Comparative Study
The University of Ottawa Heart Institute Cardiac Transplant Program: the first 100 transplants. A pathologic study of the explanted hearts.
Since 1984, 122 orthotopic heart transplants have been performed at the University of Ottawa Heart Institute. Of the 114 adult patients, 100 (87.8%) were males and 14 (12.2%) females, with mean ages of 45.8 and 47.9 yr, respectively. The hearts of these adults were pathologically diagnosed as chronic ischemic heart disease (CIHD) in 55 (48.2%), acute ischemic heart disease (AIHD) in 17 (14.9%), dilated cardiomyopathy (DC) in 30 (26.3%), valvular heart disease in five (4.4%), congenital heart disease in three (2.6%), myocarditis in three (2.6%), and other in one (0.9%) of the cases. ⋯ The ventricular diameters were greater in DC than in CIHD or AIHD (p less than 0.01) and greater in CIHD than in AIHD (p less than 0.01). The mean LV cavity volumes were 158, 94, and 200 ml in CIHD, AIHD, and DC, respectively, with DC greater than in CIHD or AIHD (p less than 0.01) and CIHD greater than in AIHD (p less than 0.01). The relative differences in AIHD compared to CIHD and DC are referrable to the shorter duration of disease in the acute ischemic group.2+ off
