    Abstract:
    1. The frequency of heart and lung transplantation has increased dramatically over time. The number of heart transplants increased 170% between 1968 and 1981. Exponential increases began in 1982 and increased through 1990, as evidenced by a 1,835% growth in the number of procedures performed during those years. In more recent years, heart transplant numbers have leveled off, with only an 8% increase in the last 3 years. Lung transplant procedures have grown significantly in the short period of time between 1987 (n = 18) and 1993 (n = 669). 2. Since the beginning of the ISHLT Registry in 1968 the number of thoracic transplant programs has increased 7,767%, from 3 to 236. 3. The most frequently reported indications for thoracic transplantation include: coronary artery disease (43.4%) for heart, cystic fibrosis (39.5%) for double-lung, emphysema/COPD (40.2%) for single-lung and primary pulmonary hypertension (38.3%) for heart-lung. 4. The majority of heart transplant recipients are at least 18 years old (89.5%), male (78.2%), and White (83.8%). The majority of lung transplant recipients are at least 18 years old (93.7%), female (53.2%), and White (91.3%). 5. One-year survival over time has almost doubled for all types of thoracic transplantation, with increases from 47.7% in 1968-79 to 81.6% in 1993 for heart; 35.3% in 1987 to 67.1% in 1993 for lung; and 40% in the early 1980s to 73% in 1993 for heart-lung. 6. Long-term 10-year survival rates were 33.5% for heart and 5.6% for heart-lung transplant recipients. Five-year survival for lung recipients was 37%. 7. Male-to-male donor-to-recipient gender-match heart transplant patients exhibited slightly higher survival (4-5%) than other match pairs from one to 5 years posttransplant. Female-to-male combinations in lung transplant recipients exhibited slightly higher survival (4-8%) at 3 years than other match pairs. 8. There was no significant difference in 5-year survival for donor hearts procured from local, intraregional, or interregional sources. Lungs procured from interregional sources exhibited an 8-10% advantage over local and intraregionally procured organs at 3 years posttransplant.
