Orthotopic heart transplantation with concurrent coronary artery bypass grafting or previous stent implantation.

We describe three cases of donor hearts with preexisting coronary artery disease already diagnosed prior to transplantation: two were treated by coronary artery bypass grafting during the transplant procedure and one by angioplasty with stenting during the donor screening angiography. All three donor organs would otherwise have been rejected, depriving potential recipients of organ transplantation. All patients had an uneventful post-operative course with follow-up completed 22, 40 and 43 months after orthotopic transplantation showing patency of the stent and bypass grafts in the early (1 and 9 months) and late (22, 24 and 37 months) coronary angiography. Our results suggest that in this era of acute organ shortage donor hearts requiring bypass or stenting, which form a small but significant donor subgroup, can be used effectively and safely when matched to the recipients' age and medical condition.

[Advances and perspectives in mechanical heart assist].

Mechanical circulatory support devices were first developed to permanently replace the failing heart. Today, however, the majority of these devices are used as a mechanical bridge in patients awaiting heart transplantation. With this indication, important information on using mechanical assist devices has been assembled. We present our experience, which has been gained since 1987 in the area of patient selection, post-implant patient care and device maintenance. More than 450 patients have since been implanted with assist devices at our institution. Mechanical circulatory support may not only lead to recovery from secondary organ failure, but also to myocardial remodeling and recovery of the heart function in some patients. Additionally we report our experience with a newly developed implantable axial flow pump and discuss the possibility and costs of permanent support in some patients.
