    Objective To summarize the early outcomes and clinic al experience of off-pump coronary artery bypass grafting (off-pump CABG) afte r off-pump coronary endarterectomy (CE) for patients with diffused coronary art ery disease. Methods From May 2003 to November 2006,83 patients with diffu sed coronary artery disease underwent CE without cardiopulmonary bypass and off-pump CABG. There were 61 males and 22 females with age ranged from 55 to 80 ye ars (65±7 years). There were 7 patients in Canadian Cardiac Society(CCS) an gina classⅡ,20 patients in class Ⅲ,and 56 patients in class Ⅳ. 36(43.4%) pat ients had history of myocardial infarction. Coronary angiogram revealed th at 5 patients had double vessels disease, and other 78 patients had triple ves s els disease with 16 left main stem disease. The left ventricular ejection fract ion(LVEF) ranged from 25% to 65% (51%±16%). One hundred and ten endarter e ctomies were performed in 83 patients totally which included 67 in left anterior descending artery(LAD),9 in circumflex artery and 34 in right coronary artery . Twenty patients received onlay venous patch after CE in LAD and then grafte d by internal mammary artery (IMA) on the patch. There were 83 left IMA, 2 radia l arteries, others were great saphenous veins, the mean number of grafts was 3.9 ±1.2. Results There was no death in all patients. Intraoper ative graft flowmeter was used to check the flow in the grafts before chest cl osure. One hundred and one (92%) out of 110 grafts after CE showed a satisfactor y grafts flow(22±16ml/min) intraoperatively. Four patients had perioperative myocardial infarctions but none had hemodynamic changes. All patients discharged uneventfully. Seventyfive patients (90.4%) had 8 to 50 months followup with no angi na reoccurrence. Eight patients had coronary angiogram from 3 to 29 months af ter operation with all patent grafts to the CE coronaries. Conclusion Off-pump CABG with coronary endarterectomy is feasible and achieves surgical revascularization in patients with diffuse cor onary artery disease.
