From: Noninvasive right ventricular work in patients with atrial septal defects: a proof-of-concept study
Process for calculating right ventricular myocardial work. A Evaluating the right ventricular longitudinal strain. B Tracking the TR velocity-time integral to assess the mean gradient pressure between the right ventricle and atrium. C Identifying the event timing of the tricuspid valve and pulmonary valve. D Obtaining right ventricular myocardial work by the right ventricular pressure-strain loop
