ABSTRACT Transplant vasculopathy significantly limits the survival of cardiac transplant patients and occurs in 50% of patients by 5 years posttransplant. We report our experience with six cardiac transplant patients who underwent intracoronary brachytherapy for in-stent restenosis. At four centers, six patients underwent intracoronary radiation for in-stent restenosis. All patients received extended antiplatelet therapy with clopidogrel and aspirin. Follow-up angiography was performed in all patients. Two of the six patients underwent subsequent target lesion revascularization. Patient 1 presented with total occlusion of her radiated lesion. She had a complex procedure requiring stenting for a dissection after the radiation dwell. Patient 2 had high-grade restenosis following brachytherapy. Patient 3 had a 50% restenotic lesion. Patients 4, 5, and 6 had follow-up angiography that showed no evidence of restenosis. There are few good options to treated accelerated transplant vasculopathy. Radiation therapy may be a viable option in this difficult patient population.

    ABSTRACT: High risk angioplasty with drug eluting stent placement into an unprotected left main coronary artery in a heart transplant recipient with allograft vasculopathy is reported. Ten month angiographic follow up is reported. The literature is reviewed and current methods of revascularisation are described in detail. This is the first report of drug eluting stent use in this clinical situation.

    ABSTRACT: Cardiac transplantation is a highly effective therapy for selected patients with end-stage cardiac disease. The management of the patient after heart transplant involves three main strategies: optimization of immunosuppressive therapy, prevention of complications resulting from the transplant or the immunosuppressive agents, and treatment of those complications when they arise. For most patients, optimal current immunosuppression in the first year after transplantation consists of combination therapy with a calcineurin inhibitor (eg, cyclosporine or tacrolimus), corticosteroids, and an antimetabolite agent (eg, azathioprine or mycophenolate mofetil). Ideally, the corticosteroid is weaned and discontinued 1 to 2 years following transplantation and the patient is managed chronically with a two-drug immunosuppressive regimen. The major complications that occur following cardiac transplantation include infection, hypertension, diabetes, dyslipidemia, osteoporosis, graft coronary disease, renal insufficiency, and malignancy. Preventive efforts focused on infection, osteoporosis, renal insufficiency, and malignancy include minimization of immunosuppression. Once established, treatment of any of the above conditions generally relies on standard pharmacologic therapies; however, an understanding of potential drug interactions is critical. In addition, although standard nonpharmacologic therapies may be used to treat several of these conditions, one must be cognizant of special issues related to the post-transplant state.
