Annular Atrioventricular Valve Area Dynamics in Patients with Hypoplastic Left Heart Syndrome and Right Atrial Isomerism: Insights Using Speckle-Tracking of the Atrioventricular Valve Annulus
Abstract:Background: Atrioventricular valve regurgitation (AVVR) has a notable impact on the prognosis of patients with hypoplastic left heart syndrome (HLHS) and right atrial isomerism (RAI). Methods: The study population comprised two groups: (1) HLHS and RAI group: n 32 (HLHS 15, RAI 17), and (2) normal control group: n 53. X-plane images of apical four-chamber view and orthogonal plane cutting through the center of annulus were acquired using transthoracic matrix array probe. Speckle-tracking of the two opposing po… Show more
