Double outlet left ventricle: how should we repair it?
The Journal of Cardiovascular Surgery
|July 1, 1979
Summary
Two patients with double outlet left ventricle (D.O.L.V.), ventricular septal defect (V.S.D.), and pulmonary stenosis (P.S.) underwent successful surgical repair. The "extraventricular" approach offers a promising surgical option for this rare congenital heart defect.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Medical Case Reports
Background:
- Double outlet left ventricle (D.O.L.V.) is a rare congenital heart malformation.
- Surgical correction is complex and requires precise anatomical understanding.
- Previous reports detail various surgical strategies for D.O.L.V. repair.
Observation:
- Two patients with D.O.L.V., V.S.D., and P.S. were surgically treated.
- The seventh and eighth successful D.O.L.V. repairs are presented.
- Preoperative diagnosis relied on detailed left ventriculography.
Findings:
- Successful surgical correction was achieved using an "extraventricular" repair technique.
- This involved V.S.D. closure, interruption of left ventricle-pulmonary artery continuity, and a right ventricle-pulmonary artery conduit.
- A fresh aortic homograft was utilized as the conduit.
Implications:
- The "extraventricular" repair is presented as a potentially safer alternative to "intraventricular" repair for D.O.L.V.
- This technique appears to have fewer contraindications and complications.
- Successful surgical outcomes highlight the feasibility of advanced cardiac repair in complex congenital cases.
