Current Knowledge and Recent Advances of Right Ventricular Molecular Biology and Metabolism from Congenital Heart Disease to Chronic Pulmonary Hypertension

Figure 2

18-Fluorodeoxyglucose Positron Emission Tomography in a control healthy patient (a), in a patient with aortic valve sclerosis (b), and in a chronic thromboembolic pulmonary hypertension patient (CTEPH) (c). Images show 4 chambers views. Control imaging shows no right ventricular uptake, but presence of left ventricular uptake. Picture (b) shows increased glucose uptake localized on the left ventricular free wall and on the interventricular septum in a patient with marked hypertrophy of the left ventricle due to aortic sclerosis.
