Timing of Surgery for Asymptomatic Primary Mitral Regurgitation:
Possible Value of Early, Serial Measurements of Left Ventricular Sphericity
Alfred Stanley,

Abstract:Abstract::
Asymptomatic primary mitral regurgitation due to myxomatous degeneration of the
mitral valve leaflets may remain so for long periods, even as left ventricular function progresses
to a decompensated stage. During the early compensated stage, the ventricle’s initial response to
the volume overload is an asymmetric increase in the diastolic short axis dimension, accomplished
by a diastolic shift of the interventricular septum into the right ventricular cavity, creating
a more spherical left ventricular… Show more
