Cardiac dynamics during left ventricular assist

-Recovery process from the left ventricular failure-

Abstract

Bulk and regional left ventricular mechanics on the recovery process from the induced myocardial infarction by the left ventricular assist were studied on goats by in vivo chronic experiments using implantable miniature sonomicrometers. The regional work in the ischemic area and the left ventricular bulk work increased gradually, which suggested that the left ventricular assist reduces the infarcted area and recovers the myocardial function.
