Diastolic Valvular Regurgitation in Patient with Complete Atrio-ventricular Block

Abstract

Mitral regurgitation in conduction disorders is a rare feature of functional valve regurgitation. In patients with high-grade atrioventricular block, the onset of ventricular ejection may shift with atrial telesystole; in this case, the rise in left ventricular filling pressure after atrial systole, especially in the case of complete atrioventricular block leading to an inversion of the LA-LV gradient during the supraventricular relaxation phase and diastolic mitral insufficiency can gradually set in , as well as secondary tricuspid regurgitation Here we report the observation of a patient admitted for a complete atrioventricular block, with reversible mitral and tricuspid regurgitation after implantation of a pace maker.
