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.
ObjectiveTo summarize perioperative management experience of 16 patients undergoing surgical correction of anomalous origin of the left coronary artery from pulmonary artery (ALCAPA). MethodsWe performed a retrospective analysis of 16 patients who received surgical correction of ALCAPA between January 2005 and December 2013 in Cardiovascular Center of Children's Hospital of Fudan University. There were 6 males and 10 females with their age ranging from 2 months to 13 years (mean age of 23.25±0.63 months) and body weight ranging from 5 to 30 kg (mean body weight of 19.77±0.75 kg). All the patients underwent direct implantation of the anomalous coronary artery into the ascending aorta, and received comprehensive management regarding left ventricular ejection fraction (LVEF), heart rate, blood pressure, arterial blood gas, urinary volume, blood lactic acid and central venous pressure. ResultsPostoperative complications were low cardiac output syndrome (LCOS) in 9 patients (including intractable LCOS in 2 patients) and arrhythmia in 1 patient. One patient with intractable LCOS and arrhythmia died postoperatively with the mortality of 6.25%. Cardiopulmonary bypass time was 85-260 (135.61±35.01) minutes, aortic cross-clamping time was 40-97 (57.32±16.02) minutes, mechanical ventilation time was 34-187 (106.34±41.62) hours, length of CICU stay was 2-21 (8.13±5.02) days, and hospital stay was 12-51 (22.14±5.00) days. Postoperative LVEF and left ventricular fractional shortening were significantly higher than preoperative values (P < 0.05). ConclusionKey points for successful surgical correction of ALCAPA include meticulous perioperative management, preoperative heart function improvement, prevention of postoperative complications and use of new techniques.
