目的探讨中、老年先天性Ⅱ孔房间隔缺损患者的临床特点以及继发肺动脉高压的相关因素。方法对45例40岁以上的先天性Ⅱ孔房间隔缺损患者的临床资料进行回顾性分析。结果老年组左心室舒张功能显著下降,肺动脉高压发病率显著高于中年组。肺动脉压力与房间隔缺损直径大小显著相关。老年组或肺动脉压力增高患者,手术治疗受到限制。结论老年先天性Ⅱ孔房间隔缺损患者容易合并肺动脉高压、心力衰竭、心律失常等并发症;老年患者手术治疗的适应证有待改进。
Objective To investigate the clinical features of secondary congenital heart failure in elderly patients with atrial septal defects and related factors of secondary pulmonary hypertension. Methods The clinical data of 45 patients with congenital Ⅱ atrial septal defect older than 40 years were analyzed retrospectively. Results The left ventricular diastolic function was significantly decreased in the elderly group, the incidence of pulmonary hypertension was significantly higher than the middle-aged group. Pulmonary artery pressure and atrial septal defect size was significantly correlated. Elderly patients or patients with pulmonary hypertension, surgical treatment is limited. Conclusions Elderly patients with congenital â ... ¢ atrial septal defect easily complicate pulmonary hypertension, heart failure, arrhythmia and other complications; indications for surgical treatment of elderly patients need to be improved.
