Regressão tardia espontânea de tumor obstrutivo na valva mitral / Late spontaneous regression of obstructive tumor in the mitral valve

RESUMO

O rabdomioma cardíaco raramente é encontrado na valva mitral, porém, embora de grande dimensão (15x14 mm), causando até obstrução a esse nível nos primeiros meses de vida, observou-se a involução total e espontânea do mesmo, iniciada com 68 meses, e tornando-se progressivamente menor até completar 14 anos de idade.

ABSTRACT

Cardiac rhabdomyoma is uncommonly found in the mitral valve. However, in the case reported, although the tumor was large (15x14 mm) and even caused obstruction at this level in the first months of life, its complete and spontaneous regression was observed as from 68 months of age, with progressive reduction until the patient was 14 years old.
