Severe Regurgitant Bicuspid Aortic Valve in a Patient with Overlapping Left Ventricular Noncompaction and Asymmetrical Septal Hypertrophy

Abstract

Abstract Overlapping of left ventricular noncompaction (LVNC) and hypertrophic cardiomyopathy in the same patient is rare and is associated with a more severe clinical course and unfavorable prognosis. The present report describes the case of a severely regurgitant bicuspid aortic valve in a 68-year-old man with overlapping LVNC and asymmetrical septal hypertrophy. Aortic valve replacement controlled the left ventricular dilatation that occurred secondary to the volume overload induced by the valvular disease. However, even 3 years postoperatively, severe systolic dysfunction persisted due to the preexisting myocardial disease, requiring close and lifelong follow-up with special attention to life-threatening arrhythmias and thromboembolism.
