Caso 6/2020 – Jovem de 16 Anos, com Estenose Pulmonar Acentuada a Nível Valvar, após Corre??o de Tronco Arterial Comum pela Técnica de Barbero-Marcial no Primeiro Mês de Vida

摘要

The newborn, in heart failure with truncus arteriosus type I, underwent repair at 15 days of age, weighing 2800 g. of body weight, by the Barbero-Marcial technique. At that time, the right ventricular outflow tract was approached directly with the pulmonary trunk and a monocusp valve was placed in the pulmonary position. The evolution was adequate, with heart failure control, and he remained asymptomatic and showed normal physical development. The clinical examination ruled out residual lesions, such as pulmonary valve insufficiency. Over time, while asymptomatic, a systolic murmur was identified in the pulmonary area, of progressive intensity, together with an increasing pressure gradient in the region of the pulmonary monocusp. At 2 years of age, it was 25 mmHg; at 5 years, 34 mm Hg; at 7 years, it was 40; at 13 years it was 90 and at 16 years it was 149 mmHg. The patient did not use any specific medications.
