Background: Evaluating donor heart as accurately as possible upon the organ procurement would help lead careful post-transplant heart management. Our institution (National Cerebral and Cardiovascular Center, Osaka, Japan) has sent a transplant cardiologist upon the organ procurement for evaluating a donor heart ever since our first case of heart transplantation.
Methods: Thirteen consecutive bedside echocardiograms obtained from donors upon the organ procurement and post-transplant echocardiograms obtained from their recipients were retrospectively reviewed. The impact of donor echocardiograms on their recipients' post-transplant time course was analyzed and both the donor echocardiographic parameters and their recipients' parameters within 1 week after the heart transplant were compared.
Results: Both the left ventricular end-diastolic diameter and the ventricular wall thickness of donors correlated well with those parameters of their corresponding recipients (r(2) = 0.740, p<0.0001, r(2)=0.704, p < 0.0001, respectively). The information on coronary flow of the donor heart with risk factors for ischemic heart disease was useful for judging the availability for heart transplantation. The information on the pre-existing localized wall motion abnormality of donor hearts was useful for ruling out a possibility of rejection and other causes of wall motion abnormality after transplantation. The mean time required for bedside echocardiography for the donor heart was only 3.7 min. None of the recipients either developed primary graft failure or required treatment for cellular rejection.
Conclusions: Detailed observation of donor hearts by bedside echocardiograms upon the organ procurement is of clinical benefit.
