CASE REPORT
Regression of mitral regurgitation after cardiac resynchronization therapy in an adult with preserved left ventricular function and right ventricular pacing
Hospital Haut Leveque, Service Pr Clementy, University Victor Segalen, Avenue Magellan, Pessac, 33000 Bordeaux, France
We report the case of a 60-year-old patient with preserved ventricular function and no organic mitral leaflet disease implanted with a dual-chamber pacemaker. Right ventricular pacing induced a major ventricular dyssynchrony, a severe mitral regurgitation, and symptoms of congestive heart failure. Upgrading to a biventricular device was associated with a decrease in the symptoms, the ventricular dyssynchrony, and the mitral regurgitation.
Key Words: Biventricular pacing, Mitral regurgitation, Ventricular dyssynchrony
