Common heart condition linked to sudden death
A University of Adelaide-led team of researchers has found a link between sudden cardiac death (when the heart suddenly stops beating) and a common heart condition known as mitral valve prolapse that affects around 12 in every 1000 people worldwide. (2018-09-25)

University of Virginia Health System tests new device for mitral valve disease
For years, the standard of care for mitral valve leakage has been open-heart surgery with the patient on a bypass machine. Now, heart patients at the UVa Health System have a new, less invasive, option to get a leaky valve fixed. The UVa Health System is part of a national, randomized clinical trial of a tiny, permanent, implanted device made out of titanium called the MitraClip, which 'clips' the leaky halves of the mitral valve together without major surgery.

Study discovers serious deficiencies in 'apparently normal' heart valves
Surprising findings in the Journal of the American College of Cardiology show the basic biochemical composition of heart valves in patients with congestive heart failure are markedly different than those with healthy hearts. This may explain the mixed success of surgery to repair valve dysfunction in these patients. The new study suggests that changes in the valves themselves may contribute to the problem of mitral regurgitation, or failure of the valves to close properly. (2005-01-24)

In a comparison of mechanical prosthetic vs bioprosthetic mitral valves among patients 50 to 69 years of age undergoing mitral valve replacement, there was no significant difference in survival at 15 years, although there were differences in risk of reoperation, bleeding and stroke, according to a study in the April 14 issue of JAMA. (2015-04-14)

Women with mitral valve prolapse are treated less aggressively than men and may be at high risk
Disturbing evidence of higher mortality and lower surgery rates in women versus men with mitral valve prolapse and severe leakage may be related to the complexity of evaluating the condition's severity in women, according to findings of a Mayo Clinic study published this month in the Annals of Internal Medicine. (2008-12-01)

Study details safe, effective, minimally invasive mitral valve repair
Minimally invasive, patient-friendly surgical techniques are widespread, but there is little data to prompt the routine use of these techniques in mitral valve surgery, especially in cases where the valve can be repaired. After a six-year study, surgeons at the University of Maryland Medical Center in Baltimore conclude that minimally invasive mitral valve repair techniques, through only a two-inch incision in the right side of the chest, are safe, durable and effective. (2009-09-28)

Comprehensive evaluation of mitral valve-in-valve and valve-in-ring
Mitral valve-in-valve (ViV) and valve-in-ring (ViR) are alternatives to surgical reoperation in patients with recurrent mitral valve failure after previous surgical valve repair or replacement.

Half of eligible patients not getting mitral valve surgery, U-M study shows
Repairing a leaking mitral valve is safer than ever, but half of eligible patients are not getting the heart surgery, according to a new study by the University of Michigan Cardiovascular Center. The longer the leak continues the more likely there will be permanent damage to the heart. But fears about surgical risk and lack of awareness -- even by physicians -- about guidelines for treating mitral regurgitation lead to a lack of referrals. (2009-09-11)

Boston Children's surgeons pilot expandable prosthetic valves for congenital heart disease
Surgeons at Boston Children's Hospital have successfully implanted a modified version of an expandable prosthetic heart valve in several children with mitral valve disease. Unlike traditional prosthetic valves that have a fixed diameter, the expandable valve can be enlarged as a child grows, thus potentially avoiding the repeat valve replacement surgeries that are commonly required in a growing child. The new paradigm of expandable mitral valve replacement has potential to revolutionize care for infants and children with complex mitral valve disease. (2012-10-03)
