Quadricuspid aortic valve: a rare but important abnormality.

The article presents a case study of an asymptomatic patient, found with a 2/6 grade holosystolic apical cardiac murmur on routine physical examination, and mentions that patient's transthoracic echocardiography (TTE) demonstrated quadricuspid aortic valve (QAV), mild aortic regurgitation (AR) and a small restrictive muscular ventricular septal defect (VSD). It also suggests that patient's follow-up was recommended to monitor QAV for the early detection of any functional deterioration.
