More Heart Valves Should Be Repaired, Rather Than Replaced

Degenerative mitral valve disease without symptoms calls for a valve repair procedure, but too often the valve is replaced instead.  Those are the findings of a study conducted by David H. Adams, MD, and colleagues at Mount Sinai School of Medicine and published in the August 16 edition of The European Heart Journal. 

The study focused on patients with mitral valve regurgitation, in which the valve does not close tightly enough and blood flows backward in the heart. This is the most common form of heart valve disease. 

Surgical intervention often is needed when symptoms of mitral valve regurgitation appear. These include a decline in function or enlargement of the heart’s left ventricle, or the development of atrial fibrillation, characterized by a rapid, irregular heartbeat, or severe hypertension in the pulmonary arteries that can increase the workload on the right side of the heart. Patients with mitral valve regurgitation may experience fatigue and shortness of breath.

Compared with valve replacement, mitral valve repair is associated with better long-term survival rates and preservation of heart function and fewer complications such as infection and stroke. Valve repair also does not require long-term use of blood thinners.    

Cardiologists should become more familiar with treatment guidelines in order to make more appropriate surgical referrals, the Mount Sinai researchers concluded.

A drug-eluting stent (DES), a mesh tube that can help prop open arteries after they are widened by balloon angioplasty, is more helpful than a bare-metal stent in preventing death and heart attacks for up to five years, according to a new study. Drug-eluting stents release...
