Congenital coronary artery anomalies include various congenital anatomic anomalies of coronary artery. Severe congenital coronary artery anomalies usually result in ventricular dysfunction, myocardium ischemia, and even sudden death. Hence, understanding the coronary artery anomalies is critically important for the related surgeons to make reasonable strategies. This consensus is based on current literature and opinions of Chinese experts. And we mainly discuss the anatomy, clinical manifestation, diagnosis and treatment of important congenital coronary artery anomalies in clinics including anomalous aortic origin of a coronary artery, anomalous origin of the coronary artery from the pulmonary artery and coronary fistula.
Abstract: Objective To summarize the experience of surgical treatment of tetralogy of Fallot (TOF) with anomalous coronary artery. Methods From March 1993 to April 2006, 22 patients with TOF and anomalous coronary artery underwent repair. The resection of hypertrophied parietal, septal band and the ventricular septal defect (VSD) repairs were performed by trans-right ventricular outflow tract (RVOT) approach in 5 cases, and by transatrial approach in 17 cases, which consisted of 7 cases required a transannular patch to enlarge a pulmonary annulus, construction of a double barrel outlet in 6 cases, by autologous pericardium conduit (3 cases), homograft (1 case) and reflected anterior wall of the main pulmonary artery in combination with bovine pericardium (2 cases). Results There was one operative death because of the anomalous coronary artery impairment. The accessory left anterior descending artery was severed because it was mistaken for the conal arteryin 1 case, which caused failure to wean from bypass, after the left internal mammary artery was anastomosed to the accessory left anterior descending artery, the cardiopulmonary bypass (CPB) was stopped successfully. Mean early gradient(ΔP) was 23.4mmHg and ΔP＞20mmHg in 9 cases. Eighteen cases were followed up, mean time was 13.2 months. Late ΔP＞20mmHg in 7 cases, and ΔP were less than 20mmHg in 11 cases. Conclusion The repair of TOF with anomalous coronary artery is more safe by using the transatrial approach. The surgical reconstruction of RVOT depends on the anatomic characteristic of anomalous coronary artery.
Objective To sum up the therapeutic results of corrective surgery of 164 cases of tetralogy of Fallot (TOF), and explore the optimal time and risk factors of operation,as well as perioperative management. Methods One hundred and sixty-four consecutive cases of TOF underwent corrective surgery. There were simple stenosis of infundibular portion in right ventricular outflow tract in 37 cases, stenosis of infundibulum and pulmonary valve in 14 cases, main pulmonary trunk and left/right pulmonary arteries stenosis in 113 cases, and pulmonary atresia in 5 cases. Autologous pericardial conduit, valved homograft were used for right ventriculo-pulmonary artery connection, respectively. Other anomalies were corrected. Results The surgical mortality was 3.66% (6/164). The cause of death were serious low cardiac output syndrome(2 case), fail to wean from cardiopulmonary bypass after coronary artery bypass grafting (1 case), ventricular arrhythmia(1 case) and postoperative acute respiratory distress syndrome (2 cases). Conclusion It’s necessary to perform corrective operation on younger TOF patients. Low cardiac output syndrome is not the key reason of leading to postoperative complications or death. Preventing remnant obstruction of pulmonary artery and pulmonary complication should be focused during and after operation.
Objective To share the experience of the diagnosis and treatment of children with hand-foot-mouth disease. Methods We retrospectively analyzed 31 children with hand-foot-mouth disease in our hospital from April 2007 to June 2007 in terms of epidemiology, clinical features, treatment and prognosis. Results The average age of the children was 2.8 years, and 20 out of the 31 cases were from nurseries and kindergartens. Eighteen had clear contact history. Typical signs and symptoms, including oral ulcerative herpes and blister-like rash in extremities, were found in all cases. All the children were cured after timely diagnosis and early treatment with ribavirin, without any severe complications. Conclusion Timely treatment based on early diagnosis and considerate care are important for children with hand-foot-mouth disease. Nurseries, kindergartens and primary schools should attach great importance to relevant prophylaxis and isolation. These are essential for reducing the occurrence and prevalence of this disease.
Objective To investigate the safety and effectiveness of perventricular device closure (PDC) for congenital ventricular septal defects (VSD) by a meta-analysis.Methods PubMed, The Cochrane Library, EMbase and China Biology Medicine (CBM) databases were searched for studies on PDC of VSD up to October 2018 by computer. We included studies only with more than 80% patients diagnosed with perimembranous VSD. A meta-analysis was performed to obtain pooled estimates of success rate and incidences of complications with 95% confidence interval (CI). Subgroup analysis stratified by percentage of perimembranous VSD was performed. Risk difference (RD) was used in the comparison of perioperative data with follow-up data. Results Fifteen studies (2 randomized controlled trials, 3 retrospective cohorts, and other 10 retrospective single-arm studies) involving 4 164 patients (3 848 patients with perimembranous VSD) were included in this meta-analysis. The pooled success rate was 95.4%. Incidences of residual shunt, aortic insufficiency, tricuspid insufficiency, and third-degree atrioventricular block were 5%, 0.1%, 3%, and less than 0.001% respectively. Improvements of residual shunt and aortic insufficiency were confirmed in follow-up patients. Conclusion PDC of congenital perimembranous VSDs is safe and yields good results. Because some limitations can not be overcomed, multicenter randomized controlled trials are needed to confirm our results.
The surgical difficulty of congenital heart disease varies greatly. To ensure the safety of surgery and maximize the benefits of patients, various congenital heart surgery scoring systems have been used to evaluate the risk of different complex congenital cardiac operations. However, the complete correction of cardiac anatomical malformations is a common surgical challenge. Recent studies have shown that the correction is closely related to perioperative mortality and postoperative complications, and a new scoring system for the degree of cardiac anatomical malformations has been proposed. Therefore, this review summarizes the literature and discusses different evaluative methods of congenital heart surgery, aiming to optimize the surgical evaluation system for congenital heart surgery, enhance the quality of surgery and improve the prognosis of patients.
ObjectiveTo evaluate the economics of duplizumab in combination with optimal supportive care versus optimal supportive care for moderate-to-severe atopic dermatitis in adults from the perspective of our health system. MethodsA Markov model embedded in a decision tree was constructed to compare the long-term cost-utility of dupilumab combined with optimal supportive care versus optimal supportive care, and a sensitivity analysis was performed on the results. ResultsThe results of the basic analysis showed that compared with the optimal supportive care, dupliyuzumab in combination with optimal supportive care resulted in 3.82 more QALYs, while its cost was 125 549.42 yuan more. The ICER was 32 854.83 yuan/QALY, which was less than one times China's per capita GDP in 2022, and was economical. Univariate sensitivity analysis showed that factors such as Dupilumab-16-week post - no response utility value, Dupilumab-52-week post response rate and Dupilumab-52-week adherence had a greater impact on the cost changes. The results of the probabilistic sensitivity analysis showed a stable model structure and good robustness. ConclusionIn adult patients with moderate-to-severe atopic dermatitis, dupliyuzumab in combination with an optimal supportive care regimen is more cost-effective compared to an optimal supportive care regimen.
目的 观察和评价采用偏心型封堵器导管介入治疗干下型室间隔缺损的近期疗效和安全性。 方法 2011年8月－12月，6例经无主动脉瓣脱垂的干下型室间隔缺损（直径≤7 mm）患者（年龄＞3岁）在杂交手术室接受介入治疗。造影评估后，建立动静脉轨道，在保留导丝的情况下置入合适型号的国产偏心型室间隔缺损封堵器，并于术后定期随访复查。 结果 6例患者缺损直径4～7 mm（平均5.3 mm），其中5例成功地接受了导管介入封堵治疗，置入封堵器直径5～9 mm（平均6.4 mm）。仅1例因封堵器置入后出现主动脉瓣受压影响关闭，即改由外科微创经胸封堵成功。所有患者在随访期内，无栓塞、残余分流、瓣膜功能障碍、房室传导阻滞、死亡等并发症。 结论 无主动脉瓣脱垂的干下型室间隔缺损患者接受导管介入封堵治疗是安全、可行的，且短期随访结果良好。
ObjectiveTo evaluate the economics of nafamostat mesylate compared with unfractionated heparin for continuous renal replacement therapy anticoagulation. MethodsA decision tree model was constructed to calculate the cost difference between the two anticoagulation methods. Survival analysis data comes from retrospective literature in Asian countries. The cost data comes from procurement data and the prices of medical and health services in some regions. A 72-hour scenario analysis is performed and a sensitivity analysis is performed on key parameters. ResultsThe basic analysis results showed that compared with the unfractionated heparin group, the total cost difference of nafamostat in the 144-hour CRRT treatment was 5 350.34 yuan, and the unfractionated heparin was more economical. In the 72-hour scenario analysis, unfractionated heparin is also more economical. Univariate sensitivity analysis showed that the cost of single-use hemodialysis filters and supporting pipelines and the cost of plasma antithrombin Ⅲ activity (AT-Ⅲ) measurement had a greater impact on the change of the cost difference. The results of probability sensitivity analysis show that the model structure is stable and robust. When the unit price of nafamostat is about 110.82 yuan/piece, the cost of nafamostat and unfractionated heparin in 144-hour CRRT treatment is both 19 185.37 yuan, and the cost difference is 0.ConclusionWhen the unit price of nafamostat mesylate drops to a sufficiently low level, it could have an advantageous health economy.
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
