IMAGE BASED EVALUATION OF RIGHT VENTRICULAR MYOCARDIAL STRAIN MECHANICS USING 4D AND 2D ECHOCARDIOGRAPHY

We tested the feasibility of four-dimensional echocardiography (4DE) for evaluation of RV mechanics. Eight freshly harvested porcine RV models were studied. Latex balloons were sewn into the mitral annulus and connected to a pump to create a pulsatile motion in the RV. Eight sonomicrometry crystals
