Overview
Paradoxical septal motion is defined as movement of the interventricular septum away from the left ventricular free wall during systole which is the opposite of its normal movement which is inward toward the left ventricle / or the left ventricular free wall during systole.
Causes
- Arrhythmogenic RV dysplasia
- Atrial septal defect
- Following heart surgery. There may be altered LV function and lack of restraint on the pericardium if it is opened.
- Pericardial effusion (large)
- Pulmonary hypertension
- Right ventricular hypertrophy
- Right ventricular volume overload
Diagnosis
Echocardiography
