Role of 3D echocardiography‐determined atrial volumes in distinguishing between pre‐capillary and post‐capillary pulmonary hypertension

Abstract

The current guidelines on pulmonary hypertension (PH) recommend the use of invasive examination for differentiating between left‐sided heart disease‐related (post‐capillary) and pre‐capillary PH. However, atrial sizes are considered markers of ventricular filling pressures. Therefore, we aimed to test the clinical applicability of atrial volumes measured by transthoracic three‐dimensional echocardiography (3DE) in differentiating between pre‐capillary and post‐capillary PH.
