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 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.
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.
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 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 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 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.
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 explore the key points, indications and safety of trans-jugular transcatheter closure of atrial septal defect (ASD) in infants.MethodsThe clinical data of 53 infants with ASD from January 2017 to May 2019 in our hospital were retrospectively reviewed. There were 20 males and 33 females with the age of 1.2 (0.5-2.9) years, and body weight of 9.0 (6.8-10.6) kg. The ASD diameter was 9.8 (8.0-14.0) mm. Thirty-one patients were treated under the guidance of transesophageal ultrasound (TEE), and the other 22 patients under the guidance of transthoracic echocardiography (TTE). We used the steerable curved sheath through the internal jugular vein under the guidance of echocardiography, and the average occluder size was 13.5±4.5 mm.ResultsAll of the 53 patients were successfully occluded, and none of them changed to radiation-guided or transthoracic surgery. Postoperative hospital stay was 3.35±0.70 d. There was no complication such as peripheral vascular injury, occluder malposition or displacement, serious arrhythmia or pericardial effusion. The patients were followed up for 14.3±5.1 months without arrhythmia, residual shunt, occluder malposition or displacement or thrombus.ConclusionEchocardiography-guided trans-jugular closure of ASD for infants with low weight and large ASD shunt or patients with inferior vena cava abnormalities not suitable for femoral vein treatment, not only overcomes the radiation risk of radiation guidance, but also maintains the advantages of minimal invasiveness and safety, providing a new treatment option for such patients.
Atrial septal defect (ASD) is a congenital heart disease that causes blood communication between the left and right ventricles due to partial atrial septal tissue defects, accounting for about 13% of all heart malformations. Secondary ASD is the most common type of ASD and can generally be treated with minimally invasive closure. At present, the commonly used minimally invasive methods in clinical practice mainly include X-ray-guided percutaneous occlusion, transesophageal ultrasound-guided transthoracic occlusion and ultrasound-guided percutaneous occlusion. This review focuses on the basic research process of occluder materials, and advantages and disadvantages of three different surgical methods.
