Objective To review the experience of surgical repair of aortic origin of pulmonary artery.Methods Fifteen patients underwent surgical correction for aortic origin of pulmonary artery.All of the patients had anomalous origin of right pulmonary artery,and 11 were associated with patent ductus arteriosus,6 with patent foramen ovale,3 with atrial septal defect,2with aortic pulmonic window,1 with ventricular septal defect,1 with interruption of aortic arch,1 with coarctation of aorta and 1 with pulmonary vein stenosis.All patients were associated with severe pulmonary hypertension.All patients were operated on with the implantation of the AORPA to the main pulmonary artery derectly.Results All 15 patients were cured and no died.1 lost follow-up and the other 14 were survivable during a follow-up 3 months to 81 months.one patient recepted pacemaker implantation 2 years after operation because of sinus arrest,no other patients required reoperation.Conclusion Echocardiography combined with spiral ct angiography is a good method for AOPA diagnosis.Good surgical outcome and low reoperation rate of aortic origin of pulmonary artery can be achieved by direct anastomosis.

Objective To review the experience of anomalous origin of the left coronary artery from the pulmonary artery.Methods 36 patients were admitted,17 males and 19 females,the median age was 9.5 months.12 were associated with severe mitral regurgitation,10 with left ventricular aneurysm,1 with patent ductus arteriosus,2 with patent foramen ovale.33 pa tients underwent surgical repair,of which 3 underwent left coronary artery (LCA) ligation,1 underwent mitral valve replacement,29 underwent reestablishment of a dual coronary system with direct aortic reimplantation of the left coronary artery into the aorta,incidental mitral valvoplasty in 7 patients,mitral valve replacement in 1,patent ductus arteriosus ligation in 1 and patent foramen ovale closure in 2.Results Two patients died in the hospital,one postoperative patient lost follow-up,one underwent LCA reimplantation suddenly died 3 days after discharged,one received coronary artery bypass graft 2 years after LCA ligation,the remainder were asymptomatic during a follow-up of 1 to 73 months.one of the patients who did not underwent surgical repair lost follow-up,when one suddenly died 2 months after discharged,the remained one was asymptomatic during a follow-up of 5 months.Conclusion Echocardiography combined with spiral CT angiography is a good method for ALCAPA diagnosis.Good surgical outcome of ALCAPA can be achieved by reestablishing a dual coronary system with direct aortic reimplantation of the left coronary artery into the aorta,and left ventricular dysfunction could be significantly improved.Incidental mitral valvoplasty may be helpful in early rehabilitation but poor in long-term prognosis.Left ventricular aneurysm could be improved so a incidental resection of left ventricular aneurysm was not suggested.

Objective To evaluate the right heart function with echocardiography after right ventricle-pulmonary artery (RV-PA) anastomasis for right ventricle outflow (RVOT) reconstruction in patients with different types of pulmonary atresia and ventricle septal defect(PA/VSD).Methods From Nov 2002 to Aug 2013,31 patients with PA/VSD had undergone right ventricle-pulmonary anastomasis to reconstruct RVOT for radical or palliative repair.Related echocardiography indexs including strain/rate etc.were used to evaluate the right heart function and the progress of the right heart valves regurgitation.Results There were 3 early hospital deaths.No later death during follow-up.The echocardiography suggested the pulmonary artery and tricuspid regurgitation were more serious,however,the right heart function was relatively fine.The regurgitation of tricuspid valve was positive correlation with duration of follow-up (P =0.016).Conclusion The right heart function in follow-up keeps relatively well,and tricuspid valve regurgitation needs a long-term follow-up.

Objective To evaluate the outcomes of surgical repair of typeⅢ pulmonary atresia with ventricular septal de-fect( PA/VSD) .Methods Retrospectively analyzed the clinical data of 98 patients with type Ⅲ PA/VSD who underwent sur-gical repair in the Department of Cardiovascular Surgery , Guangdong Cardiovascular Institute from September 2005 to December 2014.There were 54 males and 44 females at the mean age of(4.2 ±4.8) years and the mean weight of(13.2 ±10.0) kg. There were 67 patients in palliative repair group and 31 patients in radical repair group .There were 85 patients underwent on-pump operation including 9 beating heart cases.Results The mean bypass time was(121.2 ±49.4)min, the mean aorta cross-clamping time was(75.4 ±31.8) min.The overall postoperative mortality was 6.1%(6/98).For the survival patients, the mean ventilation time was(106.7 ±184.3) h, the mean ICU stay was(8.9 ±10.9) days and the mean hospital stay was (33.4 ±17.0)days.During follow-up period, 28 patients were underwent re-operation, the postoperative mortality was 7.1%(2/28).There were no differences in postoperative status between two groups.Conclusion The outcomes of surgical repair for type Ⅲ PA/VSD was good.Preoperative evaluation of the pulmonary development and MAPCAs were helpful for choosing surgical options.Re-operation was recommended to those appropriate patients.

Objective To summarize the experience and early outcomes of surgical treatment of adult tetralogy of Fallot (ATOF).Methods We retrospectively analyzed the clinical data of 227 patients with ATOF who underwent surgical repair in the Department of Cadiovascular Surgery,Guangdong Cardivascular Institute from January 2004 to December 2014.There were 112 males and 115 females at a median age of 34 years(range,18 to 58 years) and a mean weight of(49.00 ± 8.27) kg.All patients were underwent one stage repair,including 129 cases with transannular patch and 61 cases with MAPCAs in which 4 cases were underwent hybrid occlusion.Results There were 12 cases died in hospital(5.3％),24 cases with Re-thoratomy for hemaostsis,5 cases with poor wound healing,10 cases with postoperative pneumonia.There were 25 cases with residual VSD including 8 cases caused by surgeon in congenital heart disease department and 17 cases caused by surgeon in adult heart disease department(P ＜ 0.05).The repair with transannular patch required significantly longer bypass time [(87.83 ± 26.02) min vs.(78.47 ± 26.00) min,P =0.009].The cases with MAPCAs had higher cost than that with no MAPCAs [(83 137.01 ±69363.05) RMB vs.(66 184.29 ±44219.38) RMB,P=0.03].Conclusion The early outcomes of ATOF is good.The cases with MAPCAs had higher cost than that with no MAPCAs.The CHD surgeon had lower probability of residual VSD.Preoperative evaluation of MAPCAs by CHD surgeon and perioperative maintain of the right ventricular function were helpful.

Objective The results of repair for TOF with anomalous coronary artery(ACA) were studied to determine the incidence of coronary anomalies and evaluate surgical strategy choicesas well as postoperative outcomes.Methods From January 2008 to August 2014,1142 consecutive patients underwent repair of TOF including 44 patients with TOF and ACA:single coronary artery in 15,dual anterior descending coronary in 15,single left anterior descending coronary arising from the rightcoronary artery in 3 and the other ACA in 5.The median age was 5.7 years (range,1 month-27 years),and the median weight was 16.0 kg(range,4.5-51.0 kg).Surgical procedure was selected according to the extent of right ventricular outflow tract (RVOT) obstruction and distribution of the ACA.Results There was one operative death.No deaths during the follow-up period in the other 37 patients.Single patch techniquewasperformed in 15.RVOT residual obstruction detected in 7 who without transannular patch,and one need reoperation;Two patch technique was performed in 6,and 3 of them required an additional RV-PA(pulmonary artery) tube because of RVOT residual obstruction during the operation;Double oullet technique was in 6.No tube stenosis occurred in follow-up period time;PA translocation technique was in 11.The right PA stenosis was detected in 4;ACA was ligated and divided in 3,then RVOT reconstruction was performed.Conclusion The combination of ACA is not a contraindication to primary repair of TOF.But there are many anatomiacal variations of ACA,and the accuracy of preoperative diagnosis is low.So proper selection of surgical approach should be individualized based on the careful intraoperative identification of the distribution of the ACA as well as the location and degree of the RVOT obstruction.

Objective To compare the two different ways of right ventricular outflow tract(RVOT) reconstruction at repair of pulmonary atresia with ventricular septal defect,the direct RV-PA anastomosis and pericardial conduit to find the better way.Methods From Jun.2002 to Oct.2012,66 patients underwent pulmonary atresia with ventricular septal defect repair in our hospital,age at operation from 14 days to 272 months.Patients were divided into 2 groups according to the way of RVOT reconstruction.Group 1:31 of them,using direct RV-PA anastomasis,Group 2:35 of them,using pericardial conduit.Paired t test was used to evaluate the growth of pulmonary arteries.Chi-square test and Kaplan-Meier were used to calculate the postoperative mortality,reopemtion situation and survival time.Results There are 3 early hospital death in group 1 (9.7 ％),and 5 in group 2(14.3％),P =0.71.There is a significant difference between the two groups in restenosis rate of the RV-PA anastomasis and autologous pericardial conduit with pulmonary branch artery(Group 1:22.2％,Group 2:55.6％,P =0.01).The diameters of RV-PA anastomasis and the pulmonary artery branches in follow-up were significantly lager than the earlier diameters(P ＜ 0.05) in group 1.There is no growth on diameters of the pericardial conduit and pulmonary branches except the right pulmonary artery in follow-up in group 2.There is no significant difference between the two groups in later survival(P =0.30).Conclusion Both the direct anastomasis of RV-PA and pericardial conduit are available for RVOT reconstruction in pulmonary atresia with ventricular setal defect repair.There is lower incidence of RVOT and pulmonary stenosis and anastomosis absolutely has the ability for later growth in the former.

Objective Retrospectively analyze surgical correction supracardiac total anomalous pulmonary venous con-nection (TAPVC) using sutureless technique to prevent post-repair pulmonary vein stenosis. Methods Between December 2007 and December 2008, 25 children cases of total anomalous pulmonary venous connection underwent primary surgical cor-rection. The anatomic types of TAPVC were supra cardiac in nine patients, inha cardiac in one, mixed in 3 and intra cardiac in 12. Five of nine supra cardiac TAPVC underwent correction using sutureless technique. There were 2 male and 3 female. Their age at surgeries ranged from 2 months to 13 years, and the body weight were from 4.5 kg to 2.1 kg with an average of (7.9±6.4) kg. After median sternotomy and opening the pericardium, the heart was arrested by delivering cold crystal ear-dioplegia. The heart was then positioned toward the patient' s right and under the right henri sternum. A generous incision across the posterior wall of the left atrium and one on the common pulmonary vein was made. The latter was extended upwards to the midpoint of the vertical vein. The left atrium was subsequently connected to the pulmonary venous confluence by suturing the edge of the atrium to the posterior mediastinal pericardium that surrounding the common pulmonary vein and the vertical vein with 7-0 PDS. The vertical vein was partially ligated after conclusion of CPB, leaving a diameter of 5mm shunt. Routine follow-up with echocardiogram were at diacharging, 3 months, 6 months and 1 year after surgery. Results All 5 cases survived uneventfully excopt 1 baby on ventilation over 7 days after surgery, who had bilateral lung consolidation before the operation. Echocardiogram showed satisfactory results with maxium velocity acrossing the anastomosis of 0.65 -0.85 m/s. Conclusion Sutureleas technique can avoid trauma to the pulmonary venous endothelium and minimize the tension of anastomasis. It may play an important role to prevent post-repair pulmonary vein stenosis. More patients with long-term follow-up are necessary to draw a definite conclusion of this technique.

Objective The aim of this study is to retrospectively analyze surgical management of absent pulmonary valve syndrome(APVS).Methods Between January 2005 and January 2012,totally 11 children with APVS underwent primary surgical correction.There were 7 boys and 4 girls.Age at surgeries range from 1 to 5 years,and wcight from 10.2-17.5 kg,with average (12.3 ± 3.4) kg.Surgical procedures include VSD repair,pulmonary arteries reconstruction and RVOT reconstruction with monocusp valve.5 cases chose Lecompte maneuver as an option to release compression to bronchus,5 cases underwent fibroscopy inspection and airway secretion suction,and 4 cases adapted deep hypothermic circulatory arrest (DHCA)during correction procedures.All survivors are routinely followed-up with echocardiogram.Results All 11 cases survived,2 of them suffered from frequent lungs infections during the first year post surgery.No case exists bronchus or pulmonary arteries compression.Conclusion APVS is a rare congenital heart defect,which may challenge perioperative managements and operations.Ideal surgical correctiou includes RVOT reconstruction,decompression of bilateral bronchus,and airway inspection with fibroscopy.However,compression of intrapulmonary bronchi by abnormally branching pulmonary arteries may expose patients to a relative long time of medication therapy after surgical correction.A large number of patients with long-term follow-up are needed to draw definitive conclusions on this strategy' s effectiveness.
