Incidence of Right Ventricular Dysfunction in an Echocardiographic Referral Cohort.

ABSTRACT:

Background

Incidence rates of right ventricular dysfunction (RVD) are unknown. We examined the rates, risk factors, and heart failure (HF) hospitalization hazard associated with incident RVD and right ventricle-pulmonary artery (RV-PA) uncoupling in patients referred for transthoracic echocardiogram (TTE).

Methods

In this retrospective cohort study, we extracted data from TTEs at Vanderbilt University Medical Cente (2010-2023). We followed patients from their earliest TTE with normal right ventricle function (tricuspid annular plane systolic excursion [TAPSE] ≥17 mm). The primary outcomes were new RVD (TAPSE <17 mm) and RV-PA uncoupling (TAPSE/right ventricular systolic pressure <0.36 mm/mm Hg). We evaluated risk factors for and hazard of HF hospitalization associated with e
