Cardiac transplantation using extended-donor criteria organs for systemic amyloidosis complicated by heart failure.Maurer MS, Raina A, Hesdorffer C, Bijou R, Colombo P, Deng M, Drusin R, Haythe J, Horn E, Lee SH, Marboe C, Naka Y, Schulman L, Scully B, Shapiro P, Prager K, Radhakrishnan J, Restaino S, Mancini D Department of Medicine, Divisions of Cardiology, Columbia University Medical Center, New York, NY 10032, USA. msm10@columbia.edu BACKGROUND: Systemic amyloidosis complicated by heart failure is associated with high cardiovascular morbidity and mortality. Heart transplantation for patients with systemic amyloidosis is controversial due to recurrence of disease in the transplanted organ or progression of disease in other organs. METHODS: All patients with systemic amyloidosis and heart failure referred for heart transplant evaluation from 1997 to 2004 were included in this retrospective cohort analysis. An interdisciplinary protocol for cardiac transplantation using extended-donor criteria organs, followed in 6 months by either high-dose chemotherapy and stem cell transplantation for patients with primary (AL) or by orthotopic liver transplantation for familial (ATTR) amyloidosis, was developed. Survival of the transplanted amyloid cohort was compared to survival of those amyloid patients not transplanted and to patients transplanted for other indications. RESULTS: A total of 25 patients with systemic amyloidosis and heart failure were included in the study; 12 patients received heart transplants. Amyloid heart transplant recipients were more likely female (58% vs. 8%, P=0.02) and had lower serum creatinine (1.3+/-0.5 vs. 2.0+/-0.7 mg/dL, P=0.01) than nontransplanted amyloid patients. Survival at 1-year after heart transplant evaluation was higher among transplanted patients (75% vs. 23%) compared to patients not transplanted (P=0.001). Short-term survival posttransplant did not differ between transplanted amyloid patients and contemporaneous standard and extended-donor criteria heart transplant patients (P=0.65). CONCLUSIONS: Cardiac transplantation for amyloid patients with extended-donor criteria organs followed by either stem cell or liver transplantation is associated with improved survival compared to patients not transplanted. Short- to intermediate-term survival is similar to patients receiving heart transplantation for other indications. This clinical management strategy provides cardiac amyloid patients a novel therapeutic option. Published 13 March 2007 in Transplantation, 83(5): 539-45.
