Abstract： Objective To optimize surgical treatment for children with patent ductus arteriosus （PDA） and mitral regurgitation （MR） and evaluate its midterm to longterm outcome in terms of MR. Methods Between Jan. 2008 and Jan. 2011， 25 children with PDA and MR underwent surgical treatment in Shanghai Children’s Medical Center. There were 14 male patients and 11 female patients with average age of 26.36±40.75 （1.72-142.83）months and average weight of 8.98±6.85 （3.80-36.00） kg. The average diameter of PDA was 7.84±3.10 （3-15）mm. There were 22 children with duct-type PDA and 3 children with window-type PDA. There were 5 children with severe MR， 18 children with moderate MR， and 2 children with mild MR. Except one child with mitral stenosis who underwent PDA ligation plus mitral valvuloplasty supported with cardiopulmonary bypass， all other 24 children only underwent PDA ligation through left posterolateral thoracotomy without any management for the mitral valve. Results There was no in-hospital death. The average ventilation time in ICU was 6.70±4.39 （3-24） hours. Except one child was reintubated because of asthma， all other children recovered uneventfully without any postoperative complication. All the 25 children were followed up for 329.23±288.39 （29-967） days. During follow-up， 23 children （92.00%） had their MR level ameliorated in different degree. Preoperative severe MR in 5 children changed into moderate MR in 2 children and mild MR in 3 children. Preoperative moderate MR in 16 children changed into none MR in 5 children, trivial MR in 5 children and mild MR in 6 children. Preoperative mild MR in 2 children changed into none MR in 1 child and trivial MR in another child. Two children with preoperative moderate MR had no improvement during follow-up. Conclusion For infants and children with PDA and MR， conservative treatment strategy should be carried out. Simple PDA ligation can provide satisfactory clinical outcome， which may also avoid negative complications including myocardial injury caused by cardiopulmonary bypass.
目的 总结单心室瓣膜反流的外科治疗经验，观察治疗效果。 方法 回顾性分析2006年7月至2012年1月上海交通大学医学院附属新华医院61例单心室患者的临床资料，其中男36例，女25例；手术年龄2个月至 20岁；体重2～58 kg。右心室型41例，左心室型13例，未定型型7例。根据瓣膜反流程度不同分为3组，无/微量反流组：28例，瓣膜未行处理；轻/中度反流组：21例，瓣膜未行处理；重度反流组：12例，手术同期行瓣膜成形。收集所有患者住院及随访资料，分析轻/中度反流组、重度反流组瓣膜反流变化趋势，以及影响瓣膜反流的因素。结果 住院死亡5例，住院死亡率8.2% （5/61）。重度反流组患者行瓣膜成形术后反流程度较术前明显减轻（由术前4.00级下降至术后2.08级）。随访56例，随访时间6～38个月，重度反流组随访10例，随访期间死亡2例，其余8例中重度反流2例，中度反流3例，轻度反流2例，微量反流1例；瓣膜反流程度增加趋势明显（由术后平均2.08级增加至平均2.75级）。轻/中度反流组随访19例，随访中无死亡，其中反流程度增加至重度3例（原1例轻度反流，2例中度反流），反流程度由轻度增加至中度3例，瓣膜反流程度由术后平均2.33级增加为平均2.58级。轻/中度反流组瓣膜反流增加率与无/轻微反流组比较差异无统计学意义（瓣膜反流增加率为31.5% vs. 19.2%，χ2=0.36，P=0.55）。单因素分析结果显示，瓣膜反流增加者在随访过程中心功能较瓣膜反流无变化或减轻者明显降低（术后左心室射血分数53.11%±5.61% vs. 59.65%±3.32%，t =-5.49，P=0.00），而左心室舒张期末容积较瓣膜反流无变化或减轻者明显增加（t =2.58，P=0.01）。 结论 单心室合并重度瓣膜反流行瓣膜成形术近期效果较好，但随着心功能下降、心室扩张，瓣膜反流程度加重趋势明显；轻/中度瓣膜反流可暂不进行处理，但部分患者瓣膜反流有增加趋势，提示应注重术后随访。
Abstracts： Objective To summarize clinical experience and surgical outcomes of congenital coronary arterial fistula （CAF）. Methods We retrospectively analyzed clinical records of 12 patients （6 males, 6 females）, aged from 4 to 77 （50.90±23.8） years, who underwent surgical repair of CAF in Nanjing First Hospital between February 2005 and June 2011. There were 3 CAF patients associated with coronary artery aneurysms, one with patent foramen ovale and 2 with coronary artery disease （CAD）. One CAD patient had concomitant severe aortic valve stenosis. One patient underwent surgical repair without cardiopulmonary bypass （CPB） and 11 patients underwent surgery under CPB, among whom 3 patients underwent surgery with beating heart. One patient underwent concomitant aortic valve replacement and coronary artery bypass grafting.?Results?All the patients recovered uneventfully. Operation time was 151.25±42.65 min （ranging from 90 to 245 min）, cardiopulmonary bypass time was 65.06±29.16 min （ranging from 31 to 116 min）, mean aortic cross-clamping time was 43.00±33.41 min （ranging from 18 to 97 min） and postoperative hospital stay was 12.50±1.45 d （ranging from 10 to 15 d）. There was no early or late death. All the patients were followed up from 4 months to 6 years and no patient had symptom recurrence, myocardial ischemia or residual fistula during the follow-up. Conclusions All CAF patients should be surgically treated once diagnosis are made with satisfactory surgical outcome.
Objective To summarize clinical characteristics and treatment results of adult patients with coronary heart disease and ventricular aneurysm，and evaluate surgical outcomes. Methods Clinical data of 86 adult patients with coronary heart disease and ventricular aneurysm who underwent surgical treatment in Fu Wai Hospital from January 2011 to November 2012 were retrospectively analyzed. There were 70 male and 16 female patients with their average age of 57.7±10.6 years and average body weight of 71.7±10.5 kg. Preoperative echocardiography or left ventriculography showed left ventricular thrombus in 22 patients. Coronary angiography showed 47 patients with 3 vessel disease，29 patientswith 2 vessel disease，and 10 patients with single vessel disease. Sixteen patients underwent direct linear suturing of theaneurysm off pump，39 patients underwent simple linear suturing under cardiopulmonary bypass，15 patients received endoventricular purse-string reconstruction，and 16 patients received endoventricular purse-string reconstruction and patch plasty. Three patients underwent reexploration for bleeding. Sixty-four patients received concomitant coronary artery bypass grafting（CABG）. Results Postoperatively 2 patients（2.3%） died of refractory ventricular fibrillation and multiple organ dysfunction syndrome respectively. Patients undergoing concomitant CABG received 2.3±1.2 grafts on the average. Seventy-eightpatients （92.9%） were followed up for 2-24 months after discharge. During follow-up，patients’ angina symptoms significantlyresolved，heart function improved in varying degrees，and no new sign of myocardial ischemia was found on electrocardiogram.Left ventricular ejection fraction （LVEF） was significantly higher than preoperative LVEF（51%±7% vs. 41%±9% ，t=6.20，P=0.00），and left ventricular end-diastolic diameter （LVEDD） was significantly smaller than preoperative LVEDD （54.2±6.2 mm vs. 56.0±6.8 mm，t=4.60，P=0.00） . Conclusion Ventricular aneurysm repair and concomitant CABG （or ventricular septal perforation repair，mitral valvuloplasty et al） are positive and effective treatment strategies for postinfarction ventricular aneurysm. Satisfactory clinical outcomes can be achieved by individualized treatment based on appropriate surgical strategies according to the size of ventricular aneurysm.
