title: [Left ventricular hypertrophy simulating an intracavitary tumor. Echocardiographic diagnosis].
abstract: We report a case of a 14 month old infant with severe stenosis of the pulmonary valve in whom the angiographic image suggested the presence of a right ventricular (RV) tumor mass. The patient was admitted because of clinical manifestations of heart failure. Right heart catheterization demonstrated a transvalvular pulmonary gradient and filling defects in the infundibulum compatible with an intracavitary mass. Two dimensional and Doppler echocardiography confirmed pulmonary stenosis and showed that the mass corresponded to hypertrophy of the anterior RV wall. The combination of two dimensional and Doppler echocardiography are the indicated techniques in differential diagnosis of RV tumor masses and RV hypertrophy secondary to severe pulmonary valve stenosis.
