ABSTRACT

Introduction. The levo-transposition of the great arteries (L-TGA) is a congenital defect with not many probabilities of surgical correction in our country. Among the available therapeutic alternatives, the double switch surgery (DSS) offers a physiological and safe correction for the infant in the short and long term.
Clinical presentation. Two cases of L-TGA with severe tricuspid regurgitation, one of them associated to Ebstein anomaly, are presented. Pulmonary banding was performed in both cases in preparation for the DSS.
Comments. The DSS is considered a novel and safe alternative because it offers an anatomic/ functional L-TGA correction and avoids the problems associated with the classic intervention. Although these two cases are the first succesfully performed in the Fundación Cardiovascular de Colombia (Bucaramanga – Colombia), they requiere a long follow-up period with special emphasis in the observation of the right atrial obstructive gradients and the tricuspid regurgitation behavior, both of which can produce venous congestive signs.
