[A successful surgical repair of bilateral atrioventricular valve regurgitation in corrected transposition of the great arteries]

Abstract

The patient was a 52-year-old female with bilateral atrioventricular valve regurgitation, who had SLL-type corrected transposition of the great arteries (C-TGA) accompanied by atrial fibrillation and ventricular extrasystoles (Lown 4b). In performing C-TGA in a patient at such an age, the ability of the anatomical right ventricle to maintain the systemic circulation is reduced, and so it is most important to maintain ventricular function at operation. In this case, we preserved the tricuspid valve and transplanted a biological valve at the tricuspid annulus, while the mitral valve was repaired with Kay's method of annuloplasty. Her postoperative progress was favorable and the echocardiography confirmed that the preserved tricuspid valve did not disturb the motion of the leaflets of the biological prosthesis.
