Defining Echocardiographic Degrees of Right Heart Size and Function in Pulmonary Vascular Disease From the PVDOMICS Study

Defining qualitative grades of echocardiographic metrics of right heart chamber size and function is critical for screening, clinical assessment, and measurement of therapeutic response in individuals with pulmonary vascular disease (PVD). In a population enriched for PVD, we sought to establish qualitative grades and prognostic value of right heart chamber size and function.
