VA hospitals favor mitral valve repair vs. replacement
Little is known about mitral valve surgical outcomes within the largest US federal health system -- the Veterans Administration Health System. At the 96th AATS Annual Meeting, data presented from 40 VA cardiac surgery centers reveal that although MV repair rates increased from 48 percent in 2001 to 63 percent in 2013, a wide variability exists in repair rates among medical centers. This is especially important because MV repair mortality rates were significantly lower in patients with primary degenerative disease. (2016-05-17)

Novel technique reduces obstruction risk in heart valve replacement
Researchers at the National, Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, have developed a novel technique that prevents the obstruction of blood flow, a common fatal complication of transcatheter mitral valve replacement (TMVR). The new method, called LAMPOON, may increase treatment options for high-risk patients previously ineligible for heart valve procedures. (2019-05-20)

Updated AATS guidelines help cardiovascular surgeons navigate the challenges of managing ischemic mitral regurgitation
How best to treat IMR is controversial, in part, because of the fragility and complexity of the patients, difficulty of grading IMR, the variety of medical and surgical options, and lack of long-term quality studies. Noting that other guidelines generally do not focus on optimal surgical approaches to IMR, the AATS enlisted a group of experts to create a consensus document to provide clinicians with their recommendations based on their opinions and the best available evidence. (2017-04-17)

Circulating endothelial microparticles lead to heart valve disease
Under normal physiological conditions, low levels of microparticles are continually being shed into the blood from the endothelium - the cells that line the inside of blood vessels and some organs - and appear to cause no problems. But during some diseases, the level of endothelium-derived microparticles circulating in the blood rises. (2006-04-04)

Does open heart surgery affect cognitive abilities?
Understanding how heart valve surgery may affect your cognition is important for older adults. To learn more, researchers reviewed studies to see how patients' cognition changed before and after heart valve surgery. They also looked at whether surgeries on two types of heart valves, the mitral or the aortic, were associated with better or worse outcomes. Their study was published in the Journal of the American Geriatrics Society. (2018-10-12)

Echocardiograms may help with patient selection for transcatheter mitral valve repair
Clinicians should use echocardiography, an ultrasound that shows the heart's structure and function, when determining whether patients with heart failure and a leaking heart valve are likely to benefit from valve repair, according to research presented at the American College of Cardiology's 68th Annual Scientific Session. (2019-03-18)

Heart valve ring reverses damage from congestive heart failure, easing symptoms
A new heart valve ring appears to help congestive heart failure patients regain lost heart function, reversing the disease's effects on heart structure in two ways and easing their disabling symptoms. The ring reduced the leakage of blood back through the mitral valve, which leads to the heart's main pumping chamber. But it also changed the shape of that chamber, called the left ventricle, helping its muscular walls contract and pump blood better. (2005-04-13)

Older patients with atrial fibrillation at greater risk for post-op tricuspid regurgitation after mitral valve repair
Tricuspid regurgitation occurs when the heart's tricuspid valve leaks, allowing blood to flow back from the right ventricle to the right atrium. TR can be secondary to disorders of left-sided heart valves (mitral or aortic). Investigators present the results of a long-term study of patients who underwent mitral valve (MV) repair. They found that although newly developed TR after MV repair was rare, the risk could increase in older patients with atrial fibrillation and impaired heart function. (2016-05-16)

First in vitro study of tricuspid valve mechanics uncovers causes for leakage
An estimated 1.6 million Americans suffer moderate to severe leakage through their heart's tricuspid valve, but what causes the problem is not well understood. A new study found that either dilating the tricuspid valve opening or displacing the papillary muscles that control its operation can cause the valve to leak. A combination of the two actions can increase the severity of the leakage, which is called tricuspid regurgitation. (2011-08-09)

New technology offers alternative to open heart surgery
A new method of treating mitral regurgitation (MR), the leaking of blood through the mitral valve into the heart chamber, provides a less-invasive alternative to open heart surgery. A study published in Journal of Interventional Cardiology found that a variety of advances have allowed for the potential treatment of MR through various catheter techniques, similar to angioplasty. While over 50,000 mitral valve surgical procedures are performed annually, open surgery is an undesirable option, especially for high-risk patients. (2006-11-16)

Study offers less complex, minimally invasive procedure to treat heart valve leak
Cardiac experts at Rush University Medical Center are studying a new, minimally invasive procedure to treat leaky heart valves. Instead of open heart surgery, patients will undergo a less complex catheter-based procedure to treat mitral regurgitation, a serious heart disorder where blood leaks backwards toward the lungs with each heart beat. (2009-09-29)

New way to fix leaking mitral heart valves safe in initial testing
A novel method to seal leaking heart valves was proven safe in its first use in heart failure patients. If effective in larger trials, the PTMA system could significantly reduce the life-threatening risks associated with surgical repair of the mitral valve. (2009-06-23)

Total hospital cost of robotic or conventional open-chest mitral valve repair surgery is similar
The total hospital cost of mitral valve repair surgery -- from the time a patient is admitted to the hospital until release -- is similar, whether performed through small port incisions using robotic equipment or via the conventional open-chest method, a Mayo Clinic study of 370 patients found. Importantly, robotic surgeries were just as safe as conventional open procedures, but patients who underwent robotic mitral valve repair recovered more rapidly and returned home earlier than patients who had open-chest surgery, the study found. (2013-10-01)
