Patients with ischemic heart disease (IHD) low ejection fraction (EF), and
congestive heart failure (CHF), are usually referred for orthotopic heart
transplantation (OHT). This study reports our experience with coronary
artery bypass grafting (CABG) in patients initially referred for OHT, and
suggests guidelines to facilitate the choice of procedure (OHT or CABG).
Between January 1990 and December 1991, 32 patients with IHD, proposed for
OHT, underwent CABG 31/32 patients were male, the mean age was 58 +/- 12
years (40 to 70). Congestive heart failure was present in all patients and
was the main symptom. The mean EF was 23 (14 to 31%), mean cardiac index
(CI) 2.4 l/min per m2 (1.6 to 3.1 l/min per m2), mean pulmonary artery mean
pressure (MPAP) 26 (20 to 37 mmHg) and mean pulmonary wedge pressure 16 (12
to 22 mmHg). Every patients underwent a myocardial viability study by
thallium scintigraphy (n = 32) and/or by positron emission tomography (n =
10). The perioperative mortality was 9.3% (3/32). All long-term survivors
(n = 27) are in NYHA Class II with a complete follow-up (mean 18 +/- 6
months). Ejection fraction control either by angiography (n = 15) or by
single photon emission computed tomography (n = 12) showed an increase of
up to 38% (22%-46%). Three determinant factors influenced the choice of
CABG. 1) CI > 21/min per m2, 2) MPAP < 35 mmHg. 3) Detection of
myocardial viability.(ABSTRACT TRUNCATED AT 250 WORDS)
