	Introduction

 
The optimization of hemodynamic performance of aortic valve replacement substitutes is of paramount importance to surgeons, cardiologists, and industry as we gain more knowledge of the influence of exercise and the potential effects of inadequate left ventricular mass regression on survival. The authors have conducted a prospective hemodynamic evaluation of the St. Jude Medical Regent mechanical prosthesis designed to provide optimal hemodynamics. The study was conducted with 40 patients between March 2000 and July 2001.

The prosthesis design, to facilitate hemodynamic performance, is incompletely described in the article. The mechanical components of all St. Jude Medical prostheses are the same, except for rotatable configurations . . . [Full Text of this Article]
