Ten-year experience with mitral valve replacement in the elderly.

abstract：:Vasodilators facilitate ventricular emptying by affording earlier onset of left ventricular (LV) ejection and increased stroke volume with achievement of a reduced end-systolic pressure and volume. Agents with positive inotropic properties increase stroke volume by shifting the end-systolic pressure-volume curve to th...
