating room hybrid with appropriate imaging systems. And as Bloomberg points out, the guidelines limit who can conduct the procedure to a multidisciplinary team of doctors that must include at least one heart surgeon and interventional cardiologist. And those experts must perform the surgery at least 20 times annually to remain certified.
CMS also requires the heart team and hospital to take part in a post-surgery clinical trial, a national registry that follows patients who have the procedure for at least one year. This study will look at variables including strokes, death, heart attacks, kidney injuries, any repeat procedures and overall quality of life.
Sapien, generated $41 million in sales during the first quarter, the first full quarter the device has been on the market.
June 13, 2012 – FDA panel votes in favor of Sapien valve. The FDA’s Circulatory System Devices Committee gave Edwards Lifesciences ($EW) a win Wednesday with a vote recommending the devicemaker’s Sapien transcatheter heart valve after an epic session. The panel voted 9-0–with one member abstaining–that the device’s benefits outweighed its risks, 7-3 in favor of its safety, and 9-1 for its effectiveness. The FDA will make a decision on the valve at a later date.
Earlier in the week, the FDA released a report showing the valve, which can be implanted without major surgery, significantly reduced death rates versus standard therapy in people with severe aortic stenosis. However, there was a higher incidence of major strokes and major vascular events seen in the group receiving the Sapien valve in a study.
Indeed, neurological events represented a major issue in the meeting, as heartwire notes, with several panel members pointing out that older, frail patients are far more concerned about strokes than death. Furthermore, mortality reduction with TAVI is, as the FDA terms it, impressive, but most treated patients die within two years. That said, panel members concluded that the benefits of transcatheter valve replacement in these frail patients offset the stroke risk.
“We are pleased with the panel’s strong recommendation for approval, and would like to thank them for their comprehensive and thoughtful review of the data presented from The PARTNER Trial. This represents another important step on the path to what we hope will lead to FDA approval of SAPIEN,” Michael Mussallem, Edwards’ chairman and CEO, says in a statement. “We would also like to thank the principal investigators and their heart teams at the PARTNER hospitals for their dedication to this clinical trial, and to their patients for participating in a study of a new therapy.”
Edwards has marketed Sapien in Europe since 2007 and could start selling it in the U.S. in Q4, 2012. Analysts note the worldwide market for heart valves could ultimately grow to $2 billion in annual sales, as the Orange County Business Journal reports.
http://www.fiercemedicaldevices.com/story/fda-panel-votes-favor-sapien-valve/2011-07-20
The valve SAPIEN is currently approved for patients who aren’t healthy enough to undergo the more invasive open-heart surgery, which has been used to replace the aortic valve for decades. On June 13, 2012 – the implant is approved for patients who are healthier, but still face serious risks from chest-opening surgery. Many such patients are in their 80s and have complicating medical factors like diabetes.
Irvine, Calif.-based Edwards plans to conduct two follow-up studies to evaluate long-term safety as well as differences in gender outcomes per FDA panel on June 13, 2012.
Decision Memo for Transcatheter Aortic Valve Replacement (TAVR) (CAG-00430N)
The Centers for Medicare & Medicaid Services (CMS) covers transcatheter aortic valve replacement (TAVR) under Coverage with Evidence Development (CED) with the following conditions described in
CONCLUSIONS
The Pay for Performance Philosophy at Edwards Lifesciences will support a substantial reward for the Chairman and CEO in 2012. His $5.8 Million in total compensation in 2011, occurred for a average of Five Year Total Stockholders Return of 301% while at the same time S&P delivered an anemic Five Year Total Stock Return of 89% per 2011 Edwards Most Recent Return: -11.8%, 42 percentile as reported in 2011 Edwards Annual Report. With the potential of EW symbol exceeding $100 per share in the second half of 2012, CEOs total compensation may move Edwards from the 36 percentile to the median in the Comparator Group selected for determination of Executive compensation at Edwards. . In the most recent quarter Edwards reported Sapien sales of $121.5 million, with the U.S. contributing $41 million. For the full year Edwards expects sales of $530 million to $600 million.
FDA’s broadening definition of patients eligible for TAVR to include other patients than the ones with aortic stenosis that can’t undergo open heart surgery, will have an immediate effect on the total cost that these procedures will bear by having the procedure been covered by Medicare and Medicaid. An increase in the Healthcare cost and its National burden is expected. Analysts estimate as many as 70,000 to 100,000 patients per year could eventually receive the valve.
The Procedure will have a major improvement in the quality of life of patients undergoing TAVR with a favorable impact on their longevity.
As an active echo tech, this is very useful information both from a clinical and market awareness perpective. Formerly I was a business analyst and people say what a difference in careers this is from echo. But, honestly, my background in market research and analytics seems to be more and more useful as these device development and ubiquity increase dramatically.

PUT IT IN CONTEXT OF CANCER CELL MOVEMENT
The contraction of skeletal muscle is triggered by nerve impulses, which stimulate the release of Ca2+ from the sarcoplasmic reticuluma specialized network of internal membranes, similar to the endoplasmic reticulum, that stores high concentrations of Ca2+ ions. The release of Ca2+ from the sarcoplasmic reticulum increases the concentration of Ca2+ in the cytosol from approximately 10-7 to 10-5 M. The increased Ca2+ concentration signals muscle contraction via the action of two accessory proteins bound to the actin filaments: tropomyosin and troponin (Figure 11.25). Tropomyosin is a fibrous protein that binds lengthwise along the groove of actin filaments. In striated muscle, each tropomyosin molecule is bound to troponin, which is a complex of three polypeptides: troponin C (Ca2+-binding), troponin I (inhibitory), and troponin T (tropomyosin-binding). When the concentration of Ca2+ is low, the complex of the troponins with tropomyosin blocks the interaction of actin and myosin, so the muscle does not contract. At high concentrations, Ca2+ binding to troponin C shifts the position of the complex, relieving this inhibition and allowing contraction to proceed.

Association of tropomyosin and troponins with actin filaments. (A) Tropomyosin binds lengthwise along actin filaments and, in striated muscle, is associated with a complex of three troponins: troponin I (TnI), troponin C (TnC), and troponin T (TnT). In (more ) Contractile Assemblies of Actin and Myosin in Nonmuscle Cells
Contractile assemblies of actin and myosin, resembling small-scale versions of muscle fibers, are present also in nonmuscle cells. As in muscle, the actin filaments in these contractile assemblies are interdigitated with bipolar filaments of myosin II, consisting of 15 to 20 myosin II molecules, which produce contraction by sliding the actin filaments relative to one another (Figure 11.26). The actin filaments in contractile bundles in nonmuscle cells are also associated with tropomyosin, which facilitates their interaction with myosin II, probably by competing with filamin for binding sites on actin.
Figure 11.26
Contractile assemblies in nonmuscle cells. Bipolar filaments of myosin II produce contraction by sliding actin filaments in opposite directions. Two examples of contractile assemblies in nonmuscle cells, stress fibers and adhesion belts, were discussed earlier with respect to attachment of the actin cytoskeleton to regions of cell-substrate and cell-cell contacts (see Figures 11.13 and 11.14). The contraction of stress fibers produces tension across the cell, allowing the cell to pull on a substrate (e.g., the extracellular matrix) to which it is anchored. The contraction of adhesion belts alters the shape of epithelial cell sheets: a process that is particularly important during embryonic development, when sheets of epithelial cells fold into structures such as tubes.
The most dramatic example of actin-myosin contraction in nonmuscle cells, however, is provided by cytokinesisthe division of a cell into two following mitosis (Figure 11.27). Toward the end of mitosis in animal cells, a contractile ring consisting of actin filaments and myosin II assembles just underneath the plasma membrane. Its contraction pulls the plasma membrane progressively inward, constricting the center of the cell and pinching it in two. Interestingly, the thickness of the contractile ring remains constant as it contracts, implying that actin filaments disassemble as contraction proceeds. The ring then disperses completely following cell division.

This is good. I don’t recall seeing it in the original comment. I am very aware of the actin myosin troponin connection in heart and in skeletal muscle, and I did know about the nonmuscle work. I won’t deal with it now, and I have been working with Aviral now online for 2 hours.
I have had a considerable background from way back in atomic orbital theory, physical chemistry, organic chemistry, and the equilibrium necessary for cations and anions. Despite the calcium role in contraction, I would not discount hypomagnesemia in having a disease role because of the intracellular-extracellular connection. The description you pasted reminds me also of a lecture given a few years ago by the Nobel Laureate that year on the mechanism of cell division.
PUT IT IN CONTEXT OF CANCER CELL MOVEMENT
The contraction of skeletal muscle is triggered by nerve impulses, which stimulate the release of Ca2+ from the sarcoplasmic reticuluma specialized network of internal membranes, similar to the endoplasmic reticulum, that stores high concentrations of Ca2+ ions. The release of Ca2+ from the sarcoplasmic reticulum increases the concentration of Ca2+ in the cytosol from approximately 10-7 to 10-5 M. The increased Ca2+ concentration signals muscle contraction via the action of two accessory proteins bound to the actin filaments: tropomyosin and troponin (Figure 11.25). Tropomyosin is a fibrous protein that binds lengthwise along the groove of actin filaments. In striated muscle, each tropomyosin molecule is bound to troponin, which is a complex of three polypeptides: troponin C (Ca2+-binding), troponin I (inhibitory), and troponin T (tropomyosin-binding). When the concentration of Ca2+ is low, the complex of the troponins with tropomyosin blocks the interaction of actin and myosin, so the muscle does not contract. At high concentrations, Ca2+ binding to troponin C shifts the position of the complex, relieving this inhibition and allowing contraction to proceed.
