Objective To analyze the diagnosis and treatment of patients with ventricular septal defect complicated with infective endocarditis.Methods We retrospectively analyzed the clinical data of 40 patients with ventricular septal defect complicated with infective endocarditis in our hospital from 2001 to 2016. There were 25 males and 15 females, aged 20-62 (39.92±11.16) years. They were divided into two groups according to the duration from admission to surgery: a group A (an early operation group whose surgery was performed within 7 days after admission) and a group B (a conventional treatment group with the duration from admission to surgery>7 days). Among them, there were 27 patients in the group A including 15 males and 12 females with an average age of 39.56±11.80 years, and 13 patients in the group B including 10 males and 3 females with an average age of 40.69±10.13 years. All patients were examined by echocardiogram and blood bacterial culture to investigate their etiology, echocardiogram results and treatment status. And the clinical data of the two groups were compared.Results Two patients died before operation in the group B, one died of heart failure, and one cerebral infarction. No reoperation during hospitalization, cerebral infarction, thromboembolism or other complications occurred. The ventilation time in the group A was significantly shorter than that in the group B (18.00±14.85 h vs. 31.00±29.57 h, P=0.015). There was no statistical difference in the extracorporeal circulation time, myocardial block time, or postoperative hospital stay between the two groups (P>0.05). After discharge, the patients continued antibiotic therapy for 3-6 weeks. Patients were followed up for 12-127 (75.74±6.01) months, 1 died of malignant tumors in the group A, 1 developed atrial fibrillation and 1 developed cardiac insufficiency in the group B, and the rest of patients did not complain of obvious discomfort. There was no residual shunt, recurrence of infective endocarditis, reoperation, postoperative stroke or thromboembolism.Conclusion Preoperative echocardiography and blood bacteriological culture are helpful for the diagnosis and treatment of patients with ventricular septal defect complicated with infective endocarditis. Early surgery is safe and effective for these patients, and can improve the long-term survival rate.
