Echocardiography

There are some of these parameters, such as tricuspid, aneloplane systolic excursion. The surrogate on the echocardiography side is ejection fraction. And then currently there's a novel parameter that Dr. Kumar would get a little bit, will describe it a little bit more in detail. Global longitudinal strain and RV free wall strain,. These are the more novel approaches to determining this function of the right ventricle.
