Myocardial dissection in right ventricular infarction: Two-dimensional echocardiographic recognition and pathologic study

mPA sinus rhythm, and its absence during atria1 fibrillation in the same patient. Furthermore, systolic forward flow through the pulmonary valve in this patient can be assumed to be caused mainly by systolic protrusion of the interventricular septum toward the right ventricular cavity (paradoxical motion of the interventricular septum), since the right ventricle did not appear to contract. In addition, it is assumed that respiration also has a major influence on the pulmonary circulation in Uhl’s anoma-
