ObjectiveTo summarize the minimally invasive experiences and medium-long-term results of perventricular device closure of ventricular septal defects (VSD) under transesophageal echocardiography (TEE) guidance.MethodsWe retrospectively analyzed the clinical data and medium-long-term follow-up results of 783 patients who undertook perventricular device closure under TEE guidance in Dalian Children’s Hospital from July 2011 to January 2020, in which perimembrane VSD were found in 598 patients, VSD with aortic valve prolapse in 135 patients and muscular VSD in 2 patients. There were 463 males and 320 females at age of 5 months to 13 years with average age of 3.3±1.2 years, and body weight of 5.9-51.0 (15.9±8.3) kg. The left ventricular defect diameter of the VSD ranged from 5.0 to 11.0 mm, with an average of 6.3±1.2 mm. The right ventricular defect diameter of the VSD ranged from 2.3 to 8.0 mm, with an average of 4.3±0.9 mm.ResultsThe procedures were completed successfully in 753 patients. The device of 1 patient (0.1%) fell off and embedded in the right pulmonary artery after the operation, and the occluder was taken out and the VSD was closed with cardiopulmonary bypass (CPB) in the secondary operation. One patient (0.1%) appeared Ⅲ degree atrioventricular block in 2 years after operation. The device was taken out and VSD was closed with CPB in the secondary operation, and the patient gradually reached to sinus rhythm in post-operation. Eight patients (1.1%) presented delayed pericardial effusion in 1 week after operation, and were cured by pericardiocentesis with ultrasound-guided. Symmetric occluders were used in 580 patients, eccentric occleders were used in 171 patients and muscular occluders were used in 2 patients. The follow-up time was 9 months to 9 years. The rate of loss to follow-up was 96.7% (704/728). No residual shunt, occlude-loss or arrhythmia was found during follow-up. Conclusion The minimally invasive penventricular device closure of VSD guided by TEE is safe and availabe. Medium-long-term follow-up results are satisfactory, it is worthy of clinical promotion, and longer term follow-up is still needed.
ObjectiveTo evaluate the effectiveness of mitral valve repair for mitral regurgitation. MethodsWe retrospectively analyzed the clinical data of 47 patients underwent mitral repair in General Hospital of Ningxia Medical University between January 2010 and June 2014 year. There were 36 males and 11 females with age of 10 months to 65 years, mean age of 42.38±15.27 years. ResultsThere was no operative death within follow-up time of 18±7 months (ranged 14 to 1 586 days). Mitral valve function was normal or traces regurgitation in 33 patients (70.21%). Mild mitral regurgitation occurred in 11 patients (23.40%). Postoperative transesophageal echocardiography showed that 2 patients (4.26%) had moderate regurgitation. They underwent mitral valve repair again and cured. One patient (2.13%) underwent mitral valve replacement because of moderate to severe regurgitation. The dimensions of left atrium and left ventricle obviously decreased and heart function improved significantly compared with preoperative ones. ConclusionStrict control of surgical indications for different valve disease, the use of mitral valve repair technique, mitral surgery can get a good clinical efficacy. Preoperative diagnosis by transesophageal echocardiography, intraoperative monitoring, and immediate postoperative assessment for mitral valve repair results provide good technical support.
ObjectiveTo evaluate the effectiveness of preoperative immunosuppressive therapy combined with surgical intervention. MethodsA retrospective study was conducted on Behçet's disease patients who underwent cardiac surgery at Guangdong Provincial People's Hospital from 2012 to 2021. Patients were divided into immunosuppressive group and non-immunosuppressive group based on whether they received immunosuppressive therapy before surgery. The complications and long-term survival rates of the two groups were analyzed. ResultsA total of 28 patients were included, among which 2 patients underwent reoperation, a total of 30 surgeries were performed, including 16 males (53.3%), and the confirmed age was 37 (31, 45) years old. There were 15 surgeries in the immunosuppressive group and 15 surgeries in the non-immunosuppressive group. Compared with the non-immunosuppressive group, the incidence of complications during hospitalization in the immunosuppressive group was lower (13.3% vs. 53.3%, P=0.008). One patient died in hospital, and the rest were discharged and followed up, with a median follow-up time of 38.7 (15.1, 57.3) months, and there was no statistically significant difference in long-term survival rate between the two groups (26.7% vs. 6.7%, P=0.158). There was no statistically significant difference in the cumulative incidence of complications one month (20% vs. 53%, P=0.058) and one year (27% vs. 60%, P=0.065) after surgery between the immunosuppressive group and the non-immunosuppressive group, but there was a statistically significant difference in the cumulative incidence of complications three years after surgery (47% vs. 92%, P=0.002). ConclusionSurgical treatment can save lives in Behçet's disease patients with cardiovascular diseases, but the incidence of postoperative complications is high. Timely use of immunosuppressants before cardiovascular surgery can reduce the incidence of postoperative complications.
随着人口的老龄化，越来越多的有症状或无症状的冠心病患者需接受非心脏外科手术。接受非心脏外科手术而死亡的患者大约有50%是由于心脏并发症所致［1］。围手术期发生的心脏并发症大约5%～10%为心肌梗死，主要发生于术后头3天，其病死率很高，可达32%～69%［2，3］。术后发生心肌梗死或不稳定型心绞痛的患者发生心血管问题的几率增加20倍［4］。因此，如何评估非心脏外科手术患者的心脏危险性，如何预防围手术期心脏并发症的发生，已成为外科医生十分关注的一个问题。
Abstract： Objective To evaluate prediction validation of Sino System for Coronary Operative Risk Evaluation （SinoSCORE） on in-hospital mortality in adult heart surgery patients in West China Hospital.?Methods?We included clinical records of 2 088 consecutive adult patients undergoing heart surgery in West China Hospital from January 2010 to May 2012, who were also included in Chinese Adult Cardiac Surgical Registry.We compared the difference of preoperative risk factors for the patients between Chinese Adult Cardiac Surgical Registry and West China Hospital. SinoSCORE was used to predict in-hospital mortality of each patient and to evaluate the discrimination and calibration of SinoSCORE for the patients.?Results?Among the 2 088 patients in West China Hospital, there were 168 patients （8.05%） undergoing coronary artery bypass grafting （CABG）, 1 884 patients （90.23%） undergoing heart valve surgery, and 36 patients （1.72%） undergoing other surgical procedures. There was statistical difference in the risk factors including hyperlipemia, stroke, cardiovascular surgery history, and kidney disease between the two units.The observed in-hospital mortality was 2.25% （47/2 088）. The predicted in-hospital mortality calculated by SinoSCORE was 2.35% （49/2 088） with 95% confidence interval 2.18 to 2.47. SinoSCORE was able to predict in-hospital mortality of the patients with good discrimination （Hosmer Lemeshow test: χ2=3.164, P=0.582） and calibration （area under the receiver operating characteristic curve of 0.751 with 95% confidence interval 0.719 to 0.924）. Conclusion SinoSCORE is an accurate predictor in predicting in-hospital mortality in adult heart surgery patients who are mainly from southwest China
In recent years, transesophageal echocardiography has a trend toward miniaturization, so it has great clinical significance and broad clinical application prospect in the management of Cardiac Surgery ICU patient. This paper presents the characteristics of miniaturized transesophageal echocardiography and its clinical application. And we also focused on the contrast between miniaturized transesophageal echocardiography and standard transesophageal echocardiography and transthoracic echocardiography.
Objective To assess the value of pulmonary ventilation test in evaluating the prognosis of cardiac surgery patients. Methods Data were collected retrospectively from consecutive patients with coronary heart disease or valvular disease, who were prepared for cardiac surgery in Zhongshan Hospital from January 2007 to December 2008. The main outcome indices were mortality of surgery, the prolonging time of using artificial airway ( ≥3 days) , and the prolonging time in intensive care units ( ICU) ( ≥5 days) . Then the relationship between the poor outcome and ventilation disorder was analyzed. Results In the 422 cases,the incidence of ventilation disorder was 55% , included 27. 5% restrictive ventilation disorder, 15. 6% obstructive ventilation disorder, and 11. 8% mixed ventilation disorder. And the severity of pulmonaryventilation disorder was mild of 34. 6% , moderate of 15. 2% , and severe of 5. 2% . Among the 42 patients who gave up surgery,50% were due to ventilation dysfunction, and the patients were prone to give up surgery with the deterioration of pulmonary function( P lt; 0. 001) . But comparing with the patients with normal pulmonary function, the risk of poor outcome after surgery did not significantly increase in the patients with ventilation disorder ( P gt; 0. 05 ) . The logistic regression analysis indicated that cardiopulmonary bypass ( CPB) was an absolute risk factor ( P lt; 0. 05) . Conclusions The incidence of ventilation disorder in patients with cardiac disease is quite high. Severe pulmonary ventilation disorder is the significant cause of giving up surgery, but may be not the absolute contraindication of cardiac surgery.
ObjectiveTo analyze the effects of cardiovascular surgery on Williams syndrome (WS).MethodsThe clinical data of 68 WS patients undergoing cardiovascular surgery in the Department of Cardiac Surgery, Guangdong Provincial People's Hospital from January 2010 to January 2020 were retrospectively analyzed. There were 48 males and 20 females with a median age of 2.8 years ranging from 3 months to 33 years. Except one patient undergoing the coarctation repair, the rest 67 patients underwent surgical interventions to correct supravalvular aortic stenosis (SAVS) and pulmonary artery stenosis with hypothermic cardiopulmonary bypass, concommitant with 3 patients of relief of left ventricular outflow tract obstruction, 2 patients of relief of right ventricular outflow tract obstruction, 2 patients of mitral valvuloplasty, 3 patients of ventricular septal defect repair and 1 patient of arterial catheter ligation.ResultsTwo (2.9%) patients died of sudden cardiac arrest on the next day after surgery. One (1.5%) patient died of cardiac insufficiency due to severe aortic arch stenosis 3 years after surgery. The effect of SAVS was satisfactory. Two (2.9%) patients progressed to moderate aortic valvular regurgitation during postoperative follow-up. A total of 5 (7.4%) patients were re-intervened after operation for arch stenosis or pulmonary stenosis.ConclusionWS patients should be diagnosed early, followed up and assessed for cardiovascular system diseases, and timely surgical treatment has a good clinical effect.
