Objective To compare surgical results between real-time three dimensional echocardiography（RT-3DE） guided closure of atrial septal defect （ASD） through a right minithoracotomy and traditional surgical repair under cardiopulmonary bypass （CPB）. Methods Sixty-four patients with secundum ASD received surgical repair in the First People’s Hospital of Honghe Autonomous Prefecture from April 2009 to April 2012. According to different surgical approach, all the patients were divided into group A and B. In group A, 35 patients underwent traditional ASD repair under CPB including 20males and 15 females with their age of 12-56 （16.4±4.0） years. In group B, 29 patients received real-time RT-3DE guidedASD closure through a right minithoracotomy without CPB, including 20 males and 15 females with their age of 15-50 （18.5±0.2） years. Operation time，postoperative mechanical ventilation time，hospital stay，chest drainage，mortality，morbidity and follow-up outcomes were compared between the 2 groups. Results Operation time （110.47±35.90 minutesvs. 159.32±20.60 minutes），postoperative mechanical ventilation time （10.40±22.30 hours vs. 16.40±12.20 hours），chestdrainage （106.71±85.20 ml vs. 146.70±75.63 ml）and postoperative hospital stay （4.0±1.0 days vs. 7.0±1.0 days）ofgroup B were significantly shorter or less than those of group A. In group A, 1 patient died postoperatively and 7 patientshad postoperative complications. In group B, there was no in-hospital mortality and 3 patients had postoperative complications.Postoperative morbidity of group A was significantly higher than that of group B （20.0% vs. 10.3%，P＜0.05） . ConclusionFor ASD patients with definite surgical indications，RT-3DE guided ASD closure through a right minithoracotomy has more advantages over traditional surgical repair under CBP.
Objective To therapy the atrial septal defect(ASD) much more better, comparative study of clinical outcomes in surgical treatment of ASD to other three minimally invasive procedures was performed. Methods From June 2007 to March2008, 652 ASD patients had undergone surgery（n=301）, transcatheter closure (n=274), openchest Hybrid closure(n=50) and without tracheal intubation Hybrid closure (n=27) of ASD. Patients were and divided into four groups according to the different procedures. Retrospectively we compared the data of patient’s age, hospital stay, trauma, cost of hospitalization, blood transfusion, anesthesia, tracheal intubation and postoperative fellowup. Results Median age and weight of openchest Hybrid and without tracheal intubation Hybrid groups were significantly less than those of the other two groups (Plt;0.01). The achievement ratio of four groups were 100.0％,97.2％,92.6％,100.0％. There was statistically difference in the achievement ratio of four groups (Plt;0.01). [CM(158.5mm]Median hospital stay and cost of blood transfusion of transcatheter closure and without tracheal intubation Hybrid groups were significantly less than other two groups (Plt;0.01). The mean cost of hospitalization in four groups were 24 802.90±360.96￥，25 095.07±437.13￥，24 856.77±445.87￥，24 853.56±673.99￥ respectively. There was no statistically difference in the cost of hospitalization(Pgt;0.05). All patients were recovered and discharged without eventuality. The mean followup time were 4.64±0.32 month，4.57±0.31 month，4.49±0.28 month，4.62±0.31 month. There was no statistically difference in the followup time (Pgt;0.05). The complication rate of postoperative incision were 3.32％，0.47％，6.00％，0.00％. The transcatheter closure and without tracheal intubation Hybrid groups were significantly less than other two groups (Plt;0.01). Conclusions The mean cost of hospitalization in four procedure were almost the same. The ability to close any ASD regardless of its size, location or patient’s age remains an important advantage of surgery. Transcatheter closure of ASD has the advantage of less complications. But there are limitationsto lowerweight and infant patients. OpenChest Hybrid closure offers a valuable and complementary operative approach for any age patients. Without extracorporeal circulation, it reduces trauma significantly but it always has few surgery injury. Without tracheal intubation Hybrid closure without tracheal intubation can be used for patients of any age. The cost of hospitalization is not higher than surgical treatment and transcatheter closure. The success of procedure is high and the incidence of postoperative complications is lower. It is an ideal treatment to infant ASD patients especially to lowerweight and younger infant patients.
Objective To summarize the experiences of surgical treatment for partial atrioventricular canal defect. Methods The data of 66 patients of surgical treatment for partial atrioventricular canal defect from January 1984 to December 2007 were analyzed retrospectively. The cleft of mitral valve presented in all of those patients. There were 52 cases with direct suture on cleft, 8 cases with direct suture with commissurroplasty, 1 case with posterior leaflet plasty, 3 cases with direct suture St.Jude ring and 2 cases mitral valve replacement. The ostium primum atrial septal defects were repaired with patches of Dacron in 12 cases and autologous pericardium in 54 cases. Coronary sinus was situated on the left atrium in 5 and ostium primum atrial septal defects were repaired in Kirklin’s way; the others in MeGoon’way. Meanwhile other heart abnormalities were done. Results There were two early deaths (3.03%), one patient died of heart arrhythmia and one patient died of respiratory failure. Complications of total A-V block was in 2 cases. Both of them were replanted with pace makers.52 cases were followed up, followup time was 5 months to 22 years(mean follow-up 15 years). All patients had better life. Four patients have been re -operated for different reasons post primary operation. One had good result after re-mitral valve replacement. One case died of acute renal failure and the other two died of low cardiac output syndrome. Conclusions Early operation is definitely recommended when the diagnosis is confirmed. Because the structure or function of mitral valve is saved, pulmonary hypertension is avoided and the mortality is lower in the future. The key points of operation are to rectify the mitral insufficiency, repair ostium primum atrial septal defects and avoid atrioventricular block. The patients of mild regurgitation of mitral valve have good results. Provided in those have more than middle regurgitation of mitral valve then their longterm results are poor.
Objective To summarize the experience of surgical treatment of complete atrioventricular canal defect （CAVCD） in 94 patients. Methods Ninety-four patients with CAVCD underwent surgical therapy. CAVCD were repaired by using two-patch technique in 65 patients and using single-patch technique in 29 patients. Additional cardiovascular anomalies were corrected simultaneously. Results There were 10 hospital deaths （10.6%）, 4 patients were less than 6 month old. Four patients died of severe mitral valve regurgitation, 3 died of pulmonary hypertensive crises and 3 died of low cardiac output syndrome, cerebral complications and aerothorax separately. Follow-up was completed in 84 patients, with a duration of 3-6 months. Mild degree mitral valve regurgitation was observed in 18 patients by echocardiography, mild to middle degree mitral valve regurgitation was observed in 12 patients. Conclusions Postoperative severe mitral regurgitation and pulmonary hypertensive crises were the main cause of deaths for correction of CAVCD. Early correction of CAVCD and satisfactory reconstruction of atrioventricular valve could obtain a satisfactory result, routine evaluation with intraoperative transesophageal echocardiography could result in a low operative mortality.

Method The 100 patients with ASD were selected on transthoracic echocardiography (TTE) and TEE. During operation, TEE was applied to monitor the procedure of occlusion, to guide the occluder cites, to evaluate the effects and to make sure if there were peripheral residual shunts around the occlusion and other complications. Results All of the patients were exactly diagnosed by TTE and TEE，guiding and evaluating the successful closed ASD. The successful rate of occlusion was 96%，the failure rate was 4%. The review after surgery showed that, there were no residual review, pleural effusion in three patients. The concordance rate of TTE and TEE diagnosis result is 40%. TEE diagnosis amend the preoperative TTE diagnosis in 60 patients (60%). Conclusions TEE plays an important role in select inpatients，determining the size of the occluder，correctly before occlusion operation, guiding the placement of the occluder in operation and evaluating the effect after operation.
ObjectiveTo compare clinical outcomes between biatrial ablation and right atrial ablation in the surgical treatment of atrial fibrillation (AF)for adult patients with atrial septal defect (ASD). MethodsClinical data of 47 patients with ASD and AF who underwent surgical ASD repair and radiofrequency ablation from January 2007 to December 2012 were retrospectively analyzed. There were 20 male and 27 female patients with their age of 35-76 years. AF duration ranged from 3 months to 15 years. There were 18 patients with persistent AF and 29 patients with long-standing persistent AF. There were 10 patients with mild-to-moderate or more severe mitral regurgitation (MR), and 28 patients with mild-to-moderate or more severe tricuspid regurgitation (TR). According to different surgical strategies, all the 47 patients were divided into 2 groups. In right atrial ablation group, there were 19 patients who received ASD repair and right atrial ablation. In biatrial ablation group, there were 28 patients who received ASD repair and biatrial ablation. For patients with mild-to-moderate or more severe MR or TR, concomitant mitral or tricuspid valvuloplasty was performed. All the patients received 24-hour Holter monitoring at 3, 6 and 12 months after discharge, and were intermittently followed up thereafter. ResultsCardio-pulmonary bypass time, aortic cross-clamping time and postoperative hospital stay of biatrial ablation group were significantly longer than those of right atrial ablation group. But there was no statistical difference in postoperative morbidity or recovery between the 2 groups. After heart rebeating, there were 25 patients (89.3%)with sinus rhythm (SR)and 3 patients with junc-tional rhythm (JR), and none of the patients had AF in biatrial ablation group. There were 14 patients (73.7%)with SR, 2 patients with JR and 3 patients with AF in right atrial ablation group. At discharge, 28 patients (100%)in biatrial ablation group had SR, and in right atrial ablation group there were 15 patients (78.9%)with SR and 4 patients with AF relapse (P=0.045). All the patients were followed up for 3-75 months, and there was no death or residual ASD shunt during follow-up. Two patients had mild-to-moderate or more severe MR, and 4 patients had mild-to-moderate or more severe TR. Cumulative SR maintenance rate of biatrial ablation group (87.7%±6.7%)was significantly higher than that of right atrial ablation group (47.4%±11.5%, P=0.003)at 2 years after discharge. ConclusionFor adult patients with ASD and AF, biatrial ablation can produce better clinical outcomes than right atrial ablation without increasing surgical risks.
ObjectiveTo summarize clinical outcomes of atrial septal defect (ASD)occlusion for patients with ASD and tricuspid regurgitation (TR). MethodsBetween July 2006 and January 2012, 98 patients with ASD and TR under-went ASD occlusion in Xinhua Hospital, Shanghai Jiaotong University School of Medicine. There were 36 male and 62 female patients with their age aging from 2 months to 80 years. All ASD were secundum ASD with their diameter of 3-23 mm. There were 60 patients with mild TR, 28 patients with moderate TR, and 10 patients with severe TR. All the patients received ASD closure without specific management for TR, including 51 patients under digital subtraction angiography (DSA), 46 patients via a minithoracotomy approach, and 1 patient guided by transthoracic echocardiography. All the patients were followed up with echocardiography to evaluate changes of TR after ASD closure. ResultsThere was no in-hospital death. ASD occlusion was not successful in 1 patient who was found to have residual ASD shunt on the third postoperative day. Another patient underwent reexploration for abnormal bleeding on the third postoperative day. All the other patients had uneventful postoperative recovery. Eighty-four patients were followed up for 1-64 (26.56±21.35)months. During follow-up, the patient who have residual ASD shunt on the third postoperative day received open chest repair 6 months after discharge. TR of 73 patients (86.90%)improved in different degrees. Preoperative severe TR in 10 patients changed into mild TR in 8 patients, moderate TR in 1 patients and still severe TR in 1 patient. Preoperative moderate TR in 26 patients changed into none TR in 6 patients, mild TR in 18 patients and still moderate TR in 2 patients. Preoperative mild TR in 48 patients changed into none TR in 40 patients and still mild TR in 8 patients. ConclusionFor patients with ASD and TR, conservative treatment strategy is recommended. Simple ASD closure can provide satisfactory clinical outcomes, and also avoid adverse complications of cardiopulmonary bypass including myocardial injury and lung injury.
ObjectiveTo investigate clinical outcomes of isolated atrial septal defect (ASD)repair on the beating or non-beating heart through minimally invasive right axillary approach. MethodsForty-five patients underwent isolated ASD repair through minimally invasive right axillary approach in Research Institute of Surgery, Daping Hospital of the Third Military Medical University from September 2009 to August 2011. According to different surgical techniques, all the patients were divided into a beating-heart group and a non-beating heart group. In the beating-heart group, there were 22 patients including 13 males and 9 females with their mean age of 3.2±2.1 years and body weight of 13.1±4.0 kg. There were 20 patients with ostium secundum ASD and 2 patients with ostium primum ASD. Mean ASD diameter in the beating-heart group was 12.2±5.1 mm. In the non-beating heart group, there were 23 patients including 14 males and 9 females with their mean age of 3.5±2.5 years and body weight of 12.9±3.3 kg. There were 18 patients with ostium secundum ASD, 3 patients with sinus venosus ASD, and 2 patients with ostium primum ASD. Mean ASD diameter in the non-beating heart group was 11.6±4.7 mm. Serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST)and highly sensitive cardiac troponin I (cTnI)were examined preoperatively, after weaning from cardiopulmonary bypass (CPB), 6 hours and 24 hours postoperatively. ResultsThere was no in-hospital death. Postoperatively, 1 patient had right atelectasis and another patient had right pneumothorax. CPB time and operation time of the beating-heart group were significantly shorter than those of the non-beating heart group (P < 0.05). There was no statistical difference in intraoperative blood transfusion, mechanical ventilation time, length of postoperative ICU stay or hospital stay, chest drainage within 24 hours postoperatively, or postoperative cardiac function between the 2 groups (P > 0.05). Preoperative levels of CK, CK-MB, AST and cTnI were all within the normal limit, and there was no statistical difference between the 2 groups (P > 0.05). After CPB, CK, CK-MB, AST and cTnI levels increased in both groups, but increased significantly greater in the non-beating heart group (P < 0.05). Postoperative levels of CK, CK-MB, AST and cTnI of the beating-heart group were significantly lower than those of the non-beating heart group (P < 0.05). ConclusionIsolated ASD repair on the beating heart via minimally invasive right axillary approach is a safe and cosmetic procedure with shorter operation time and less myocardial injury.
ObjectiveTo evaluate the advantages and disadvantages of parasternal minimally incision surgery over median sternotomy to treat atrial septal defect (ASD) patients. MethodsWe retrospectively analyzed the clinical data of 55 ASD patients received ASD closure under cardiopulmonary bypass (CPB) in Department of Cardiovascular Surgery, West China Hospital from November 2010 through March 2014. There were 16 males and 39 females with an average age of 25.8 (range, 9-56 years). All the patients were divided into two groups depending on different surgical approach:a median sternotomy group (a MS group, 15 patients)and a parasternal minimally incision group (a PMI group, 40 patients). There was no statistical difference in age, gender, weight, cardiac function classification (NYHA), and atrial septal defect diameter between the two groups (P>0.05). We analyzed the clinical data of the patients and followed up for 6 months. ResultsAfter operation, no death occurred in the two groups. One patient in the MS group prolonged hospitalization due to poor postoperative heart function. One patient in the PMI group prolonged hospitalization because of pulmonary infection. Patients in the PMI group had longer operation time (P=0.007) and cardiopulmonary bypass (CPB) time (P < 0.001), higher cost in hospital (P=0.040), less intraoperative blood loss, less postoperative drainage volume on the first day (both P < 0.001). There was no statistical difference in aortic clamp time (P=0.500) mean hospital stay (P=0.290) after operation between the two groups. To eliminate the interference of the learning curve, there was no statistical difference in operation time (P=0.275) and hospitalization cost (P=0.188) between the two groups. While there was a statistical difference in CPB time between the two groups (P=0.007). There was no remnant shunts or wound complications in the two groups at the end of following up for 6 months. More patients in the PMI group could engage in non-strenuous activities with a statistical difference (P < 0.001). ConclusionParasternal minimally incision in the treatment of atrial septal defect is safe, effective, minimally invasive, with easy operation and shorter learning curve. It can be used as an important part of minimally invasive treatment procedure of congenital heart disease.
Objective To investigate the surgical treatment of adult secondary atrial septal defect with paroxysmal atrial fibrillation. Methods We retrospectively analyzed the clinical data of 84 patients with adult secondary atrial septal underwent surgical treatment in Beijing Anzhen Hospital from January 2002 through May 2013. There were 31 males and 53 females at mean age of 56.3 (24-72) years. Eleven patients were treated by cardiopulmonary bypass operation with 6 patients by radiofrequency catheter ablation simultaneously. Seventy three patients were implanted with septal defect closure with 52 patients by radiofrequency ablation simultaneously. Rhythm of the heart was detected at the immediate postoperative period, 7 days, 3 months and 6 months after the operation. Results No preoperative death, thoraecotomy and no arrhythmic complications in all the patients no matter with or without RF occurred. In the patients with cardiopulmonary bypass operation, the time of aortic occlusion was 35.21±12.32 min, the cardiopulmonary bypass time was 45.67±16.93 min, and the ICU observation time was 11.87±12.36 hours. In the patients with septal defect closure implanted, ICU observation time was 10.93+13.67 hours. The incidences of atrial fibrillation in the patients with radiofrequency ablation on postoperative 7 days，3 months and 6 months were lower than those in the patients without radiofrequency ablation (P<0.05). Conclusion For adult secondary atrial septal defect patients with paroxysmal atrial fibrillation, no matter cardiopulmonary bypass operation or septal defect closure implanted, radiofrequency ablation at the same time is safety and can reduce incidence of recurrence of atrial fibrillation.
