Long-term outcome after heart transplantation performed in the University Medical Centre Groningen

Ten years ago, there was a difference of opinion about the suitability of ventilated patients with end-stage cardiac failure for heart transplantation (HTX). Although guidelines at that time qualified mechanical ventilation as a contraindication, we thought those patients could be candidates for HTX. In the same period a number of other patients received a donor heart in our centre. In this article we describe the clinical course and survival after these procedures.

We performed a retrospective study using our post HTX database. All patients undergoing transplants in our hospital were selected. Patients underwent echocardiography, scintigraphy (MUGA), ergo-spirometry (VO₂ peak), blood tests and completed a quality of life questionnaire (SF-36). All tests were completed in the 1st quarter of 2006.

Eight patients were identified; three were mechanically ventilated at the time of HTX. All eight patients were treated according to the standard protocol. Repeated surveillance cardiac biopsies were taken. One patient died 3.5 years after HTX due to an acute myocardial infarction. Seven patients, including the three patients on a ventilator at the time of the HTX, are alive, resulting in a survival rate of 88%. The current median survival time is 126 months (range 55 to 184 months). All patients are in good cardiac condition. The SF-36 domains of social functioning and mental health show high scores, the average score of general health and vitality is moderate.

Survival of our eight transplanted patients after a median period of ten years was 88%, which is at least comparable with data from larger series. This finding suggests that HTX can be performed effectively and safely in a low volume centre. The finding that all three patients on a ventilator prior to HTX are alive is remarkable. It appears that mechanical ventilation is not always an absolute contraindication for HTX.
