The major cause of early death after heart transplantation is graft
failure. In 99 consecutive heart transplantations two protocols of
myocardial protection were employed. In group 1 (n = 38) initial cold
crystalloid cardioplegia combined with cold saline storage and peroperative
surface cooling was used. In group 2 (n = 61) cold crystalloid cardioplegia
was injected initially and cold blood cardioplegia (Buckberg) was infused
every 30 min as soon as the graft arrived in the operating room. No surface
cooling was used. Warm blood cardioplegic reperfusion was administered
before removal of the aortic clamp. There were 8 early (within 30 days)
deaths in group 1 and 6 in group 2 patients. In group 1 there were 5
cardiac deaths against 3 in group 2. Mean ischemic time was 153 +/- 37 min
in group 1 and 158 +/- 51 min (p greater than 0.05) in group 2. The
post-transplantation need for catecholamines was ten times higher in group
1 patients than in group 2. The first endomyocardial biopsy (after 1 week)
showed cytologic lesions compatible with ischemia in 40% of group 1 and
only 9% in group 2 patients. We conclude from this initial experience that
intermittent cold blood cardioplegia and warm blood cardioplegic
reperfusion are useful in heart transplantation in restoring the damage
suffered by the graft during brain death and graft storage.
