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.
ObjectiveTo explore the relationship between platelet and prognosis of the total correction of tetralogy of Fallot (TOF). MethodsWe included 11 dead patients with TOF at age of 0-6 years as a death group between 2011 and 2014 year. There were 7 male and 4 female patients at age of 18.6±16.4 months in the death group. We selected 11 matched survival patients according to age, gender of the patients as a survival group. There were also 7 male and 4 female patients at age of 19.4±16.7 months in the death group. The patients were divided into a high-platelet group and a low-platelet group. There were 6 male and 5 female patients in the high-platelet group. While there were 8 male and 3 female patients in the low-platelet group. Inflammatory cytokine and mortality were compared between the two groups. ResultsPost-operative count of platelet in the death group was significantly lower than that in the live group, while post-operative interleukin-6 (IL-6) and C reactive protein (CRP) were much higher than those in the death group (P<0.05). Mortality was higher in the low-platelet group than that in the high-platelet group (P<0.05). ConclusionPlatelets may alleviate inflammatory response and reduce mortality, which played a great role of protection.
目的評價單穿刺點經胸微創封堵治療房間隔缺損（ASD）合并室間隔缺損（VSD）的安全性及有效性。 方法納入2014年6月至2015年8月于我院成功完成單穿刺點經胸微創封堵術治療ASD合并VSD的8例患兒，分析患兒在術后第l個月、3個月、6個月的門診隨訪資料。觀察圍術期及隨訪期間患者殘余分流、瓣膜反流、心律失常等并發癥發生情況。 結果8例患兒中，術后早期均無殘余分流、心律失常，微量三尖瓣反流（TR）患者1例（12.5%）。平均隨訪時間5～9（6±2）個月，各瓣膜均未發現中度及以上反流，未發現存在血栓、嚴重心律失常、死亡的患者。 結論單穿刺點經胸微創封堵治療ASD合并VSD安全、有效，且更為微創。
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.
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.
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 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.
