Surgical treatment of pulmonary venous baffle obstruction after modified Senning procedure

Abstract A 13-year-old male was admitted to undergoing correctionof a pulmonary venous baffle stenosis (PVBS) after a modifiedSenning procedure was performed by the age of five months.Recurrent Pulmonary congestion and pneumonia episodeswere followed by echocardiography and cardiaccatheterization that confirmed PVBS. Previous catheterballoon angioplasty was attempted, and a surgical revisionwas done under cardiopulmonary bypass. The bovinepericardial patch used for augmentation of the right atrium,retracted and calcified producing PVBS. Stenotic area wasexcised and enlargement was done withpolytetrafluoroethylene membrane. Intraoperativetransesophageal echocardiogram showed relief of stenosis. Descriptors: Reoperation. Pulmonary veins. Pericardium. Resumo Paciente de 13 anos de idade, sexo masculino, submetidoa correcao de estenose de tunel das veias pulmonares (ETVP)apos cirurgia de Senning modificada realizada aos 5 meses.O quadro clinico era de congestao pulmonar ebroncopneumonias de repeticao e o ecocardiogramaconfirmou ETVP. Uma angioplastia com balao foi realizadapreviamente a correcao cirurgica com circulacaoextracorporea. A placa de pericardio bovino empregada paraampliacao do atrio direito retraiu-se e calcificou, levando aETVP. A placa foi removida e o atrio direito foi ampliadocom um retalho de politetrafluoretileno. O ecocardiogramatransesofagico intraoperatorio demonstrou reducaosignificativa da estenose.
