Beating heart versus conventional single-vessel reoperative coronary artery bypass

BACKGROUND: Reoperative (redo) coronary artery bypass grafting (CABG) with cardiopulmonary bypass (on-pump) is associated with a higher morbidity and mortality than first-time CABG. It is unknown, however, whether CABG without cardiopulmonary bypass (off-pump) may yield an improved clinical outcome over conventional on-pump redo CABG. METHODS: We compared the perioperative outcomes of patients with single-vessel disease who underwent on-pump (n = 41) versus off-pump (n = 91) redo CABG between April 1992 and July 1999. The two groups were similar with respect to baseline characteristics and risk stratification: mean Parsonnet scores were 26 +/- 9 for on-pump versus 24 +/- 8 for off-pump patients (p = nonsignificant). RESULTS: On-pump redo patients had a higher rate of postoperative transfusions (58% on-pump versus 27% off-pump, p = 0.001), prolonged ventilatory support (17% on-pump versus 4% off-pump, p = 0.03), and a higher rate of postoperative atrial fibrillation (29% on-pump versus 14% off-pump, p = 0.04). On-pump redo CABG was also associated with prolonged postoperative length of stay (8 +/- 4 days on-pump versus 5 +/- 2 days off-pump, p < 0.001). In-hospital mortality was significantly higher in on-pump than in off-pump patients (10% versus 1%, p = 0.03). CONCLUSIONS: Single-vessel off-pump redo CABG can be performed safely with a lower operative morbidity and mortality than on-pump CABG and an abbreviated hospital stay compared with conventional on-pump redo CABG.     

Off-pump redo coronary artery bypass grafting via left thoracotomy.

OBJECTIVE: We evaluated the usefulness of off-pump coronary artery bypass grafting (CABG) via left thoracotomy (LT) in redo coronary revascularization. METHODS: Over the past 23 years, 21 patients (2.3%) underwent redo coronary revascularization in our hospital. The period between the first and the redo surgeries was 9.1+/-4.4 years. They were divided into two groups according to the method of surgical approach in the redo CABG: re-median sternotomy group (RMS group, n=12) and LT group (n=9). RESULTS: In the RMS group, five of 12 patients suffered prolonged postoperative respiratory failure with ventilatory support, and the RMS patients stayed in the hospital for a significantly longer period of time than the LT patients. Four patients (19.0%, 4/21), who were all in the RMS group, died during the hospitalization. In the LT group, there were no hospital deaths and no cases of respiratory failure. CONCLUSION: Redo CABG via LT provided acceptable and satisfactory surgical results. As it is expected that the number of emergency reoperative surgical cases will increase, the LT approach may be useful for rapid exposure of the target coronary artery without causing significant myocardial damage.     

高风险冠心病患者接受体外或非体外循环冠状动脉旁路移植术的临床对比研究

目的比较体外循环冠状动脉旁路移植术（on—pump coronary artery bypass grafting，on—pump CABG）和非体外循环冠状动脉旁路移植术（off—pump CABG）治疗高风险冠心病患者的临床疗效。方法2003年10月～2007年10月，共对290例高风险[心脏手术风险评估欧洲系统（EuroSCORE）≥6分]冠心病患者实施CABG术，其中on—pumpCABG140例，offpumpCABG150例。比较2组手术死亡率、再血管化指数、桥血流量、呼吸机支持时间、二次开胸率、引流量、输血量及肾功能变化。结果2组在死亡率、再血管化指数、桥血流量、二次开胸率、术后脑梗塞率和心房纤颤率方面无统计学差异（P〉0．05）。与on—pumpCABG组相比，off-pumpCABG组呼吸机支持时间短[（4．8±1．9）h vs（8．9±2．1）h，t=17．453，P=0．000]，引流量少[（660±111）ml vs（660±111）ml，t=17．173，P=0．000]，输血量少[（270±77）ml vs（510±144）ml，t=17．861，P=0．000]，肾功能损害少[2．0％（3／150）VS7．9％（11／140），X^2=5．407，P=0．020]。结论较on—pump CABG，off-pump CABG治疗高风险冠心病患者的疗效同样确切，并且能显著减少呼吸机使用时间、引流量、输血量以及肾脏损害，更加适用于高风险冠心病患者。     

Efficacy of off-pump coronary artery bypass grafting for the patients on chronic hemodialysis

OBJECTIVE: Coronary artery bypass grafting (CABG) under a beating heart is reported to be less invasive and promise earlier recovery. This study was performed to evaluate the efficacy of off-pump CABG in patients with end-stage renal failure. METHODS: Isolated CABG was performed on 40 hemodialysis patients at Shin-Tokyo Hospital Group between September 1, 1993, and December 31, 2000. Among them, off-pump CABG was performed in 16 and on-pump CABG in 24. Their preoperative, perioperative, and follow-up data were retrospectively collected. RESULTS: Patient's demographics and coronary risk factors were similar in off-pump and on-pump groups. The mean number of bypass grafts was 1.9 +/- 1.1 in the off-pump group and 2.8 +/- 1.1 in the on-pump group (P < 0.05). Blood transfusion was significantly less frequent in the off-pump group than in on-pump group. Postoperative complications were more frequently observed in the on-pump group (7.1% off-pump vs 25.0% on-pump). There were two hospital deaths in the on-pump group and none in the off-pump group. Postoperative intubation time, ICU stay, and hospital stay were significantly shorter in the off-pump group than in the on-pump group. Although follow-up period was short (1.1 +/- 0.7 years), no cardiac events occurred in the off-pump group. CONCLUSIONS: Off-pump CABG for hemodialysis patients is safe and useful and it enables early recovery. Postoperative cardiac events were controlled effectively during the short period of follow-up.     

Off-pump coronary artery bypass

OBJECTIVES: Off-pump coronary artery bypass grafting (CABG) on the beating heart has become popular procedure in cardiac surgery and its initial results appeared favorable. We report our early and mid-term results of off-pump CABG performed at Shin-Tokyo Hospital. METHODS: Medical records of patients undergoing off-pump or conventional on-pump CABG from September 1, 1996, to August 31, 1999 were retrospectively reviewed. Patients underwent off-pump CABG were further classified into 2 groups; MIDCAB (Off-pump CABG for single vessel revascularization via a small skin incision) and OPCAB (off-pump CABG mainly approached via midline sternotomy) group. Their preoperative, perioperative, and follow-up data were collected and analyzed. RESULTS: Among a total of 995 cases of CABG, 194 cases were off-pump CABG (male/female 142/52, mean age 66.9). The mean number of distal anastomoses in off-pump CABG was 1.9 +/- 0.9 (1.0 +/- 0.0 in MIDCAB and 2.3 +/- 0.7 in OPCAB), which was significantly fewer than in on-pump CABG (3.6 +/- 1.1), with p < 0.0001. Intubation time (5.3 +/- 5.7 hours in off-pump CABG vs 13.1 +/- 24.2 hours in on-pump CABG), ICU stay (1.7 +/- 1.1 vs 3.2 +/- 3.0 days), and postoperative hospital stay (14.0 +/- 7.9 vs 18.1 +/- 12.1 days) in off-pump CABG were significantly shorter than in on-pump CABG (p < 0.0001). In the off-pump CABG group, there were no in-hospital deaths and 14 major complications, fewer than in on-pump CABG (8 hospital deaths and 114 major complications). Postoperative angiography before hospital discharge was conducted in 80 patients (41.2%) and showed 2 occlusions, giving a graft patency rate of 98.6% in the off-pump group. During follow-up (0.9 +/- 0.6 year) period, there were 5 non-cardiac deaths and 20 cardiac events in the off-pump group. The actuarial survival rate at 36 months was 94.6% for off-pump CABG, showing no significant difference from the rate for conventional CABG patients (95.2% at 36 month, p = NS) The event-free rate was 84.0% at 36 months in off-pump CABG patients; however, which was less favorable than on-pump CABG patients (88.0% at 36 months, p < 0.05). CONCLUSIONS: Both in-hospital and mid-term results for off-pump CABG patients were acceptable. Isolated CABG can thus be safely performed without cardiopulmonary bypass. Advances in coronary stabilization have contributed to these improved results. The observed long-term cardiac events may be related to incomplete revascularization.

Operative mortality after conventional versus coronary revascularization without cardiopulmonary bypass.

OBJECTIVE: Off-pump coronary artery bypass (CABG) is a safe revascularization option with comparable or superior results to the conventional on-pump CABG. However, comparative analysis of the type of surgical approach on the mortality rate is largely unknown. This study sought to investigate whether CABG without cardiopulmonary bypass (off-pump CABG) is associated with lower operative mortality than the conventional on-cardiopulmonary bypass (on-pump) approach. METHODS: From October 1998 to June 2001, off-pump CABG was performed on 2477 patients and on-pump CABG was performed on 3077 patients. The patients undergoing off-pump CABG were randomly matched to on-pump patients via propensity score. Seventy-four percent of the off-pump CABG patients were matched with on-pump patients via propensity scores. A logistic regression model was used to test the difference in the postoperative mortality rate between off-pump CABG and on-pump CABG, controlling the correlation between matched sets. A multiple logistic regression model predicting the risk of mortality adjusted by risk factors of mortality and operation type was computed. RESULTS: Results from the general estimating equation showed that patients who had on-pump CABG were 1.6 (95% confidence intervals (CI)=1.2-2.0, P<0.01) times more likely to die during the first 30 days after surgery than patients who had off-pump CABG. Independent predictors of 30-day mortality identified from the multiple logistic model included on-pump CABG (versus off-pump CABG), advanced age, female gender, carotid artery disease, chronic renal failure, depressed ejection fraction, reoperative CABG, preoperative intraaortic balloon counterpulsation, and recent myocardial infarction. CONCLUSION: Excellent clinical results and a lower operative mortality rate can be achieved with the off-pump CABG technique compared with the conventional on-pump approach.     

Off-pump on-pump coronary artery bypass decision-making.

BACKGROUND: Coronary revascularization on the beating heart is an attractive to option conventional coronary artery bypass graft (CABG) but remains controversial. Our study encourages sufficient proper time for decision-making when changing CABG from off-pump to on-pump CABG. We report herein patients who changed from off-pump CABG to on-pump CABG. METHODS: A retrospective analysis of 240 patients operated upon at Cardiology Hospital of Lyon University between July 1998 and July 2000, and at one unit of Cardiac Surgery, yielded 88 patients with off-pump coronary surgery (off CAB), 21 patients changed from off-pump CABG to on-pump CABG. The other 131 patients were operated on as on-pump CABG. RESULTS: There was no operative mortality. One month postoperative mortality was only one patient out of 21 due to cardiac failure and arrhythmias. There was no significant difference in the postoperative intensive care unit (ICU) time and length of hospital stay compared with off-pump CABG. CONCLUSION: Our data suggest that a fair number of patients are potential candidates for off CAB. The only contraindication is the technical limitation or the surgeon comfort level. Changing from off CAB to on CAB can be decided for the patient's safety within the appropriate time intraoperatively without fear of more postoperative complications than with off CAB surgery.
