The septum is flattening during diastole and is maximal at the end of diastole. Ventricular septal flattening can occur with right ventricular overload (ie. TR) where the ventricular septum flattening is maximal at the end of diastole. Diastolic septal flattening can occur with ASD and VSD repairs. Diastolic septal flattening can also occur with constrictive pericarditis. Diastolic septal flattening can also occur in primary pulmonary hypertension, although it is preceded by systolic flattening (paradoxial septal motion) and the diastolic septal flattening occurs only in early diastole.
