Myocardial infarction due to myocardial tissue embolism of the right
coronary is a rare cause of early graft failure. We report one case with
such a complication, in a 44-year-old man who was transplanted with a graft
from a 32-year-old male donor. Prolonged refractory cardiogenic shock
developed after orthotopic heart transplantation. A right coronary artery
bypass graft was performed and the patient was supported with a
biventricular assist device for 69 h. Despite that, no improvement of the
graft contractility was observed and the patient could not recover from
shock. Pathologic examination showed inferior and septal acute infarction.
An embolus of myocardial tissue was completely occluding the first portion
of the right coronary artery. The tissue probably came from suture lines of
the left atrium.
