Aortico-left ventricular tunnel: 35-year experience.
Journal of the American College of Cardiology
|July 21, 2004
Summary
Aortico-left ventricular tunnel (ALVT) is a rare congenital heart defect. Surgical intervention offers good long-term outcomes, though conservative follow-up may be considered for select cases.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Aortico-left ventricular tunnel (ALVT) is a rare congenital cardiac anomaly.
- Neonatal surgical intervention is often recommended due to concerns about long-term aortic regurgitation (AR).
Purpose of the Study:
- To review 35 years of experience with ALVT.
- Emphasis on diagnostic methods, surgical techniques, and patient follow-up.
Main Methods:
- Retrospective review of 11 patients diagnosed with ALVT between 1963 and 2002.
- Analysis of clinical data, echocardiography, cardiac catheterization, and surgical records.
Main Results:
- Eight patients presented in infancy with congestive heart failure; three later with murmurs and AR.
- Associated cardiac anomalies, including aortic valve and coronary artery issues, were present in 45% of patients.
- Ten patients underwent surgical repair, with most achieving asymptomatic status post-operatively, experiencing only mild or trivial residual AR.
Conclusions:
- ALVT is a rare malformation with favorable long-term outcomes following surgical repair.
- Associated lesions are common; surgical management is recommended for most patients.
- Conservative management may be considered for rare, small, asymptomatic ALVT cases, with catheterization reserved for diagnostic uncertainty or transcatheter closure.
