Abstract
A patient with congenitally corrected transposition of the great arteries who presented with shortness of breath was found to have severe tricuspid regurgitation and right ventricular impairment. After uneventful mechanical systemic tricuspid atrioventricular valve replacement, the patient was extubated within 12 hours. On the first postoperative day, he developed episodes of profound hypotension lasting a few seconds. A transesophageal echocardiogram demonstrated displacement of the interventricular septum that caused systolic anterior motion of the mitral valve into the subpulmonic left ventricle. Mitral valve replacement resolved this complication, and the patient proceeded to do well at discharge.
