  • Surgical Treatment of Tetralogy of Fallot with Anomalous Coronary Artery

    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.

  • Surgical Treatment of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery

    ObjectiveTo explore surgical methods and risk factors of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). MethodsClinical data of 28 ALCAPA patients who underwent surgical repair from October 1993 to September 2013 in Beijing Anzhen Hospital were retrospectively reviewed. There were 8 male and 20 female patients with their age of 0.6-l6.8 (4.3±0.7)years including 10 patients less than 1 years old. Surgical procedures included simple ligation of left coronary artery, intrapulmonary tunnel procedure (Takeuchi)and direct coronary reimplantation of the anomalous artery. Postoperative death, complication and cardiac function were observed. ResultsAmong the 28 patients, 1 patient received simple ligation of left coronary artery, and 7 patients received intrapulmonary tunnel procedure (Takeuchi), among whom 2 patients died postoperatively. Twenty patients received direct implantation of the anomalous artery into the ascending aorta, and 3 patients died postoperatively. Five patients who died postoperatively were 10.20±3.27 months old, including 3 patients with moderate mitral regurgitation (MR)and 2 patients with mild MR preoperatively. Preoperative heart function of the patients who died postoperatively was significantly reduced. Preoperative left ventricular ejection fraction of the patients who died postoperatively was significantly lower than that of the patients who survived (36.6%±8.5% vs. 60.9%±10.7%, P=0.000). Low cardiac output syndrome was the reason for all postoperative death. All survival patients were followed up from 1 month to 18 years. One patient who underwent intra-pulmonary tunnel procedure (Takeuchi)received pulmonary artery balloon dilatation for pulmonary supravalvular stenosis 15 years after discharge. None of the other patients received a secondary operation. During follow-up, left ventricular function was improved. Growth and development of all the patients was normal. MR did not significantly aggravate in all the patients. ConclusionPatients with younger age and worse left ventricular function have greater surgical risks of ALCAPA.

  • The application value of virtual reality technology in the surgical treatment of coronary artery fistula and abnormal origin of coronary artery

    ObjectiveTo evaluate the application value of virtual reality (VR) technology in the surgical treatment of coronary artery fistula (CAF) and abnormal origin of coronary artery (AOOCA).MethodsFrom January 2014 to June 2018, with the assistance of virtual reality technology, 4 patients with CAF and 4 patients with AOOCA in the Department of Cardiac Surgery of our hospital underwent treatment method deciding and operation details planning. In the CAF patients, there was 1 male and 3 females and they were 8 years, 16 years, 62 years, and 65 years, respectively. In the AOOCA patients, there was 1 male and 3 females at age of 4-month, 2 years, 14 years, and 29 years, respectively.ResultsThe virtual heart models in all 8 patients were well matched with the real heart. The spatial structure information of CAF/AOOCA and surroundings can be intuitively and fully shown by virtual reality technology in all patients. All of the 4 CAF patients repaired coronary artery incision, including 2 patients with autologous pericardium patch and 2 patients with direct suture. Of the 4 AOOCA patients, 3 underwent coronary directly transplantation but 1 underwent Takeuchi surgery. And 2 had mitral valve plasty at the same time. All the operations were completed successfully, with good recovery and no serious complications. Among the 4 CAF patients, 3 had no residual fistula, and 1 had minor residual fistula. Coronary arteries were all unobstructed in 4 patients of AOOCA; moderate and severe mitral regurgitation in 2 patients were significantly reduced after surgery.ConclusionVR allows doctors to understand the spatial structure information of CAF/AOOCA and surroundings before the operation, and assists them to make accurate treatment decisions and develop detailed surgical plans before the operation, ensuring its safety. Its clinical application value is significant.

  • Chinese expert consensus on surgical treatment of congenital heart disease (12): Congenital coronary artery anomalies

    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.

  • Individualized surgical treatment strategy for children with anomalous aortic origin of coronary artery

    ObjectiveTo summarize and explore the individualized surgical treatment strategy and prognosis of anomalous aortic origin of coronary artery (AAOCA). MethodsThe clinical data of children with AAOCA admitted to Shanghai Children's Medical Center from March 2018 to August 2021 were retrospectively analyzed. ResultsA total of 17 children were enrolled, including 13 males and 4 females, with a median age of 88 (44, 138) months and a median weight of 25 (18, 29) kg. All patients received operations. The methods of coronary artery management included coronary artery decapitation in 9 patients, coronary artery transplantation in 5 patients and coronary artery perforation in 3 patients. One patient with severe cardiac insufficiency (left ventricular ejection fraction 15%) received mechanical circulatory assistance after the operation for 12 days. No death occurred in the early postoperative period, the average ICU stay time was 4.3±3.0 d, and the total hospital stay was 14.4±6.1 d. All the children received regular anticoagulation therapy for 3 months after discharge. The median follow-up time was 15 (13, 24) months. All patients received regular anticoagulation therapy for 3 months after discharge. No clinical symptoms such as chest pain and syncope occurred again. The cardiac function grade was significantly improved compared with that before operation. Imaging examination showed that the coronary artery blood flow on the operation side was unobstructed, and no restenosis occurred. ConclusionAAOCA is easy to induce myocardial ischemia and even sudden cardiac death. Once diagnosed, operation should be carried out as soon as possible. According to the anatomic characteristics of coronary artery, the early effect of individualized surgery is satisfactory, and the symptoms of the children are significantly improved and the cardiac function recovers well in the mid-term follow-up.
