ABSTRACT
Background. Long-term survival after heart transplantation is a desirable although
challenging goal.
Methods. We analyzed clinical outcomes in the cohort of 170 patients who have
undergone heart transplantation at The Cleveland Clinic Foundation and survived 10
years.
Results. We found 10-year and 15-year survival rates of 54% and 41%, respectively, in
these patients, but there was also a high incidence of complications, such as hypertension,
renal dysfunction, transplant vasculopathy, and malignancy.
Conclusions. Long-term survival following cardiac transplantation is possible although
complications are frequent. Beyond 10 years, malignancy is a major cause of death.
O
RTHOTOPIC heart transplantation (HTx) has be-
come a widely accepted therapeutic modality for
patients with end-stage heart failure. Long-term outcomes
after transplantation have improved with the advances
made in transplant candidate selection, surgical techniques,
immunosuppression, and postoperative care. The current
survival rate after heart transplantation has been reported
as approximately 50% at 10 years by the International
Society for Heart and Lung Transplantation (ISHLT) reg-
istry.

This study is undertaken to determine the long-term
(10 years) survival of patients who have undergone HTx
at our institution, and to describe their clinical status after
10 years.
METHODS
Patient Population
Between August 1, 1984 and May 31, 2004, a total of 1089 adult
patients underwent HTx at the Cleveland Clinic Foundation. To
study patients who survived beyond 10 years, we evaluated a
consecutive cohort of 325 patients who underwent transplantation
between August 1, 1984 and May 31, 1994. A total of 170 patients
survived more than 10 years. We excluded 11 patients who under-
went retransplantation during the first 10-year period.
Data Collection
Our data was retrieved from the Cleveland Clinic Foundation
Heart Transplant Database, which is approved by the Institutional
Review Board of our institution.
Immunosuppressive Regimen
Cyclosporine was administered as a part of initial immunosuppres-
sion in all of the patients included in this study. Maintenance
immunosuppression therapy consisted of cyclosporine, azathio-
prine, and steroids.
Follow-Up
Patients underwent surveillance biopsies starting at 1 week after
HTx, once weekly for the first month, every other week during the
second month, and then every 6 – 8 weeks between the 3rd and 12th
months. Subsequently, biopsy was performed every 3 months
during the 2nd and 3rd year and then every 4 – 6 months during the
4th and 5th year. Coronary angiography was routinely performed at
1 month as the baseline after HTx and then annually for follow-up
if not contraindicated. We defined significant graft coronary artery
disease (GCAD) as 50% focal or diffuse stenosis in a main
epicardial coronary artery. Minimal GCAD was defined as any
lesion 50% in any coronary artery. Echocardiography was per-
formed on 111 patients who were at 10 years after transplantation.
