BACKGROUND: There are limited data on the use of percutaneous revascularization techniques for transplant coronary artery disease (CAD).
METHODS: Medical records and angiographic results for cardiac transplant patients undergoing percutaneous revascularization at Emory University Hospital were reviewed. Procedural results, results of angiography 4Eth 6 months after intervention, and clinical follow-up were recorded.
RESULTS: Nineteen patients underwent 51 interventions. Thirty-eight lesions (75%) were de novo and 13 (25%) were restenotic. All patients had hypertension, 37% had diabetes, 79% had elevated lipid levels, and 53% had at least one episode of moderate to severe allograft rejection (grade 3A or greater). The primary procedural success rate was 100% with no major complications. Six-month restenosis rate (defined as > 50%) was 49%. At 23+/-17 months follow-up, 6 patients were dead or retransplanted (31%). Thirteen patients were alive without retransplantation (9 New York Heart Association class I, 3 class II, 1 class III).
CONCLUSION: Percutaneous revascularization is safe and has a high initial procedural success rate in patients with transplant CAD. However, the restenosis rate in this population remains higher than reported for atherosclerotic coronary disease and the long-term prognosis remains poor.
