Prominent V Waves Augment Right Ventricular Afterload Independent of the Lung Vessels in Heart Failure: Implications for Clinical Assessment of Pulmonary Vascular Disease

BACKGROUND: Left atrial (LA) stiffening augments the LA V wave, pressurizing the pulmonary artery (PA) out of proportion to left ventricular end-diastolic pressure. We characterized the pathophysiologic, diagnostic, and clinical implications of LA stiffening, as defined by promin...

Sotatercept Improves Right Heart Mechanics Despite Reduced Myocardial Contractility in Pulmonary Arterial Hypertension: A Prospective Exercise Hemodynamic Study

BACKGROUND: The right ventricular (RV) response to pressure overload is a crucial determinant of outcomes in pulmonary arterial (PA) hypertension. Sotatercept improves clinical outcomes, but its effects on the right ventricle have been inconsistent. We evaluated the effects of so...
