摘要: Abstract Background . Aortic valve replacement is a common procedure in elderly patients. There has been great deal of controversy about the risks associated with early mortality. Uncertainty risk small continues to remain controversial. This study was designed identify factors influencing mortality and establish an accurate model for prediction in-hospital Methods One hundred eighty septuagenarians octogenarians (58% women; mean age, 76 ± 4.7 years) underwent primary isolated aortic between 1986 1997. overall 16.7% (n = 180). Patients body surface area less than 1.8 m 2 had 23.2% 95) compared 8.1% 74; p 0.009) patients or more. cardiopulmonary bypass time 100 minutes experienced 8.9% 56) 10.2% 59) on 124 29.6% 64) pump longer ( 0.040). Results Multivariate logistic regression analysis identified long as independent factors. A higher seen female receiving smaller valves. However, there strong correlation area, size, gender. Conclusions Small are two undergoing replacement. The use valves does not influence
