Insights
This study reports on surgical outcomes for five pediatric patients with ventricular septal defect (VSD) and aortic incompetence (AI). Modified Trusler
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Context:
- Ventricular septal defect (VSD) and aortic incompetence (AI) are complex congenital heart conditions.
- Surgical management in pediatric patients presents unique challenges.
- This study focuses on a specific cohort of young patients with coexisting VSD and AI.
Purpose:
- To report surgical outcomes in pediatric patients with VSD and AI.
- To evaluate the efficacy of modified Trusler's aortic valvuloplasty and aortic valve replacement.
- To discuss surgical techniques, anatomical considerations, and indications for intervention.
Summary:
- Five pediatric patients (ages 4-14) with VSD and AI underwent surgical repair.
- Three patients received modified Trusler's aortic valvuloplasty; two with endocarditis had aortic valve replacement.
- VSD closure was achieved via Dacron patch or direct repair.
- Valvuloplasty showed good immediate and medium-term results, with murmur regression.
Impact:
- Modified Trusler's valvuloplasty is recommended for severe AI in pediatric VSD cases.
- The study contributes to understanding surgical strategies for complex congenital heart defects.
- Findings may inform clinical decision-making for similar patient populations.
Abstract:
The results of surgery on five patients aged between 4 and 14 years old with ventricular septal defect (VSD) and aortic incompetence (AI) are reported. Four of the five patients had massive AI, the diastolic blood pressure being 0 in 3 cases. All patients underwent catheterisation and angiography. In 1 case, an aneurysm of the sinus of Valsalva bulging into the infundibulum was detected. At operation, 3 infra-cristal, 1 supra cristal and 1 unclassified VSD were observed. Prolapse of the aortic cusps was present in three cases, and in two cases these lesions were complicated by infective endocarditis. Three patients were managed by a slightly modified version of Trusler's aortic valvuloplasty, and the two patients with endocarditis underwent aortic valve replacement. The VSD was closed by Dacron patch in 3 cases and directly in 2 cases. The immediate postoperative period was complicated in one case by haemorrage due to anticoagulant therapy causing tamponade and paraplegia. In the other four cases, there were no complications. The results of valvuloplasty were good with complete regression of the diastolic murmur. The medium-term results were good, with a maximum follow-up period of 21 months. One of the patients with an aortic valve prosthesis has minimal AI, probably due to a paravalvular leak. A number of points are discussed with respect to this small series of patients: anatomy, techniques, indications. The modified Trusler's valvuloplasty is recommended, even in cases of severe AI.
