Ischemic Stroke in a Patient With Quadricuspid Aortic Valve and Patent Foramen Ovale

Abstract

Quadricuspid aortic valve (QAV) is a rare congenital aortic valve abnormality. It is less common as compared to bicuspid or unicuspid aortic valve abnormality. QAV causes aortic regurgitation usually in the fifth to sixth decade of life. We present a rare case of a female patient with cryptogenic stroke due to a QAV and a patent foramen ovale (PFO). The patient underwent transcatheter closure of PFO, as there was no clear indication for surgery for her valve. Surgical removal remains the method of choice for the treatment of the QAV before left ventricular decompensation occurs.

Quadricuspid Aortic Valve: Report of Two Cases and Brief Review

“…Quadricuspid aortic valve (QAV) usually presents as an isolated congenital anomaly, but other associated cardiac anomalies have been reported in about 18-32% of cases including aortic root dilatation [13], tetralogy of Fallot [14], patent ductus arteriosus [15], atrial and ventricular septal defects [16, 17], and anomalous origin of the coronary arteries [12].…”
