The main imaging modality of the (failing) right ventricle is echocardiography. A detailed assessment of the anatomy and function of the right side should include left heart function, pulmonary hemodynamics, the tricuspid valve and the right atrium. Transthoracic assessment by echocardiography is sufficient to describe the right ventricular morphology and function adequately. Cardiac MRI It become the standard reference method for right heart acquisition as it is capable of visualizing anatomy, quantifying function and calculating flow. In addition, it is useful in cases where image quality by echocardiography is limited. In spite these benefits there are some limitations to the cardiac MRI mainly due to the thinning of the right ventricular wall, which can make it challenging to differentiate it from surrounding tissues. In addition, pacemakers or pacemaker leads may interfere with image acquisition during MRI and lead to artefacts that impair visualization of the right ventricular walls.
