Analyse échocardio-graphique du ventricule droit

Abstract

Right ventricular (RV) function is essential in cardio-pulmonary physiology and physiopathology. RV dysfunction has prognostic impact in inferior myocardial infarction, significant valvulopathies, congenital cardiopathies, arterial pulmonary hypertension and in patients suffering from acute or chronic heart failure. RV analysis relies on non invasive (echocardiography-Doppler, isotopic technology, cardiac magnetic resonance imaging) and/or invasive approaches (right cardiac catheterization). Neglected a short time ago, RV assessment has regained interest with tissular Doppler imaging, strain imaging and 2D speckle tracking. We review echocardiography and Doppler parameters used for right ventricular assessment.
