Pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals is a rare and complex lesion in which great morphologic variability exists regarding the sources of pulmonary blood flow. We report a case of this disease with no true central pulmonary arteries in a 9-month-old-boy successfully treated by one-stage complete unifocalization and repair from a midline stemotomy approach.

Ebsteins anomaly is a rare congenital cardiac malformation that is the downward displacement of the septal and posterior leaflets of the tricuspid valve into the ventricular apex, aresulting in the formation of an atrialized portion of the right ventricle. In most patients, symptoms such as cyanosis and progressive heart failure occur during the adolescence or young adulthood. The associated anomalies include ventricular septal defect, transposition of the great arteries, and malformation of the mitral valve. An 8-months-old male with Ebsteins anomaly, ventricular septal defect, and duplication of the mitral valve orifice successfully underwent operation with VSD patch closure. Postoperatively, cardiac size was significantly reduced and tricuspid regurgitation was trivial in echocardiography He has been doing well without any cardiac medication during the 18 months follow up after operation.

심장 탈장은 심낭을 열고 전폐절제술을 시행 후 드물게 발생되는 합병증으로 수술이 끝날때나 수술직후 발생된, 44세 남자환자에서 심낭을 열고 좌측 폐를 전절제술 후 심낭 결손부위를 인공조직으로 봉합하였다. 수술이 종료될 때 심장탈장이 발생되어 개흉에 의한 응급 복원을 시행하였으나 심한 저 산소성 뇌 손상이 발생되었다.

Background: Ventricular septal defect(VSD) that causes pulmonary hypertension increase right ventricular workload. Echocardiographic assessment of right ventricular systolic time interval (RVSTI) has been used to predict pulmonary artery pressure in various cardiopulmonary diseases. This study was undertaken in infants with simple VSD to observe the alteration of the right ventricular workload through the changes of RVSTI after repair of VSD. Material and Method: We evaluated heart rate, the ratio of the left atrium/aortic root diameter (LA/Ao), right ventricular pre-ejection period(RVPEP), right ventricular ejection time(RVET), and its ratio(RVPEP/RVET) as a predictor of right ventricular workload in 12 children with simple VSD. These were measured three times at the preoperative period, at the 3 month and between 6 month and 1 year(average 9.5${\pm}$1.8month) after repair of VSD by M-mode & Doppler echocardiograph from the pulmonic valve echogram. Result: Heart rate was decreased significantly after repair(137.1${\pm}$13.7 vs 114.4${\pm}$21.1 and 104.1${\pm}$10.2, p<0.01). LA/Ao ratio was decreased significantly after repair(1.71${\pm}$0.32 vs 1.47${\pm}$0.33 and 1.39${\pm}$0.23, p<0.05). RVPEP/RVET were decreased after repair (0.38${\pm}$0.09 vs 0.32${\pm}$0.08 and 0.29${\pm}$0.09, p<0.01). Heart rate corrected RVPEP/RVET were significantly decreased only after 6 months(0.32${\pm}$0.03 vs 0.30${\pm}$0.05 and 0.28${\pm}$0.06, p<0.05). Conclusion: We found elevated right ventricular workload was progressively decreased until more than 6 months after repair and the RVSTI may serve a useful guide in postoperative care for children with VSD.

Minimally invasive cardiac surgery using AESOP (Automated Endoscope System for Optimal Positioning) offers certain advantages such as better a cosmetic outcome, a shortened post operative recovery time and a shorten hospital stay, and these advantages are not achieved by conventional cardiac surgery. We report here on our first robot-assisted (AESOP) left minithoracotomy surgery in a 26 year-old female with a subarteral ventricular septal defect, and this might have been treated by median sternotomy before the development of AESOP.

Background: This study was undertaken in infant patients with isolated ventricular septal defect(VSD) to determine the effect of surgical closure on ventricular systolic time interval, as a parameter for ventricular performance, by echocardiography. Material and Method: Thirty patients were enrolled. Mean age of patients at operation was 6.5$\pm$3.2 months and all patients had non-restrictive VSD. We checked the left atrium/aorta(LA/Ao) ratio, left ventricle ejection fraction(EF), left ventricular systolic time interval(LVSTI), and right ventricular systolic time interval(RVSTI). Echocardiographic studies were done before surgical correction and postoperative periods(postopl: within 2 weeks, postop2: between 4 and 6 months, postop3: between 1 and 2 years). Result: LA/Ao ratio decreased significantly at immediate postoperative period compared to preoperative period and sustained during further follow-up period(from 1.74$\pm$0.37 to 1.36$\pm$0.24＊, 1.32$\pm$0.22＊, and 1.27$\pm$0.19＊, p<0.01). LV EF had not changed during follow-up periods(from 65.1$\pm$7.0 to 62.3$\pm$9.5, 62.8$\pm$5.7, and 64.1$\pm$6.9). LVSTI decreased significantly at postop2 and sustained during further follow-up period (from 0.46$\pm$0.13 to 0.46$\pm$0.11, 0.37$\pm$0.08＊, and 0.34$\pm$0.07＊, p<0.01). RVSTI decreased significantly at postop3(0.33$\pm$0.08 to 0.32$\pm$0.08, 0.31$\pm$0.07, and 0.27$\pm$0.05＊, p<0.01). Conclusion: We found that right and left ventricular systolic time intervals had decreased over the period of 1 year after surgical correction of VSD. Therefore, it is necessary to observe the change of ventricular function during that period.

The surgical management of patients with transposition of the great arteries, ventricular septal defect, and pulmonary stenosis remains a challenge. The Rastelli operation or Lecompte operation is the preferred surgical procedure, but its long-term results are not optimal because of a warped left ventricular outflow tract through a space-occupied intraventricular tunnel and a contrived right ventricular outflow tract. We performed a half-turned truncal switch operation as an alternative surgical procedure in a 3-year-old boy (weighing 9.6 kg) with this anomaly. Postoperative echocardiography showed laminar flow through straight and nonobstructive aortic and pulmonary ventricular outflow tracts.

Congenitally corrected transposition of the great arteries is a congenital cardiac anomaly with ventriculoarterial discordant connection and atrioventricular discordant connection. This report describes a 17 year old male patient who had congenitally corrected transposition of the great arteries associated with ventricular septal defect and patent ductus arteriosus, underwent patch closure of the ventricular septal defect and suture closure of patent ductus arteriosus, and was discharged on 9th day after surgery with good condition.
