Objective To explore the safety and efficacy for patients with central airway-pleural fistula (APF) treated by atrial septal defect (ASD) occluder. Methods This was a retrospective study. Between January 2017 and October 2021, a total of 16 patients with postoperative APF were treated with ASD occluder through bronchoscope under local anesthesia combined with sedation. The efficacy and complication were recorded during and after the procedure. Results Sixteen patients were recruited in this study and the average age was 60.7 years (range 31 - 74 years). The main etiology for APF was lobectomy/segmentectomy (n=12), pneumonectomy (n=2), radical esophagectomy (n=1) or decortication for chronic empyema (n=1). Totally, 4 fistulas were located in right main bronchus, 3 in left main bronchus, 3 in right upper bronchus, 1 in right middle bronchus, 2 in right lower bronchus and 3 in left upper bronchus. The median diameter of APF was 7.8 mm (ranged from 4 to 18 mm) and the median diameter of ASD occluder inserted was 10.0 mm (ranged from 6 to 20 mm). Successful occlusion of APF was observed in 15 patients (15/16) and 1 patient died of multiple organ failure caused by bacteremia 14 days after the procedure. Fourteen patients were recruited for long-term follow-up, on a median follow-up period of 16.2 months (ranged from 3 to 46 months). There were 12 patients of complete remission and 2 patients of partial remission and only one patient took a second operation due to the enlargement of fistula and translocation of occluder. At follow-up, 4 patients died and the reasons were directly related to the primary etiology, and no patient died due to APF recurrence. Conclusion Endobronchial closure of central APF using ASD occluder is a minimally invasive but effective modality of treatment with satisfactory long-term outcome.
Objective To explore the technique of performing minimally invasive Cox Maze Ⅳ procedure by bipolar clamp through right lateral minithoracotomy for atrial septal defect (ASD) combined with atrial fibrillation (AF) in adults. Methods Thirty-five patients (21 males, 14 females with age ranging from 45 to 73 years) with ASD and persistent or long-standing persistent AF received minimally invasive Cox Maze Ⅳ procedure and ASD closure from August 2012 to April 2016 at Department of Cardiothoracic Surgery, Xinhua Hospital. Diameter of left atrium ranged from 39 to 60 mm and left ventricle ejection fraction (LVEF) ranged from 48% to 62%. Diameter of ASD ranged from 20 to 35 mm. Cox-maze Ⅳ procedure was performed through right minithoracotomy entirely by bipolar radiofrequency clamp. Then, mitral or tricuspid valvuloplasty and surgical ASD closure was performed through right minithoracotomy. Results All patients successfully underwent this minimally invasive surgery. No patient needed conversion to sternotomy. The mean cardiopulmonary bypass time was 120.1±14.1 min. The mean aortic cross-clamp time was 79.5±12.2 min. There was no early death or pacemaker implantation perioperatively. The average length of hospital stay was 10.1±2.7 d. At a mean follow-up of 22.8±12.2 months, sinus rhythm was restored in 32 patients (32/35, 91.4%). Cumulative maintenance of normal sinus rhythm without AF recurrence at 2 years postoperatively was 89.1%±6.0%. Conclusion The minimally invasive Cox Maze Ⅳprocedure performed by bipolar clamp through right minithoracotomy is safe, feasible, and effective for adult patients with ASD combined with AF.
ObjectiveTo compare the effects of transthoracic device closure and traditional surgical repair on atrial septal defect systemically.MethodsA systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Wanfang Database up to July 31, 2018 to identify trials according to the inclusion and exclusion criteria. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted by RevMan 5.3 and Stata 12.0 software.ResultsThirty studies were identified, including 3 randomized controlled trials (RCTs) and 27 cohort studies involving 3 321 patients. For success rate, the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.34, 95%CI 0.16 to 0.69, P=0.003). There was no statistical difference in mortality between the two groups (CCT, OR=0.43, 95%CI 0.12 to 1.52, P=0.19). Postoperative complication occurred less frequently in the transthoracic closure group than that in the surgical repair group (RCT, OR=0.30, 95%CI 0.12 to 0.77, P=0.01; CCT, OR=0.27, 95%CI 0.17 to 0.42, P<0.000 01). The risk of postoperative arrhythmia in the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.56, 95%CI 0.34 to 0.90, P=0.02). There was no statistical difference in the incidence of postoperative residual shunt in postoperative one month (CCT, OR=4.52, 95%CI 0.45 to 45.82, P=0.20) and in postoperative one year (CCT, OR=1.03, 95%CI 0.29 to 3.68, P=0.97) between the two groups. Although the duration of operation (RCT MD=–55.90, 95%CI –58.69 to –53.11, P<0.000 01; CCT MD=–71.68, 95%CI –79.70 to –63.66, P<0.000 01), hospital stay (CCT, MD=–3.31, 95%CI –4.16, –2.46, P<0.000 01) and ICU stay(CCT, MD=–10.15, 95%CI –14.38 to –5.91, P<0.000 01), mechanical ventilation (CCT, MD=–228.68, 95%CI –247.60 to –209.77, P<0.000 01) in the transthoracic closure group were lower than those in the traditional surgical repair group, the transthoracic closure costed more than traditional surgical repair during being in the hospital (CCT, MD=1 221.42, 95%CI 1 124.70 to 1 318.14, P<0.000 01).ConclusionCompared with traditional surgical repair, the transthoracic closure reduces the hospital stay, shortens the length of ICU stay and the duration of ventilator assisted ventilation, while has less postoperative complications. It is safe and reliable for patients with ASD within the scope of indication.
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 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.
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 assess the feasibility and safety of percutaneous transcatheter closure of atrial septal defect (ASD) guided by transthoracic echocardiography (TTE) in outpatients.MethodsFrom December 2016 to June 2018, 50 simple ASD patients underwent TTE-guided transcatheter closure in the outpatient operating room of our hospital (a TTE group) including 22 males and 28 females at the age of 16-48 (27.40±6.95) years. Fifty patients with simple ASD treated with the guidance of conventional fluoroscopy during the same period were treated as a control group, including 22 males and 28 females at the age of 15-48 (28.58±6.96) years. Both groups were re-examined by TTE during follow-up at 1 month, 3 months, 6 months and 1 year.ResultsThe mean age, body weight, the size of ASD and occluder and success rate had no statistical difference between the two groups (P>0.05). Compared with the control group, the TTE group had significantly lower mean operation time (P<0.01) and less cost (P<0.01) since patients need not to be hospitalized. No related complications were found in the TTE group during follow-up.ConclusionPercutaneous transcatheter closure of ASD guided by TTE appears safe and effective for outpatients, and can significantly reduce the cost.
