From April 1994 until June 1996, we exclusively utilized the integrated myocardial management (IMM) proposed by Buckberg et al. at UCLA. Two hundred sixty-two consecutive patients undergoing open heart surgery at our hospital were divided into 2 groups, the non-IMM (n = 49, from July 1993 until March 1994) and the IMM (n = 213, from April 1994 until June 1996) groups. Although many older and more severely ill patients were treated with IMM, acceptable clinical outcomes with comparable safety and efficiency were obtained. Shorter durations of total cardiopulmonary bypass (CPB) and aortic cross-clamping (AXC) were needed in the IMM group despite there being many more procedures undertaken during a single cross-clamp period.
