Abstract

OBJECTIVE:

Congenitally corrected transposition of great arteries (CCTGA) is characterized by atrioventricular and ventriculoarterial discordance. Characterizations of these anomalies are important because they may influence surgical approach and management.

METHODS:

We present a case of newly diagnosed CCTGA at the age of 50. He presented with sudden onset of shortness of breath for the first time and was diagnosed with CCTGA. Echocardiogram, magnetic resonance imaging, and cardiac catheterization were utilized to elucidate the pathology.

RESULTS:

Intraoperatively, patient's CCTGA and ventricularization of the right ventricle were confirmed. The severe systemic atrioventricular valve regurgitation was replaced with a bioprosthetic valve (Medtronic Mosaic No. 29) with placement of epicardial ventricular leads for possible future placement of automatic implantable cardioverter defibrillators. Pathology report confirmed a degeneration of the systemic atrioventricular valve.

CONCLUSIONS:

Significant coronary artery anomalies have also been described in literature with CCTGA. The variances encountered in this case are excellent examples of the intricacies associated in diagnosis and surgical care in patients with CCTGA.
