Abstract:
A 73-year-old man with severe, symptomatic secondary mitral regurgitation (MR) underwent successful transcatheter mitral valve replacement using the Tendyne™ mitral valve system. The device was deployed from the left ventricular (LV) apex and secured in position by a tether attached to an epicardial pad. Three days postoperatively, the patient developed hemolytic anemia and a paravalvular leak (PVL) associated with indentation of the LV apex. Adjustment of the tether tension and placement of an epicardial disc under the pad resulted in reduction in the PVL, and resolution of the hemolytic anemia.

Mitral Valve Prolapse I: Introduction
Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
