摘要: Abstract Background . Mortality, morbidity, complication rates, and echo hemodynamic results using the Cryolife O'Brien stentless aortic bioprosthesis over a 5-year period are reported. Methods The valve was implanted in 97 conscecutive patients, 54 male 43 female, mean age 70.9 ± 6.5 years. All patients underwent preoperative, discharge (early study), 6-month (intermediate late (18.3 10.4 months) echocardiography. Results actuarial survival rate 93.9% 3%. Aortic regurgitation absent 95.5%, mild 3.4%, moderate 1.1%. Peak systolic gradients were significantly lower at ( p = NS). effective orifice area index Left ventricular mass decreased early postoperatively 0.04). Conclusions of this showed low valve-related complications with excellent performance all sizes.
