Right ventricular wall can be thickened 4 mm often observed in congenital heart disease or dilated in acquired heart disease free wall may be hypokinetic. A right ventricle left ventricle rv lv ratio 1 0 was not associated with fewer favorable outcomes in patients with symptomatic acute pulmonary embolism pe who were otherwise considered low risk according to study results published in the american journal of respiratory and critical care medicine.

The objective of this study is to identify a clinical scenario for which normal ct derived right to left ventricular rv lv ratio. In the study by araoz et al 42 an rv lv diameter ratio greater than 1 was associated with a 3. The right ventricular to left ventricular diameter rv lv ratio measured at ct pulmonary angiogram ctpa has been shown to provide valuable information in patients with pulmonary arterial hypertension and to predict death or deterioration in acute pulmonary embolism.
