Description
Summary:We present a case of a 19 year-old female patient, with tetralogy of Fallot and hypoplastic pulmonary ring. Diagnosis was performed by echocardiography and cardiac catheterization. The surgical repair was performed at the age of 2 years old. A right ventricular outflow tract remodeling was performed using a porcine pulmonary bicuspid prosthesis. The patient presented a uneventful follow-up during 17 years. Postoperative assessment has shown: mild pulmonary insufficiency and mild pulmonary ventricle gradient, satisfactory right ventricular performance and prosthesis not presenting calcification. This is an option to correct the tetralogy of Fallot adopted by our Institution in the last two decades.<br>É apresentado o caso de uma paciente de 19 anos de idade, sexo feminino, portadora de tetralogia de Fallot com anel pulmonar hipoplásico. O diagnóstico foi feito com ecoDopplercardiograma e cateterismo cardíaco. A correção cirúrgica foi realizada com 2 anos de idade. Para a reconstrução da valva pulmonar e via de saída do ventrículo foi utilizada prótese bivalvular pulmonar porcina. A paciente teve boa evolução clínica durante 17 anos. A avaliação pós-operatória demonstrou: discreta insuficiência pulmonar, discreto gradiente transvalvar pulmonar, desempenho do ventrículo direito preservado e prótese pulmonar sem calcificação. Esse é o procedimento adotado pela nossa Instituição para a correção da tetralogia de Fallot, nos últimos 20 anos.
