Impaction of Regurgitation Jet on Anterior Mitral Leaflet Causes Diastolic Dysfunction in Patients With Bicuspid Aortic Valve and Mild Insufficiency: A Cardiovascular Magnetic Resonance Study
Abstract:Purpose: To assess the impact of regurgitant jet direction on left ventricular function and intraventricular hemodynamics in asymptomatic patients with bicuspid aortic valve (BAV) and mild aortic valve regurgitation (AR), using cardiac magnetic resonance (CMR) feature tracking and 4D flow imaging.Methods: Fifty BAV individuals were retrospectively selected: 15 with mild AR and posterior regurgitation jet (Group-PJ), 15 with regurgitant jet in other directions (Group-nPJ) and 20 with no regurgitation (Controls)… Show more
