An anti-obesity drug Fen-Phen contained Fenfluramine, also known as Pondimin was shown to cause mitral valve disease and cardiac fibrosis. Studies showed that this drug caused thickening of the valve leaflets and chordae tendinae. The drug was withdrawn from US market in 1997.

Chronic mitral regurgitation may be asymptomatic in the compensated phase, when the left ventricle hypertrophies and the left atrial size increases proportionately to maintain the cardiac output. When the patient progresses to the decompensated phase, there may be left ventricular dysfunction. He/She may have symptoms of heart failure. Pulmonary congestion increases.

Methods for Mitral Valve Repair: Annuloplasty:In annuloplasty an artificial ring is placed around the annulus of the valve.This ring reinforces the annulus and restores the valve to its normal shape and size. Balloon Valvuloplasty:Balloon valvuloplasty is performed using a catheter, i.e. a very thin flexible tube which can be inserted into the body, with a balloon at the end. The balloon is put inside the valve and is expanded thus stretching the valve and bringing it back to its normal size. For more info: heart-consult.com/articles
