Cardiac Rhabdomyoma Causing Progressive Dynamic Severe Right Ventricular Outflow Tract Obstruction in an Infant.

Multiple cardiac masses were incidentally detected in a neonate on twelve day of life. Failure to thrive, feeding difficulty and severe dynamic right ventricular outflow tract obstruction developed at 7 months of age. Surgical resection of intracardiac masses relieved symptoms and histological studies confirmed rhabdomyoma. Progressive increase in the size of rhabdomyoma during infancy is an uncommon presentation and surgery can be life-saving.
