Echocardiographic features before and after the Jatene procedure (anatomical correction) for transposition of the great vessels.

Eight patients with complete transposition of the great vessels (TGA) underwent the Jatene procedure and repair of major associated anomalies. All were studied preoperatively by M-mode and two-dimensional echocardiography (2DE) and by cardiac catheterization. Six patients survived operation and were studied postoperatively by both echocardiographic methods; five also underwent cardiac catheterization and angiography. In these patients, 2DE accurately predicted the anatomic features preoperatively and provided an important adjunct to catheterization and angiocardiography.
