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
Risk Factors
Certain surgical procedures are independently associated with a higher risk of PSM:
Risk Factors Associated with an Increased Risk of PSM
- Aortic valve surgery (p=0.02)
- Mitral valve surgery (p<0.001)
- Longer cardiopulmonary bypass time (p < 0.001)
Risk Factors Associated with an Decreased Risk of PSM
- Coronary artery bypass grafting (CABG) than non-CABG surgery (p = 0.003)
- Off-pump coronary artery bypass (OPCAB)
Diagnosis
Echocardiography
