Abstract:
From July 1991 to June 2002,80 patients undergoing 19 mm aorta mechanical prosthetic valve replacement and 80 patients undergoing ≥ 21-mm valve replacement were enrolled. There was a significant difference in left ventricular wall thickness,mass index,and pressure gradients in 19-mm valve replacement (P 0.05). The difference of left ventricular wall thickness,mass index,and pressure gradients was lower in group with effective orifice area index (EOAI) 0.75 cm2/m2 (P 0.05). Patients with 19-mm prosthetic aortic valves can experience a satisfactory improvement and intermediate-term survival. It is important for weight-control after replacement.
