title: [Coronary artery bypass grafting only with arterial grafts in patients with low left ventricular function].
abstract: The advantage of arterial grafts in coronary artery bypass grafting (CABG) has been recognized and the application of these grafts has spread widely. But, the possibility of insufficient blood flow immediately after operation is pointed out. The present study was conducted in order to answer whether or not arterial grafts are applicable for patients with low left ventricular function. CABG only with arterial grafts was performed in 125 patients from December 1989 to October 1993. Comparison was made between L-group (n = 21) with a preoperative ejection fraction (EF) of 0.4 or less, and N-group (n = 104) with a preoperative EF of more than 0.4. The proportion of patients requiring postoperative IABP (33%:9%) and the incidence of mediastinitis (14%:3%) were higher in the L-group. But the mortality rate (5%:3%) or the postoperative NYHA stage (1.2:1.2) showed no significant difference between these two groups. This favorable result suggests that CABG only with arterial grafts was also useful in patients with low left ventricular function.
