Pulmonary Vein Extension for Large Left Atrium Size Mismatch During Heart Transplantation

Abstract

In cases with a large recipient left atrium (LA), matching of the donor and recipient anastomoses can be challenging. In the presented case, this is addressed by reducing the circumference of the recipient LA cuff by extending the pulmonary veins. The inferior pulmonary veins were extended by making neopulmonary veins using the remnant recipient LA cuff; the circumference of the recipient LA cuff could then be reduced to easily make an anastomosis. This new technique could be an alternative method to resolve LA size discrepancies in orthotopic heart transplantation.
