We reviewed our experience with 19mm size aortic valve prostheses for cases with small aortic annulus. Forty-six patients operated on between 1990 and Septembr 2002 were enrolled in this study. Clinical late assessment was performed to evaluate the incidence of valverelated complications, residual transprosthetic gradient, left ventricular mass index (LVMI), and NYHA functional class. Postoperative echocardiography was performed to evaluate hemodynamic performance of the prostheses. Follow up was 1 to 12.7 years (mean 5.3±3.6). There was no hospital mortality (0%). Actuarial survival rates at 10 years were 81.4±1.5%. The late postoperative peak gradient was 25±11mmHg. LVMI was significantly reduced in late phase. NYHA functional class significantly improved in the late period. Although 19mm size aortic valve prosthesis remains small transprosthetic pressure gradient, LVMI significantly reduced and patient activity was satisfactory maintained in the late period.
