Right Ventricular Dysfunction Compromises Accuracy of Echocardiographic Diagnosis of Pulmonary Hypertension in Heart Failure

Abstract Background The Swan-Ganz catheter and echocardiography (ECHO) are commonly used to measure pulmonary artery systolic pressure. It is unknown how right ventricular dysfunction influences the accuracy of ECHO-derived estimation of pulmonary hypertension in patients with severe left ventricula...

Description
Summary:Abstract Background The Swan-Ganz catheter and echocardiography (ECHO) are commonly used to measure pulmonary artery systolic pressure. It is unknown how right ventricular dysfunction influences the accuracy of ECHO-derived estimation of pulmonary hypertension in patients with severe left ventricular systolic dysfunction. Methods and Results We analyzed a limited-access dataset from the ESCAPE (Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness) trial provided by the National Heart, Lung, and Blood Institute. Patients enrolled in this trial had left ventricular ejection fraction
