The value of echocardiographic left ventricular rotational body volume analysis in the assessment of patients with pulmonary hypertension

A new sonographic measure of left ventricular volume change using mathematical rotational volume calculus, particularly the ratio of left ventricular end-systolic volume, could be a useful additional tool for assessing severity and risk stratification in patients with PH. When accurate estimation of pulmonary artery pressure via tricuspid regurgitation pressure gradients is challenging, the addition of this information improves the utility of Echo in the assessment of PH patients.
