Table 1 Types of paradoxical septal motion. RV = right ventricular; RVOT = right ventricular outflow tract; D-TGA = dextroposed transposition of the great arteries; ccTGA = congenitally corrected transposition of the great arteries
Paradoxical septal motion | ||
|---|---|---|
Systolic | Systolic and diastolic | Diastolic |
Left bundle branch block | RV volume overload (left to right shunts, tricuspid and pulmonary regurgitation) | Pericardial constriction |
Antero-septal infarction | RV pressure overload (RVOT obstruction, pulmonary hypertension, D-TGA after atrial switch procedures and ccTGA end systole) | Arrhythmogenic RV cardiomyopathy |
