To define the determinants of perioperative death and complications after cardiac valve replacement in 702 patients.
Clinical data of the patients after cardiac valve replacement were analyzed retrospectively.
Perioperative mortality and morbidity correlated significantly with some of the perioperative variables, such as higher NYHA functional class (III or IV), large left ventricular end-diastolic diameter (>/= 70 mm), C/T >/= 0.70, prolonged aortic cross-clamping time and cardiopulmonary bypass time, unsatisfactory myocardial protection.
Perioperative mortality and morbidity correlate significantly with some of perioperative variables, such as higher NYHA functional class, unsatisfactory myocardial protection, inappropriate surgical procedure, improper therapy of some complications after cardiac valve replacement. To avoid the occurrence of these independent predictors or to correct them timely might effectively decrease the perioperative mortality and morbidity after cardiac valve replacement.
确定702例心脏瓣膜置换术后围手术期死亡及并发症的决定因素。
回顾性分析心脏瓣膜置换术后患者的临床资料。
围手术期死亡率和发病率与一些围手术期变量显著相关，如纽约心脏协会（NYHA）心功能分级较高（III或IV级）、左心室舒张末期内径较大（≥70mm）、心胸比率≥0.70、主动脉阻断时间和体外循环时间延长、心肌保护不佳。
围手术期死亡率和发病率与一些围手术期变量显著相关，如NYHA心功能分级较高、心肌保护不佳、手术操作不当、心脏瓣膜置换术后某些并发症治疗不当。避免这些独立预测因素的出现或及时纠正它们可能有效降低心脏瓣膜置换术后的围手术期死亡率和发病率。
