Implante de stent na via de saída de ventrículo direito: alternativa à paliação cirúrgica convencional?

The use of intravascular stents in children with congenital heart disease is well established, however the use of palliative percutaneous therapy instead of a conventional surgery remains uncertain. We present three cases of critical right ventricular outflow tract (RVOT) obstruction treated with stenting to expand the RVOT. Stenting was successful in all three cases, reestablishing pulmonary flow into the pulmonary arteries and improving oxygen saturation.
