Allograft scarcity limits the clinical application of allograft transplantation. Domino heart transplantation has been described as a feasible option in acquiring additional heart allografts.
1 New descriptive operative techniques and options in widening the donor pool are, however, limited in the recent literature. We are presenting the case of a patient who had pulmonary hypertension because of uncorrected persistent atrial and ventricular septal defects (ASD, VSD) and therefore was not suitable for primary heart transplantation. This patient underwent combined heart-lung transplantation after 11 months on the waiting list. The autochthonous heart with the ASD and VSD was replaced, surgically repaired in a backtable maneuver, and transplanted into a patient in New York Heart Association class IV.
Yacoub and others demonstrated in their transplant programs that domino cardiac transplantation is a successful and feasible option for acquiring additional allografts with results comparable to those of conventional allotransplantation.
2-4 In domino cardiac transplantation, usually the normal heart of a heart-lung transplant recipient is implanted into another recipient with end-stage heart failure. In addition to this previously described surgical scenario, we are reporting that an allograft that caused the Eisenmenger syndrome in the heart-lung recipient was repaired in a backtable procedure and successfully implanted as an allograft. A pathophysiological discussion is also included.
Clinical summary
Heart-lung recipient
A 48-year-old woman with severe pulmonary hypertension resulting from a perimembranous VSD (18 mm in diameter) and a persistent oval foramen with Eisenmenger syndrome was evaluated for heart-lung transplantation. The cardiac disease had been diagnosed at 27 years of age. The symptoms became severe 1 year before transplantation (New York Heart Association class III-IV). Right heart catheterization revealed a
