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

Cardiology Research and Practice, Volume 2025, Issue 1, 2025.
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 ...

Uncommon presentations of type A quadricuspid aortic valve in the Septuagenarian [PDF]

Journal of Cardiothoracic Surgery
Background Quadricuspid aortic valve (QAV) is a rare congenital anomaly characterized by the presence of four cusps instead of the usual three. It is estimated to occur in less than 0.05% of the population, with Type A (four equal-sized leaflets ...

Tricuspidization: repair of a quadricuspid aortic valve [PDF]

Journal of Cardiothoracic Surgery
Quadricuspid aortic valve (QAV) is rare. However, to repair a quadricuspid aortic valve is not as easy to realize as in bicuspid aortic valve. The surgical design is crucial to rebuild the stable structure.

Quadricuspid aortic valve repair with a modified‐tricuspidization technique [PDF]

Echocardiography, Volume 39, Issue 10, Page 1363-1366, October 2022., 2022
Abstract Introduction Quadricuspid aortic valve (QAV) is an extremely rare developmental abnormality with an incidence of 0.006%. QAV is an incidental finding that in some patients (23%) may determine aortic regurgitation (AR). Altogether 16% of patients indeed require surgery with AR being the most frequent indication.

Two Cases of Quadricuspid Aortic Valve: Aortic Regurgitation and Degeneration

The Thoracic & Cardiovascular Surgeon Reports, 2022
Background Quadricuspid aortic valve is rare and occasionally associated with aortic regurgitation and ascending aortic dilatation. Recent studies suggest an association of aortic regurgitation with ascending aortic medial degeneration.

Repair of quadricuspid aortic valve by bicuspidization: a novel technique [PDF]

, 2010
Quadricuspid aortic valve (QAV) is a rare congenital lesion, generally manifesting with valve regurgitation. Standard treatment involves valve replacement, though anecdotal cases of successful repair by means of valve tricuspidization have
