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.
The assessment of rv function starts with the measurement of rv dimentions and the qualitative evaluation of its function.

To identify a clinical scenario for which ct rv lv ratio was considered sufficient to exclude rv strain or pe related short term death a multivariable logistic model was created to detect factors related to subjects for whom subsequent echocardiography detected rv strain or those who did not receive echocardiography and died of pe within 14.
The right ventricle appears normal in size and systolic function.
Right ventricle left ventricle end diastolic basal diameter ratio 1 the right ventricular outflow tract is considered enlarged when the measured diameter in the parasternal long axis exceeds 3 3 cm or when the measured diameter exceeds 2 7 cm in the distal rvot as measured in the basal parasternal short axis view.
