  • Clinical Analysis of Surgical Repair of Congenital Heart Disease for 787 Patients in Less Than 6 Months of Age

    Objective Summarize and review on surgical repair of congenital heart disease in infants. Methods Between January 1988 and June 2003, seven hundred and eighty seven less than 6 months of age patients were operated. There were 109 cases of complete transposition of the great arteries(D-TGA), 51 total abnormal pulmonary venous connection(TAPVC), 16 pulmonary atresia with ventricular septal defect(VSD), 33 coarctation of aorta, 299 VSD with pulmonary hypertention, 44 tetralogy of Fallot, 23 double outlet right ventricle, 9 pulmonary atresia with intact ventricle septum, et al. The operative procedure was dependent on different disease. Results There were 77 patients died, the total mortality was 9.78%(77/787). Following improvement of surgical procedure, the mortality was decreased from 25% in 1988-1995 to 4.11% in 2003. In the D-TGA patients, there was one residual VSD who was repaired 3 months late, and two had mild pulmonary and aortic supravalve obstruction. They were still be followed up. Two patients with intracardiac type of TAPVC had venous return obstruction, one was died and another was re-operated 4 days later. In the VSD patients, there were 5 patients with residural VSD, but all of them did not need to repair. Conclusion The time of surgical repair is very important, especially for complex congenital heart disease. The best operative procedure will be lost, if the infants is repaired too late, the postoperative events and mortality will be increased.

  • Clinical Analysis of Cardiac Surgery Concomitant with Bipolar Radiofrequency Ablation for Atrial Fibrillation

    ObjectiveTo evaluate the efficacy and safety of cardiac surgery concomitant with bipolar radiofrequency ablation(BRFA) for the patients with heart disease and atrial fibrillation(AF). MethodsFrom April 2008 to September 2014, clinical data of 167 patients(43 males, 124 females) of organic-heart-disease patients combined with atrial fibrillation were analyzed retrospectively in our hospital. Within 167 patients, 102 patients underwent bipolar radiofrequency ablation without aortic cross-clamping were as a trial group and the other 65 patients underwent cardiac surgery and bipolar radiofrequency ablation with aortic cross-clamping were as a control group. And there were no significant difference in the age and gender between the two groups. ResultsThe time of radiofrequency ablation was 23.1±5.0 minutes in all the patients and there was no significant difference between the two groups(P=0.279). The extracorporeal circulation time was 156.6±56.4 minutes and the aortic cross-clamping time was 82.1±42.6 minutes. There was a significant difference between two groups in extracorporeal circulation time and aortic cross-clamping time. One patient underwent bipolar radiofrequency ablation with aortic cross-clamping died of severe pulmonary infection and multiple organ dysfunction syndrome(MODS) in one month after the surgery. The duration of follow-up was 1-77(35.3±3.5) months. The sinus rhyme conversion rate was estimated by electrocardiogram(ECG) in 1 month, 3 months, 6 months, 12 months, 36 months, 60 months after operation. The sinus rhyme conversion rates were 85.3%(133/156), 83.4%(126/151), 82.7%(115/139), 77.0%(94/122), 75.9%(41/54), and 72.0%(18/25). There was no significant difference during the follow-up in all of the sinus rhyme conversion rate. During the fellow-up, 2 patients died. One died after 1 month and another died after 6 months after their hospital-discharges. ConclusionThe efficacy and safety of cardiac surgery concomitant with bipolar radiofrequency ablation is satisfied. It can reduce the time of myocardial ischemia in bipolar radiofrequency ablation without aortic cross-clamping. It is beneficial to critical patients.
