We report on the ultrasound characteristics of two different intracardiac tumors in newborns. The first infant presented with multiple rhabdomyomas in the context of tuberous sclerosis. Ultrasound-based strain and strain rate analysis showed that the tumors deformed in the opposite direction from the surrounding myocardial segments. The second child presented with a large cardiac fibroma as confirmed by pathological examination. In this case strain and strain rate analysis showed the absence of deformation in the tumor. These findings suggest that this new technique could be used to differentiate between different types of myocardial tumors.
