Three-Dimensional Echocardiographic Assessment of Right Ventricular Global Myocardial Work and Ventricular–Pulmonary Coupling in ATTR Cardiac Amyloidosis
Background: Right ventricular (RV) function is inadequately investigated and routinely overlooked in transthyretin amyloid cardiomyopathy (ATTR-CM). Novel imaging distinguishers between intrinsic RV myocardial disease in ATTR-CM and primary RV overload disorder phenotypes may enhance mechanistic and pathophysiological understanding of RV dysfunction. We aimed to investigate RV performance in ATTR-
