Left-Right Ventricular Interactions in Pediatric Aortic Stenosis: Right Ventricular Myocardial Strain before and after Aortic Valvuloplasty

RV strain was normal or reduced in compensated aortic stenosis and was not correlated with LV strain. The change in RV strain was variable among patients after valvuloplasty, with improvement in RV midwall longitudinal strain.
