Atresia funcional da valva pulmonar / Functional atresia of pulmonary valve

RESUMO

Três recém-natos dentro do 1§ dia de vida, portadores de cianose, em decorrência de anomalia de Ebstein de importante repercussäo hemodinâmica, apresentavam aspecto de valva pulmonar imperfurada. Na evoluçäo clínica, verificou-se que a atresia era do tipo funcional, decorrente da baixa pressäo ventricular direita e hipertensäo no território pulmonar

ABSTRACT

Three newborn children with cyanosis due to Ebstein's anomaly of tricuspid valve with an important hemodynamic repercusssion presented features of imperforation of pulmonary valve. On the follow-up, clinical and laboratorial findings verified that pulmonary atresia was functional resulting from a combination of low right ventricular pressure and high pulmonary vascular resistance
