Coronary by-pass for bad ventricle; adoption of "hybrid-pump" bypass.

BACKGROUND: The outcomes of on-pump and hybrid-pump bypass surgery in patients with depressed left ventricular function (EF<30%) were analyzed. METHODS: 109 patients with preoperative left ventricular ejection fraction of <30% and bypassable circumflex coronary disease were randomized in a double blind fashion to undergo hybrid-pump (combination of off-pump and on-pump) procedure (54 patients), or on-pump coronary bypass (55 patients). In patients who underwent hybrid-pump procedure only circumflex system was bypassed on-pump to shorten CPB and myocardial ischemic time. Pre- peri and postoperative variables were analyzed. RESULTS: Mean LVEF 24.4 +/- 4.8%. The patients in hybrid-pump group received less graft than others, but difference was not significant. Duration of the surgery was not different statistically between hybrid-pump and on-pump groups. A longer intraoperative duration of ischemia and extra corporeal circulation was found in on-pump group. Significant improvement in the postoperative course such as shorter mechanical ventilation, less catecholamines and IABP usage, less ICU and hospital stay, less stroke, less need for hemodyalisis and most importantly less hospital mortality was observed in hybrid-pump group. CONCLUSION: Shortening the CPB and myocardial ischemic time and avoiding related problems, adoption of hybrid-pump strategy, in patients with severely impaired LVEF and bypassable circumflex coronary disease results in better outcome than conventional on-pump bypass.

Off-pump coronary bypass for patients with concomitant malignancy.

BACKGROUND: The effectiveness and advantages of off-pump coronary artery bypass (OPCAB) for patients with concomitant malignant neoplastic disorders were analyzed. METHODS AND RESULTS: The study group comprised 368 patients who underwent OPCAB and of them 18 had concomitant malignant neoplastic disease: 14 with solitary malignant disease, 4 with low-grade lymphocytic malignancies. The age of the patients ranged from 49 to 72 years (mean 61). The mean left ventricular ejection fraction was 46.4% (range: 35-60%) and the mean number of grafts was 2.4+/-0.9. The left internal mammary artery was used in 12 patients (75%). Mean blood loss was 420+/-64 ml and the average requirement for blood transfusion was 1.1+/-0.2 units. There was no postoperative infection or in-hospital mortality. The mean length of hospital stay was 6.4+/-1.3 days. Mid-term follow-up was completed (100%) and the mean follow-up period was 22.6+/-4.1 months. All patients with a solitary malignancy underwent subsequent non-cardiac surgery with a mean interval of 16.4+/-3.3 days. Mid-term survival was 83.4%. Freedom from late cardiac events (angina, myocardial infarction, percutaneous transluminal coronary angioplasty) that required hospital admission was 92.3%. CONCLUSION: These results support the effectiveness of OPCAB, mostly as a bridge to safe non-cardiac surgery that can be crucial for long-term survival.
