Restoring papillary muscle dimensions during restoration in dilated hearts.

Abstract:

:Left ventricular papillary muscle geometry is distorted in dilated non-ischemic hearts, and following anterior infarction caused by a wrap around left anterior descending artery occlusion. Loss of the apex creates a spherical left ventricular (LV) chamber, and subsequent dilation causes secondary mitral insufficiency by stretching the annulus, altering tethering of the chords and widening the dimension between the bases of papillary muscles to impair leaflet coaptation. This report will describe an intraventricular way to narrow the widened inter papillary muscle distance toward normal.
