摘要:目的:分析微创外科室间隔缺损(ventricular septal defect,VSD)封堵失败原因,以期提高术前超声心动图筛查水平。方法:回顾性分析25例微创外科VSD封堵失败改行修补术病例,对比超声表现及手术所见,归纳总结产生并发症的原因。结果:残余分流与VSD假性膜部瘤右室面具有多个出口和低估VSD大小密切相关;VSD合并主动脉瓣右冠瓣脱垂是主动脉瓣反流的主要原因;封堵器移位与低估VSD大小且使用偏心封堵器有关;原有三尖瓣反流加重和发生Ⅲ度房室传导阻滞VSD均位于隔瓣下方;封堵失败组较封堵成功组缺损偏大,差异具有统计学意义(Plt;0.05)。结论:超声心动图对VSD及其毗邻结构的细致评估,有助于严格适应证,提高手术成功率。 Abstract: Objective:To analyze the failure of perventricular closure of ventricular septal defect (VSD), in order to improve the preoperative echocardiography examination. Methods: Twentyfive cases underwent surgical repair after failure of perventricular closure of VSD were included in this study. With combination of echocardiographic and surgical findings, retrospective analysis of the failure of perventricular closure of VSD were attempted to summarize the cause of complications.Results: Residual ventricular communication was due to underestimation of size of VSD and pseudomembranous aneurysm resulting in multiple outlets of VSD on the right ventricle side; preoperative prolapse of rightcoronary cusp was the main reason for mild or greater than mild aortic valve regurgitation after eccentric device closure of VSD; Underestimation of the size of VSD and using eccentric occluder device were responsible for the displacement of VSD occluder device. Postoperative aggravated tricuspid regurgitation and Ⅲ°atrialventricular block (AVB) were attributed to VSDs located under the septal leaflet of tricuspid valve. The size of VSD in group of failed perventricular device closure of VSD was larger than that in group of successful device closure of VSD,and the difference was significant(Plt;0.05). Conclusion: Echocardiography vividly reveals VSD and adjacent structures, which should be used in accessing the anomaly and defect and formulating surgical plans to reduce surgical morbidity and mortality.

After two decades of development, transcatheter left atrial appendage closure has emerged as a safe and effective intervention for stroke prevention in patients with atrial fibrillation. In 2024, significant advancements were made in the field of left atrial appendage closure in terms of evidence-based medicine, device research and development, and guideline consensus. The annual report on transcatheter left atrial appendage closure systematically reviews global academic progress in 2024, encompassing newly published clinical evidence, recently developed occlusion devices, and updated international guidelines/consensus statements. In the future, the development direction of transcatheter left atrial appendage closure mainly includes expanding surgical indications, optimizing imaging assistance technology, improving closure device design, and exploring individualized strategies for postoperative antithrombotic therapy.
Objective To compare the effects of transthoracic device closure and surgical closure on ventricular septal defect systemically. Methods A systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Chinese Clinical Trial Register, ClinicalTrials. gov and Wanfang Database up to July 31, 2016. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted using RevMan 5.0 and Stata 14.0 software. Results Eleven studies were identified, including 5 RCTs and 6 cohort studies involving 2 504 patients. For success rate, there was no statistical difference between the transthoracic closure group and the surgical closure group in RCT (RR=0.99, 95%CI 0.96 to 1.03, P=0.70); the success rate in the transthoracic closure group was lower than that in the surgical closure group in the cohort study (OR=0.21, 95%CI 0.08 to 0.55, P=0.002). Both results of RCTs and cohort studies showed that compared with surgical closure, transthoracic device closure reduced duration of the operation (RCT MD=–79.38, 95%CI –95.00 to –63.76, P<0.000 01; cohort studyMD=–66.26, 95%CI –71.20 to –61.31, P<0.000 01) and hospital stay (RCTMD=–2.10, 95%CI –2.65 to –1.55, P<0.000 01; cohort studyMD=–3.99, 95%CI –6.03 to –1.94, P=0.000 1), and the patients with blood transfusion (RCT RR= 0.04, 95%CI 0.01 to 0.11, P<0.000 01; cohort studyOR=0.01, 95%CI 0.00 to 0.13, P=0.001). In the transthoracic closure group the risk of postoperative arrhythmia reduced (RCT RR=0.20, 95%CI 0.13 to 0.32, P<0.000 01; cohort studyOR=0.46, 95%CI 0.31 to 0.67, P<0.000 1). In the transthoracic closure group a higher postoperative valvular regurgitation risk in RCT induced (RR=1.45, 95%CI 1.07 to 1.96, P=0.02) and the rate of postoperative valvular regurgitation in cohort study reduced (OR=0.43, 95%CI 0.20 to 0.92, P=0.03). However, there was no statistical difference in postoperative residual shunt (RCT RR=0.96, 95%CI 0.57 to 1.62, P=0.89; cohort study OR=0.52, 95%CI 0.12 to 2.25, P=0.38). Conclusion Transthoracic device closure can shorten duration of the operation, hospital stay and reduce the patients with blood transfusion and post- and intraoperative arrhythmia risk. Therefore, transthoracic device closure may be a better approach for some ventricular septal defect patients.
Doubly committed sub-arterial ventricular septal defect (VSD) is a unique type of VSD which is located beneath both the aortic and pulmonary valve. Open-heart repair is traumatic especially for pediatric patient while trans-catheter device closure is also not suitable for this type of VSD. Minimally invasive per-ventricular device closure has been introduced as an alternative method in the treatment of doubly committed VSD with encouraging results. In the review, we will illustrate the surgical technique as well as perioperative management strategy as for this technique in treating doubly committed VSD.
Objective To explore the feasibility of transcatheter closure of congenital heart disease (CHD) under the guidance of transthoracic echocardiography (TTE). Methods A total of 37 patients with CHD who received transcatheter closure under the guidance of transthoracic echocardiography from November 2013 through November 2015 in our hospital were recruited. There were 15 males and 22 females, aged 1 to 16 years. Among them 32 patients suffered atrial septal defect and 5 patients had patent ductus arteriosus. The transcatheter closure of CHD was performed under the guidance of TTE. The patients underwent echocardiography follow-up at one, three and six months after surgery. Results Closure devices were successfully implanted in 37 patients under TTE guidance. The procedure was simple and safe. During the follow-up, no severe complication such as valvular injury, pericardial effusion, residual shunt and peripheral vascular injury occurred. Conclusion Transcatheter closure of CHD under TTE guidance is a feasible method and worth further clinical application.
ObjectiveTo explore the clinical characteristics and improve the knowledge of diagnosis and treatment of complex pulmonary arteriovenous fistula (PAVF) as well as enrich the experience of diagnosis and treatment of the disease.MethodsA retrospective analysis of pathogenetic process clinical manifestations, imaging features and diagnosis and treatment was conducted on one case of complex PAVF. The literature review was carried out with " complex pulmonary arteryovenous fistula (malformation)” as the research terms in English and Chinese respectively in CNKI, WanFang and PubMed database. Search time ranged from January 1997 to April 2018, and the literature was screened and reviewed.ResultsThe patient was a 47-year-old female complained of recurrent epistaxis for 40 years, intermittent hemoptysis for 20 years, headache, dizziness, chest pain, chest tightness for 4 years and the symptoms were aggravated by 3 months, visiting this hospital on January 23, 2018. Pulmonary CT angiography revealed multiple nodules in internal and external segment and outer basal segment of right lung, anterior basal segment and outer basal segment of left lung. CT enhanced scan showed that the thickened pulmonary artery was connected with the above lesion, and the edge was accompanied by large draining veins. Pulmonary artery revascularization showed complex PAVF abnormal branches. The diagnosis was complex PAVF, and interventional embolization therapy was carried out and curative effect was satisfactory during the follow-up. A total of 6 literatures were reviewed in above-mentioned databases, including 4 Chinese literatures and 2 English literatures, containing 10 patients, including 8 males and 2 females, with an average age of (9.7±7.0) years. Most of the clinical manifestations were shortness of breath after exercise, cyanosis and hemoptysis and all patients were cured and discharged after interventional embolization treatment except for 1 patient refused treatment.ConclusionsComplex PAVF is a very rare pulmonary vascular malformation. The clinical manifestations mainly include hypoxemia, dyspnea, hemoptysis, and the preferred treatment is interventional embolization, which has a satisfactory clinical effect at a short-term follow-up.
Patients with atrial fibrillation complicated with kidney disease have a high risk of stroke and bleeding, and have some limitations or contraindications to oral anticoagulants. Left atrial appendage closure has been used as an alternative to oral anticoagulation in patients with atrial fibrillation, but its efficacy and safety in patients with atrial fibrillation and chronic kidney disease need to be further confirmed. This paper intends to review the research progress of left atrial appendage occlusion in patients with atrial fibrillation complicated with chronic renal insufficiency.
