Right ventricular diastolic collapse occurs in early diastole when the right ventricular volume and pressure are a their lowest levels in patients with cardiac tamponade. Right ventricular diastolic collapse can be observed in the PSAX, PLAX, A 4CH and the subcostal 4CH. Web(ii) Early diastolic collapse of right ventricular outflow tract12 (Fig. 3c). This is best visualized in parasternal views. This happens because during early diastole the intraventricular pressures fall below the intrapericardial pressure. As right ventricular outflow tract is thin, it collapses during early diastole. Co- csm cardiff
