Imaging the right ventricle in pulmonary hypertension

Abstract

DOI: 10.4103/0974-6013.54760 but heavily trabeculated. It is a low-pressure volume pump, working against a resting pulmonary vascular resistance (PVR), which is only one-fifteenth of normal systemic vascular resistance. The thin-wall, anterior, midline orientation, and complex geometry of the RV pose particular challenges for all imaging methods. The techniques that have been used with considerable success in PH patients are echocardiography (including 3-dimensional echocardiography and Tissue Doppler Imaging), cardiac magnetic resonance (CMR) imaging and cardiac computed tomography (CT) imaging.
