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 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.
ObjectiveTo evaluate the efficacy and safety of a novel wire for echo-guiding percutaneous atrial septal defect (ASD) closure.MethodsTwenty sheep were randomly divided into two groups, an experimental group and a control group (n=10 in each group). In both groups, an animal model of ASD was established by transthoracic balloon dilatation, and percutaneous closure of atrial septal defect was finished only by echography guiding. The total procedure time, passing time (time needed for the guide wire to enter the left atrium), frequency of delivery sheath dropping into right atrium, frequency of arrhythmias and rate of complications were compared between the two groups.ResultsASD model was uneventfully established in all animals. ASD devices were successfully implanted in all sheep. Compared with the control group, the experimental group had significantly less mean procedure time and mean passing time, lower frequency of guide wire dropping into right atrium and frequency of atrial and ventricular premature contractions, respectively (15.36±4.86 min vs. 25.82±7.85 min, 2.69±0.82 min vs. 5.58±3.34 min, 0% vs. 40.0%, 4.41±2.61 vs. 9.60±3.68, 0.75±0.36 vs. 1.34±0.68; all P<0.05) . Two groups did not have serious complications within postoperative one week.ConclusionThe novel wire system is not only safe and effective in the treatment of ASD occlusion, but also easy to operate.
Objective
To analyze the safety and effectiveness of ultrasound-guided thoracoscopic atrial septal defect (ASD) closure.
Methods
We prospectively collected the clinical data of 12 patients with ASD treated by ultrasound-guided thoracoscopic ASD closure in Fuwai Hospital from January to September 2017. The characteristics of the patients' ASD and operation, operation safety and effectiveness, postoperative complications and follow-up results were analyzed.
Results
Among the 12 patients, 10 were successfully treated with ultrasound-guided thoracoscopic ASD closure. Two patients switched to ASD repair under thoracoscopy-assisted cardiopulmonary bypass. The size of the ASD was 17-40 (27.22±8.97) mm and the size of the occluder was 36 (30-42) mm. The average postoperative length of hospital stay was 6 days. There were no complications such as arrhythmia, bleeding and pericardial effusion after operation. The average follow-up was 6 (3-10) months after the operation. During the follow-up, no Ⅲ-degree conduction block, occluder dislocation, residual shunt or cardiac pericardial effusion was found.
Conclusion
Ultrasound-guided thoracoscopic ASD closure is a minimally invasive, safe and effective treatment. This technique provides a new minimally invasive surgical option for patients with large defect diameter and poor edge condition.
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.
Objective
To evaluate long-term outcomes of surgical closure of atrial septal defect (ASD) and combined surgical radiofrequency ablation for atrial fibrillation (AF).
Methods
A total of consecutive 15 patients with ASD undergoing surgical closure of ASD and combined surgical radiofrequency ablation in our department between March 2003 and April 2015. There were 7 males and 8 females at an average age of 47.1±10.8 years ranging from 16 to 62 years. Retrospective analysis and follow-up were performed to evaluate long-term success rate freedom from AF after surgery.
Results
All patients recovered and discharged, and no patient suffered death or stroke. The duration of follow-up was from 3 to 136 months for all patients. Success rate freedom from AF at 1, 3, 5 and 10 years was 81.3%, 75.0%, 68.8% and 61.1%, respectively. During follow-up, there was no death or stroke. One patient required permanent pacemaker implantation.
Conclusion
Concomitant surgical closure of ASD and biatrial radiofrequency ablation is safe and effetive with better long-term outcomes. It is necessary to perform the two procedures together for ASD patients.
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.
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.
