Repair of congenital pulmonary venous stenosis with living autologous atrial tissue.
Repair of localized bilateral congenital pulmonary venous stenosis with living autologous atrial tissue was accomplished in two patients, 3 and 4 months of age. The tip of the left atrial appendage was opened and used as an onlay patch to widen the stenotic area of the left pulmonary veins, leaving a double pathway for venous return. A flap of interatrial septum was evaginated through an incision in the right side of the left atrium and used as an onlay patch to widen the stenotic area of the right pulmonary veins. Effective relief of obstruction was demonstrated by nearly normal postrepair pulmonary artery pressure in each and early postoperative angiography in one. Although we believe this method of repair will increase the probability of a lasting result, further experience and subsequent late reevaluation are needed to demonstrate its long-term effectiveness.
