Quadricuspid aortic valve: Case series and review of literature

Quadricuspid Aortic Valve: Imaging, Diagnosis, and Prognosis

Quadricuspid aortic valve is a rare congenital cardiac anomaly with an incidence of 0.008% to 0.043%. Its clinical course varies depending on cusp anatomy, function, and associated cardiac malformations. It frequently progresses to aortic valve regurgitation that may require surgical valve replacement. Detection has shifted from incidental discovery during autopsies or cardiac surgeries in the early 20th century to various cardiac imaging methods in recent decades. In addition to contributing to the literature, this report supports the use of transesophageal echocardiography more liberally to detect aortic valve abnormalities. The case presents a 48-year-old female patient with an incidentally discovered quadricuspid aortic valve.

Quadricuspid aortic valve and a large patent ductus arteriosus treated with device closure

Quadricuspid aortic valve is a remarkably rare congenital cardiac anomaly that predominantly becomes regurgitant with the passage of time. Aortic valve stenosis and aortic root dilatation are less common in quadricuspid aortic valve as compared to bicuspid aortic valve. The clinical presentation depends upon the functional status of the aortic valve, left ventricular function, and associated cardiac or coronary anomalies. The quadricuspid aortic valve is easily visualised during transthoracic echocardiogram with a characteristic X pattern of aortic valve in diastole. The association of quadricuspid aortic valve with patent ductus arteriosus is exceedingly rare. We are reporting a case of young girl with mildly regurgitant quadricuspid aortic valve, large patent ductus arteriosus, and volume-loaded left heart who underwent a successful device closure of her patent ductus arteriosus. To the best of our knowledge, such a case is being reported from Pakistan for the first time.

A dissecting aneurysm of the sinus of Valsalva involving the inter-ventricsular septum in a patient with syphilis and a quadricuspid aortic valve

Aneurysms of the sinus of Valsalva are rare, with dissecting aneurysms of the sinus of Valsalva that extend into the inter-ventricular septum being even more rare. This report describes a young patient with syphilis and a quadricuspid aortic valve who experienced a spontaneously dissecting aneurysm of the sinus of Valsalva and the basal inter-ventricular septum.

Quadricuspid aortic valve: a case report and review of literature

Quadricuspid aortic valve, a rare congenital cardiac defect, manifests most commonly as aortic regurgitation. Clinical presentation mainly depends on the functional status of the aortic valve, myocardium and associated cardiovascular abnormalities. Aortic valve replacement or repair is usually warranted in the 5th or 6th decade.
