In vivo hemodynamic characteristics of porcine stentless aortic valves.
The objective of this study was to elucidate the relationship of aortic pressure gradient (mPG) and effective orifice area (EOA) with mean systolic flow rate of left ventricle in patients who received a stentless aortic valve. Two hundred thirteen patients (age: 73 +/- 6 years, 123 men and 90 women) who received a Freestyle stentless valve in subcoronary position for aortic valve diseases were studied. EOA, mPG, and systolic aortic flow rate were determined by Doppler echocardiography at 1 an...Expand abstract
