A comparative study between ascending and descending aortic perfusion in left ventricular assist device

Abstract

Hemodynamic effectiveness of two different perfusion mode in LVAD was evaluated against acute left ventricular failure in swine. Renal blood flow was increased in descending aortic perfusion mode, but coronary sinus flow and endocardial viability ratio were increased more markedly in ascending aortic perfusion mode. These results suggested ascending mode appeared to be more promising method of assisting the failing heart complicated with acute myocardial infarction.
