Non-valvular atrial fibrillation has a high morbidity. Cox Ⅲ surgery is the gold standard for treating all kinds of atrial fibrillation. However, which needs to be performed with cardiopulmonary bypass (CPB) and the trauma caused by it is severe. It is placed emphasis on minimal invasion, safety and efficacy for contemporary surgery so as to minimally invasive intervention is important in the treating non-valvular atrial fibrillation. Although the results of epicardial ablation with video-assisted thoracoscopic surgery (VATS) are better than that of transcatheter ablation, it also has some disadvantages and shortages under certain circumstance. Epicardial ablation with VATS combined with transcatheter ablation is complemantary which becomes the hot spot for treatment of novalvular atrial fibrillation.
Atrial fibrillation (AF) is difficult to cure for its complex etiology and long disease duration. Heart failure, sudden death and stroke are the main causes for consequent high mortality and morbidity. In recent years, minimally invasive surgery has made rapid progress, not only improved treatment efficiency of traditional Cox Maze procedure but also massively reduced surgical injuries, and has become a preferred treatment strategy for lone AF. Minimally invasive surgery and catheter ablation complement each other, and are likely to open up a new prospect of AF treatment.
ObjectiveTo investigate the efficacy and safety of hybrid perventricular device closure (PVDC) for the treatment of muscular ventricular septal defect (MVSD) in pediatric patients. MethodsWe retrospectively analyzed clinical data of 35 pediatric patients with MVSD who received hybrid PVDC in West China Hospital between 2009 and 2012. There were 16 males and 19 females with their median age of 3.9 years (range, 1 month to 7 years). There were 10 patients with single MVSD, 12 patients with multiple MVSD, 6 patients with other congenital heart defects, and 7 patients with post-surgical residual MVSD. ResultsAmong the 35 patients, immediate complete closure was achieved in 28 (80.0%) patients. Residual shunt was noted in 7 (20.0%) patients. Median device size was 5 mm. Cardiopulmonary bypass was avoided in 19 patients. Two (5.7%) patients died postoperatively due to postoperative heart failure resulted from complex congenital heart defect. All survival patients were followed up for a mean duration of 6 months, and there was no late death. Thirty-one (93.9%) patients had good positioning of the closure devices but no residual shunt. Small residual shunt at the apex was noted in 2 (6.1%) patients. ConclusionHybrid PVDC is an effective treatment for MVSD with relatively high successful rate but low mortality and morbidity, and its short-term results are satisfactory.
ObjectiveTo evaluate the early and mid-term results of robot-assisted coronary artery bypass grafting (RACAB) in the treatment of multi-vessel coronary artery disease (MV-CAD). Methods Patients with MV-CAD who underwent RACAB from April 2018 to December 2021 in our hospital were included. Patients who underwent hybrid coronary revascularization (HCR) which combined RACAB with percutaneous coronary intervention were allocated to a HCR-RACAB group, and patients who underwent multi-vessel RACAB were allocated to a MV-RACAB group. Perioperative and follow-up data were collected and compared between the two groups. Results A total of 102 patients were included, including 81 males and 21 females with a mean age of 61.7±10.8 years. Two (2.0%) patients were transferred to conventional CABG due to sudden ventricular fibrillation and pleura adhesion. In the remaining 100 patients who underwent RACAB, 100 left internal mammary arteries (LIMA) and 46 right internal mammary arteries (RIMA) were harvested with a 100.0% success rate. Besides, all patients undergoing RACAB achieved LIMA/RIMA-left anterior descending branch reconstruction, with an average number of 2.5±0.6 target vessels revascularized by stent or graft. One patient had perioperative myocardial infarction with an outcome of death. The incidence of major perioperative adverse events was 1.0%. There was no perioperative stroke or re-sternotomy for hemostasis. The mean follow-up time was 28.2 months, with a follow-up rate of 99.0% and an overall major adverse cardiac and cerebrovascular event (MACCE) rate of 7.0%, including 3 all-cause deaths (3.0%), 2 strokes (2.0%) and 3 re-revascularizations (3.0%). The HCR-RACAB group had fewer red blood cell transfusion (P=0.030) and intraoperative blood loss (P=0.037) compared with the MV-RACAB group, and there was no statistical difference in the incidence of major perioperative adverse events or MACCE between the two groups during the follow-up period (P>0.05). ConclusionRACAB can be safely applied in the treatment of MV-CAD with good early and mid-term outcomes. High-quality harvesting of LIMA/RIMA and aortic no-touch technique are crucial to achieve these results.
Aortic arch disease is one of the research hotspots and treatment difficulties in the field of aorta, including aortic arch aneurysms, pseudoaneurysm, ulcer, dissection and intramural hematoma. By summarizing the clinical data of the vascular surgery center of Fuwai Hospital of Chinese Academy of Medical Sciences in the past five years and combining with the latest theories of the cutting-edge development of aortic surgery, the authors proposed the "HENDO" concept, including using hybrid technique (H), endovascular repair (Endo) and open surgery (O), properly to treat aortic arch pathologies individually. The authors advocated the establishment of HENDO team and cooperation mechanism in large aortic centers, to eliminate technical shortcomings of a single surgeon by fully mastering the three main technology clusters by teamwork. Accordingly, the best treatment for each patient can be administrated and the survival rate and quality of life can be improved eventually.
Abstract: Objective To summarize the clinical experiences of onestage hybrid operation for treating typeB aortic dissection and aortic aneurysm involving distal aortic arch, explore the indication for this special technique and analyze shortterm followup results. Methods From October 2008 to May 2010, 16 consecutive patients received onestage hybrid operation in Fu Wai Hospital for aortic dissection or aortic aneurysm involving distal aortic arch. There were 12 males and 4 females. Their age ranged from 38.0 to 67.0 years (54.0±9.2 years). There were 14 patients of typeB aortic dissection, 1 patient of thoracic aortic aneurysm involving the aortic arch, and 1 patient of penetrating aortic ulcer. Among them, 10 were acute ones and 6 were chronic ones. Brachiocephalic artery bypass using neck incision with retrograde endovascular stent graft implantation was used. Four patients received bypass from the left common carotid artery to the left subclavian artery; 11 patients underwent bypass from the right common carotid artery to the left common carotid artery; and 1 patient had both of the bypasses. Intensive care unit(ICU) stay, hospital stay， and incidence of complications were closely monitored after operation. Computed tomography(CT) and general condition of the bypass grafts and its blood flow were followed up at three months and one year after operation. Results No death or severe complications occurred perioperatively. All onestage surgeries were technically successful with stent grafts implanted. Angiography during the operation showed 100% patency of all the bypass grafts and no obvious translocation or endoleakage of the stent grafts. One patient had mild paraplegia and recovered soon after treatment. Ventilation time of these patients was 2.010.0 hours (5.3±2.7 hours). The ICU stay was 0.0-2.0 days (1.1±0.4 days) and hospital stay was 4.0-7.0 days (5.3±0.8 days). The expenditure of blood products was 0.0-1 016.5 RMB (134.5±281.8 RMB). All patients were followed up with a followup period of 3.0 to 26.0 months (130±5.1 months). All patients recovered to normal social life. Enhanced CT scanning at three months and one year after operation showed no endoleakage or translocation of the stent grafts and 100% patency of the bypass grafts. There was no obvious change of the distal part of the dissection except some thrombosis formation in nine patients. Conclusion Onestage hybrid operation is safe and effective in shortening the duration of the operation and hospital stay, reducing the surgical trauma and sufferings of the patients, and lowering the risk of staged operations with satisfactory shortterm results. This special technique may expand the indications of simple endovascular repair. The mid and longterm results still need to be followed up.
