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.
Objective To introduce the application of transcatheter closure of multi-fenestrated atrial septal defect (ASD) via femoral vein under ultrasound guidance with amplatzer cribriform occluder (ACO) and atrial septal defect occluder (ASDO), as well as to assess its feasibility, effectiveness and safety. Methods The clinical data of 48 patients with fenestrated ASD occluded via femoral vein under ultrasound guidance from December 2015 to May 2018 in our hospital were retrospectively analyzed, including 17 males and 31 females, aged 10 months to 51 years, an average of 11.50±13.86 years, and weighting 6-79 (27.00±20.14) kg. Among 48 patients with fenestrated ASD, 12 patients had double-foramen and 13 atrial septal aneurysm combined with defects and 23 multi-foramen. All patients underwent transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE) to complete the closure of fenestrated ASD. Ultrasound, electrocardiogram and chest X-ray were reviewed the next day after surgery to evaluate the curative effect. Results Forty-eight patients with ASD were treated with 49 occluders, due to one patient with two occluders. There were 29 ASDO (8-26 mm) and 20 ACO (18-34 mm). During the operation, TTE/TEE examination showed that 48 patients were completely occluded, 13 patients showed fine bundle shunt in the unreleased push notification rod, and 9 patients had fine bundle shunt after the release of push notification rod. Fine bundle shunt was found in 8 patients 24 hours after operation, and microshunt was found in 3 patients 1 year after operation. All the patients were followed up. The occluder position was good. The right heart was reduced in different degrees, and the X-ray showed that the pulmonary blood was reduced in different degrees. No arrhythmia was found by electrocardiogram after operation. Conclusion It is a safe and effective method to use ACO and ASDO to occlude ASD through femoral approach under ultrasound guidance.
Surgical treatment of atrial septal defect (ASD) mainly includes occlusion or repair under cardiopulmonary bypass. Surgical treatment of atrial fibrillation includes transcatheter radiofrequency ablation or Maze surgery under cardiopulmonary bypass. There are many treatments for ASD patients combined with atrial fibrillation, but each has its own advantages and disadvantages. We reported an ASD patient combined with atrial fibrillation treated by totally endoscopic "one-stop" radiofrequency ablation and simultaneous transthoracic ASD occlusion of atrial fibrillation, with good postoperative results.
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.
ObjectiveTo compare the short-term outcomes of surgical repair for atrial septal defect (ASD) with a robotic (da Vinci Si) approach versus a conventional open procedure.MethodsClinical data of 140 patients undergoing ASD closure in the First Affiliated Hospital of Anhui Medical University from January 2016 to May 2020 were retrospectively analyzed. The patients were divided into a robotic group and a sternotomy group according to different surgical methods. In the robotic group, there were 67 patients including 20 males and 47 females at a median age of 40.0 (25.0) years, and in the sternotomy group there were 73 patients including 23 males and 50 females at a median age of 41.0 (29.0) years. Multivariate linear regressions were used to produce risk-adjusted analysis of pertinent clinical characteristics. Kaplan-Meier analysis was performed to compare the speed of sternotomy versus robotic group returning to exercise or daily life.ResultsRobotic-assisted surgery was associated with significantly shorter 24 h postoperative drainage volume [220.0 (210.0) mL vs. 345.0 (265.0) mL, P<0.001], mechanical ventilation [6.0 (11.0) h vs. 8.0 (11.0) h, P=0.024], intensive care unit length of stay (LOS) [19.0 (19.0) h vs. 22.0 (25.0) h, P=0.005], postoperative hospital LOS [9.0 (5.0) d vs. 10.0(6.0) d, P=0.003], and a lower rate of perioperative blood transfusion (28.36% vs. 84.93%, P<0.001). After controlling for patient comorbidity in the multiple regression model, there remained a trend toward decreased 24 h postoperative drainage volume (β=–115.30, 95%CI–170.78 to –59.82, P<0.001), mechanical ventilation (β=–4.96, 95%CI –8.33 to –1.59, P=0.004) and postoperative hospital LOS (β=–2.31, 95%CI –3.98 to –0.63, P=0.007) in the robotic group. Kaplan-Meier analysis revealed that patients returned to exercise or daily life earlier in the robotic group [35.0 (32.0) d vs. 90.0 (75.0) d, P<0.001].ConclusionClosure of ASD can be performed safely and effectively via robotic approach. And the minimally invasive technique is beneficial to postoperative recovery.
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 evaluate the efficacy and safety of transthoracic minimally invasive occlusion operation for the treatment of congenital atrial and ventricular septal defects. Methods The clinical data of 88 patients who underwent surgical occlusion operation from December 2015 to February 2017 were summarized. There were 52 males and 36 females, aged 6.8±7.5 years ranging from 1.6 to 24.0 years. All the patients were followed up by ultrasound and electrocardiogram at postoperative 3, 6 and 12 months. The efficacy of minimally invasive thoracotomy was analyzed by statistical methods. Results The patients were followed up for 3-15 (6.8±2.3) months, and the follow-up rate was 92.0%. Ultrasound showed occluder fixed well and no residual shunt, valve regurgitation, thrombosis or other complications occurred. The heart was reduced, the ejection fraction was greater than 55%, and heart function rating for all patients was grade Ⅰ. Conclusion Transthoracic mini-invasive surgical occlusion of atrial and ventricular septal defects is safe and effective. The short and middle-term effect is satisfying. It can be widely used in clinical, but multi-center and long-term follow-up and assessment still need to be carried out.
Reoperation due to degenerated bioprostheses is an important factor of high-risk thoracic surgeries. In 2020 ACC/AHA guideline, Valve in Valve (ViV) was recommended for high-risk patient instead of surgical mitral valve replacement. This report described a 77-year-old male patient with a failed mitral bioprosthetic valve, evaluated at high risk of surgery, received a transvenous, transseptal transcatheter mitral valve replacement (TMVR). Tracheal intubation was removed at CCU 3 h after surgery without discomfort such as polypnea. The patient was transferred out of the CCU and discharged on the 3rd day. Compared with transapical access, transvenous transseptal access was less invasive, with shorter duration in CCU and hospitalization.
ObjectiveTo observe the short-term therapeutic outcomes of atrial septal defects (ASD) repair using on-pump beating-heart technique assisted by robotic surgery system (Da Vinci Si) or thoracoscopy.MethodsClinical data of 50 patients undergoing ASD repair at the First Affiliated Hospital of Anhui Medical University from January 2015 to December 2018 were retrospectively analyzed. According to the different surgical methods, patients were divided into a robot group and a total thoracoscopy group. In the robot group, there were 35 patients including 11 males and 24 females, at an average age of 42.1±16.8 years, and in the total thoracoscopy group there were 15 patients including 8 males and 7 females at an average age of 38.4±10.9 years. During follow-up, the left ventricular ejection fraction, left and right atrial diameter, and right ventricular end-diastolic diameter in the cardiac Doppler echocardiography were recorded. The operation time, extracorporeal circulation time, ventilation time, postoperative ICU stay, postoperative hospital stay, perioperative pleural drainage and early complications were compared between the two groups.ResultsIn the perioperative period, the robot group had less operation time (3.8±0.3 h vs. 6.1±1.4 h), extracorporeal circulation time (72.3 ± 10.4 min vs. 139.1 ± 32.8 min), ventilation time (5.5±1.2 h vs. 9.5 ± 2.1 h), postoperative hospital stay (6.7±0.5 d vs. 9.8 ± 0.6 d) and thoracic drainage (253.4±26.8 mL vs. 289.3 ± 29.5 mL) than the total thoracoscopy group (P<0.05), while the postoperative complications were not statistically significant between the two groups (P>0.05). All patients were reviewed by color Doppler ultrasound at 1 month after operation. The postoperative dilated right atrium, right ventricle and left atrium were smaller than those before surgery.ConclusionFor patients undergoing ASD repair, robot-assisted and total thoracoscopy can achieve good results, but the robot group has more advantages in terms of operation time, extracorporeal circulation time, ventilation time, postoperative hospital stay and thoracic drainage.
