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 experiences of surgical treatment of sinus venosus atrial septal defect （SVASD）. Methods There were 32 patients of SVASD, all of them were associated with totally or partially right anomalous pulmonary venous connection. There were 25 cases of superior SVASD, 22 cases underwent double-patch procedure, 3 cases underwent Warden procedure. In 7 cases of inferier SVASD, 3 cases of Scimitar syndrome underwent ASD repair by pericardial patch and at the same time the anomalous pulmonary vein was divided and reimplanted to the posterior wall of left atrium, 4 cases of them underwent single-patch ASD repair. Results The surgical results were satisfying and no patient died, 28 patients were in sinus rhythm and echocardiography showed neither obstruction of caval vein and right pulmonary vein nor residual interatrial shunt. Conclusion SVASD mostly associated with right anomalous pulmonary venous connection according to its special anatomic structure. Preserving the function of sinus node and avoiding of obstruction of caval vein should be routinely considered when superior SVASD was repaired. The heart function of Scimitar syndrome should be followed-up for a long time for it usually associated with right lung hypoplasia.
In general, surgical closure of patent foramen ovale (PFO) in patients without inter atrial shunt is unnecessary. There is a b association of PFO with paradoxical embolism (PDE) and ischemic cerebral infarction, and reports on patients with PFO related cryptogenic stroke after coronary artery bypass grafting and various surgical cases of heart or lung are being increasingly published in recent years. These findings powered the interest of anesthesiologists, and cardiothoracic surgeons, in spite of the fact that numerous neurologist and cardiologist have greatly payed attention to these events already. This article surveys the current advance of knowledge to delineate the principal mechanism, clinical presentation, diagnostic strategies and treatment options in patients with PFO, atrial septal aneurysm and PDE, and focuses on careful consideration and effective management of patient who was suddenly presented with a cryptogenic stroke or transient ischemic attack followed by cardiothoracic operations.
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.
