Quadricuspid Aortic Valve: Report of Two Cases and Brief Review [PDF]

Case Reports in Cardiology, 2019
Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect characterized by the presence of four aortic valve leaflets of equal or varying sizes. Even rarer is its clinical presentation with aortic stenosis. Diagnosis of QAV could be challenging

Quadricuspid Aortic Valve With Severe Aortic Regurgitation. [PDF]

Clin Case Rep
ABSTRACT Whenever a quadricuspid aortic valve (QAV) was present, it was historically only identified during open heart surgery. However, recent advances in transthoracic echocardiography have made it possible to detect QAV preoperatively. Further evaluation using transesophageal echocardiography or computed tomography before open surgery may help guide

Transcatheter Aortic Valve Replacement in Patients With Quadricuspid Aortic Valve: A Case Series and Systematic Review. [PDF]

Cardiol Res Pract
Background: Quadricuspid aortic valve (QAV) is a rare congenital cardiac anomaly associated with symptomatic aortic regurgitation (AR) or aortic stenosis (AS). Transcatheter aortic valve replacement (TAVR) for QAV remains uncertain. Methods: We retrospectively reviewed prospectively collected data from patients with QAV undergoing TAVR in our center ...

Transthoracic echocardiography and its limitations in the diagnosis of congenital supernumerary aortic valve in a Thoroughbred

Veterinary Medicine and Science, 2023
Aortic valve malformation is a common congenital abnormality reported in human medicine. The malformation is characterised by an increased or decreased number of cusps. Anatomical variations of the aortic valve that have been documented in humans include

Quadricuspid Aortic Valve With Guarded Left Coronary Artery Ostium in an Infant With Myocardial Infarction [PDF]

, 2022
Anatomical variations of the aortic valve include unicuspid, bicuspid, and quadricuspid. The bicuspid aortic valve is most common and affects 1%-2% of the general population. QAV is generally an isolated malformation, and adults most commonly present
