Clinical analysis for 241 cases of subpulmonic ventricular septal defect / 中国医师进修杂志

ABSTRACT

Objective To summarize the clinical features and treatment experience of subpulmonic ventricular septal defect (SPVSD). Method The clinical data of 241 cases of SPVSD were analyzed retrospectively. Results Two hundred and fifteen cases were confirmed by echocardiography before operation, while other 26 cases were misdiagnosed (10.79%, 26/241), 42 cases with aortic valve prolapsed,ECG showed left ventricular hypertrophy. All patients underwent surgical repair of VSD. Other procedures had been done in the same stage including aortic valve replacement (AVR) in 8 cases, aortic valvuloplasty (AVP) in 6 cases and other operations. The size of VSD was larger than the value echocardiography measured before operation. There were no perioperative death and no complete atrioventricular block. Two hundred and thirty cases (95.44%, 230/241) were followed up for 3 months to 5 years. The cardiac function (NYHA) in 189 cases were grade Ⅰ and 41 cases were grade Ⅱ. There was no residual shunt of VSD. Among patients who underwent AVP or AVR, 1 case developed mild insufficiency, others developed well. Others underwent another operations all developed well. Conclusion To achieve satisfactory results, it should enhance the overall understanding of SPVSD, improve the diagnostic accuracy of SPVSD, take positive surgical repair of VSD and reasonable treatment with aortic valve disease, and other malformation or disease.
