Right Ventricular Geometry and Function in Pulmonary Hypertension: Non-Invasive Evaluation
AbstractPulmonary hypertension (PH) is a rare disease, which still carries a poor prognosis. PH is characterized by a pressure overload on the right ventricle (RV), which develops hypertrophy, followed by a progressive failure. Accordingly, recent evidence showed that RV function has an important prognostic role in patients with PH. Echocardiography, cardiac magnetic resonance (CMR), computed tomography, and nuclear imaging allow a non-invasive evaluation of the RV size and function, but only the first two are routinely used in the clinical arena. Some conventional echocardiographic parameters, such as TAPSE (tricuspid anular plane systolic excursion), have demonstrated prognostic value in patients with PH. Moreover, there are some new advanced echo techniques, which can provide a more detailed assessment of RV function. Three-dimensional (3D) echocardiography allows measurement of RV volumes and ejection fraction, and two-dimensional (2D) speckle tracking (STE), allows assessment of RV myocardial mechanics. CMR provides accurate measurement of RV volumes, ejection fraction, and mass and allows the characterization of the RV wall composition by identifying the presence of fibrosis by late gadolinium enhancement. Although CMR seems to hold promise for both initial assessment and follow-up of patients with PH, its main role has been restricted to diagnostic work-up only. View Full-Text
