Objective To investigate the effect of surgical treatment on ventricular septal defect (VSD) in infants under 6kg weight, including the operative indication, surgical techniques and perioperative therapy. Methods All clinical data of 148 consecutive infants under 6kg weight with VSD were collected and studied retrospectively. The infants, age was 1-13(mean 5.3) months with the body weight of 3.5-6.0 (mean 5.3) kg. VSD was perimembranous in 105 cases, subpulmonary in 25, muscular inlet tract in 8, muscular outlet tract 9, and muscular trabecular in 1 case. Other associated cardiac abnormalities included atrial septal defect in 39, patent ducts arteriosus in 17, insufficiency of mitral valve in 9 and moderate to severe pulmonary hypertension in 52. The operations were performed under cardiopulmonary bypass at moderate to low flow, moderate hypothermia and cold crystalloid cardioplegia. Patch repair was used in 85, direct sutures in 63 and 23 cases repaired with partial sternal incision and beating heart. Results The hospital mortality was 4. 1% (6/148), the causes of death were severe pulmonary hypertention in 2, aortic arch interruption in 2, severe malnutrition in 1 and poor result of mitral valvuloplasty in 1. Other major operative complications included residual shunts (1- 2mm) in 2, and Ⅲ° A-V block in 2, who recoveried 5 days after the operation. The hospital stay was 6 15 (mean 8) days. Follow-up was complete in all 142 survived cases for 4 months-6 years. Two residual shunts healed in first year after the cardiac operation, others recovery smoothly, and are developing well. Conclusion With the improvement of the surgical techniques, the surgical treatment for VSD in infants with low weight is safe and effective, and it is also essential to further improve the effects of surgical treatment in VSD associated with complex abnormalities.
ObjectiveTo summarize the application and clinical effect of left anterior minimally invasive thoracotomy to surgical repair of subarterial ventricular septal defect (VSD) in children.MethodsFrom October 2015 to April 2019, 21 children with subarterial VSD underwent surgical repair via left anterior minimally invasive thoracotomy. There were 13 males and 8 females, aged 5-13 (9.1±2.2) years, and weighing 22-55 (35.6±9.5) kg. The diameter of subarterial VSD was 4-15 (9.1±3.3) mm. Eight patients had right coronary valve prolapse, and 4 aortic valve regurgitation (3 mild and 1 mild-to-moderate). The minimally invasive surgery was performed via left parasternal thoracotomy through the second or third intercostal space. The peripheral perfusion was performed with femoral arterial and venous cannulation. After aortic cross-clamp (ACC), subarterial VSD was performed with direct suture of patch closure through an incision on the root of pulmonary artery.ResultsAll patients successfully underwent surgical repair (patch closure, n=15; direct suture, n=6) of subarterial VSD through left anterior minimally invasive thoracotomy. The cardiopulmonary bypass time was 45-68 (57.1±6.3) min. The ACC time was 23-40 (32.6±4.7) min. The postoperative ventilation time was 5-9 (6.3±1.3) h, postoperative in-hospital time was 5-8 (5.7±1.0) d and drainage volume was 33-105 (57.5±17.7) mL in postoperative 24 h. No death, residual VSD shunt, atrioventricular block, wound infection or thoracic deformity occurred during the perioperation or follow-up. Only one patient still had trivial aortic valve regurgitation.ConclusionLeft anterior minimally invasive thoracotomy could be safely and effectively applied to surgical repair of subarterial VSD in children, with satisfactory early- and mid-term outcomes.
ObjectiveTo investigate the effectiveness and safety of esophageal ultrasound-guided percutaneous femoral artery closure of ventricular septal defect (VSD).MethodsThe clinical data of 24 patients with congenital VSD in our hospital from March 2017 to December 2019 were retrospectively analyzed, including 6 males and 18 females, with a median age of 12 (3-42) years, weight of 32 (12-91) kg, and VSD diameter of 4 (3-7) mm. There were 3 patients with VSD combined with atrial septal defect.ResultsTwenty-four patients successfully underwent interventional closure of percutaneous femoral artery under esophageal ultrasound guidance, and the position and shape of the occluders were good. The operation time was 45 (39-54) min, and the waist size of the occluders was 7 (5-12) mm. Among the patients, 14 patients used symmetric ventricular occlusion devices, 8 patients used asymmetric ventricular occlusion devices, and 2 patients used ventricular occlusion muscle occluders. Small amount of residual shunt occurred in 2 patients after the operation and it disappeared 3 months after the operation. One patient with right bundle branch block, which disappeared after 1 week of observation. There were no complications such as occluder closure, pericardial effusion or valve regurgitation during the perioperative period. During the follow-up period [3-18 (9.25±5.04) months], no serious complication occurred.ConclusionTransesophageal ultrasound-guided transfemoral artery occlusion for VSD is simple and safe, and it avoids the damage of radiation and contrast medium. It has advantages over traditional percutaneous interventional occlusion therapy.
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.
