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...
