Between February 1999 and November
1999,33 patients（age 67.0±7.6years old）underwent off-pump CABG
using coronary shunt tubes. The number of graft anastomoses per
patient was 2.8±0.8. The operative mortality was 0%. There was
no incidence of on-pump conversion, low cardiac output syndrome,
IABP insertion, mediastinitis or stroke. The maximum CPK-MB during
the perioperative period was 25.9±18.8IU/l. One patient had perioperative
myocardial infarction probably due to native coronary artery
spasm. In patients with off-pump CABG, the intubation time, the
ICU stay and the hospital stay were shorter. The number of patients
who were extubated in the operating room was higher and the cost
was lower than those with on-pump CABG. An early phase study
revealed patency ratios of 85%（the previous term）and 97%（the
latter term). Off-pump CABG is a safe and effective means of
revascularization with no mortality, minimal morbidity and good
short-term patency.
