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

ABSTRACT

Multiple cardiac masses were incidentally detected in a neonateon twelve day of life. Failure to thrive, feeding difficulty andsevere dynamic right ventricular outflow tract obstructiondeveloped at 7 months of age. Surgical resection of intracardiacmasses relieved symptoms and histological studies confirmedrhabdomyoma. Progressive increase in the size ofrhabdomyoma during infancy is an uncommon presentation andsurgery can be life-saving.
