Abstract
Background The purpose of this evidence-based consensus statement is to systematically review and meta-analyze the randomized and nonrandomized evidence comparing off-pump (OPCAB) to conventional coronary artery bypass (CCAB) surgery and to provide consensus on the role of OPCAB in low- and high-risk surgical patients. Methods and Results This consensus conference was conducted according to the American College of Cardiology (ACC)/American Heart Association (AHA) standards for development of clinical practice guidelines. The Steering Committee collated all published studies of OPCAB versus CCAB through May 2004 and developed six questions central to controversies surrounding OPCAB surgery in mortality, morbidity, and resource utilization. For mixed-risk patient populations, meta-analysis of 37 randomized clinical trials (3,369 patients, Level A) reported across a total of 53 papers, and two meta-analyses of nonrandomized trials (Level B) comparing OPCAB versus CCAB were identified. For high-risk patient populations, we performed a meta-analysis of 3 randomized and 42 nonrandomized trials (26,349 patients, Level B). Conclusion Meta-analysis of Level A and B evidence provided the basis for the following consensus statements in patients undergoing surgical myocardial revascularization: (1) OPCAB should be considered a safe alternative to CCAB with respect to risk of mortality [Class I, Level A]; (2) With appropriate use of modern stabilizers, heart positioning devices, and adequate surgeon experience, similar completeness of revascularization and graft patency can be achieved [Class IIa, Level A]; (3) OPCAB is recommended to reduce perioperative morbidity [Class I, Level A]; (4) OPCAB may be recommended to minimize midterm cognitive dysfunction [Class IIa, Level A]; (5) OPCAB should be considered as an equivalent alternative to CCAB in regard to quality of life [Class I, Level A]; (6) OPCAB is recommended to reduce the duration of ventilation, ICU and hospital stay, and resource utilization [Class I, Level A]; (7) OPCAB should be considered in high-risk patients to reduce perioperative mortality, morbidity, and resource utilization [Class IIa, Level B].

Abstract
BACKGROUND The aim of this study was to evaluate the midterm results of the initial phase of off-pump coronary artery bypass (OPCAB) surgery adoption in a single surgical unit, assessing the impact of procedural volume. METHODS Study participants were 312 patients who underwent OPCAB during the period between August 2000 and January 2005 at S. Croce Hospital. Of these patients, 126 patients with an indication selected for comorbidities or 1-vessel disease underwent OPCAB performed by 4 low-volume surgeons, and 186 unselected patients underwent OPCAB performed by a single high-volume surgeon. RESULTS OPCAB performed by low-volume surgeons was associated with less complete revascularization and less arterial conduit use. Early result analysis showed a low rate of in-hospital or 30-day adverse events. The 5-year survival was 0.88 (0.02 SE). OPCAB performance by a high-volume surgeon and complete revascularization were shown have a protective effect for midterm major adverse cardiac events (respectively, hazard ratio = 0.28, 95% confidence interval 0.11-0.74 and hazard ratio = 0.33, 95% confidence interval 0.15-0.73). CONCLUSION Our study on the initial phase of OPCAB adoption suggests a benefit on midterm outcome from surgery performed by a high-volume surgeon.

Abstract
The results of on-pump coronary artery bypass graft (CABG) surgery in 166 high-risk elderly patients (EuroSCORE 6 or more; over age 65 years [mean 71.8 years]) were compared with 176 low-risk elderly patients (EuroSCORE below 6; over age 65 years [mean 68.8 years]). There was no significant difference in hospital mortality or number of grafts between the two groups. Rates of inotropic agent use, intra-aortic balloon pump insertion and atrial fibrillation, and the duration of intensive care unit and hospital stay were significantly higher in high-risk than low-risk patients. There were no significant differences in the incidence of major complications between the two groups. The results suggest that, in selected patients, on-pump CABG can be safely performed in high-risk patients over 65 years old with no effect on mortality.

Abstract
PURPOSE Clinical evidence supports lower morbidity with off-pump coronary revascularization surgery as well as superior short- and mid-term outcomes, equivalent graft patency, and reduced cost. The purpose of this study was to compare cardiac rehabilitation (CR) outcomes between patients undergoing on-pump versus off-pump coronary artery bypass surgery. METHODS Data were retrospectively examined for patients who participated in CR between 1996 and 2004. Two hundred ninety-five patients who underwent bypass surgery and completed at least 80% of their 36 required sessions were divided into on-pump and off-pump groups. Pre- and post-CR measures included grip strength, flexibility, energy expended during class, quality of life, and self-efficacy. RESULTS Both groups were similar with respect to age, sex, ejection fraction, and mean number of grafts. There were no statistical differences between the on-pump and off-pump groups (P > .05) for weight, abdominal and hip circumferences, grip strength, flexibility, and total energy expenditure. In addition, there were no between-group differences regarding quality of life and self-efficacy. Grip strength, flexibility, and energy expenditure during class improved with CR regardless of the surgical procedure (P = .001). Quality of life (P = .001) and self-efficacy (P = .001) also improved. CONCLUSIONS The present data support the concept that although there are clinical advantages to off-pump surgery, there is no benefit over on-pump surgery regarding CR. Subsequently, patients undergoing off-pump surgery should be managed similarly as their on-pump counterparts.

Abstract
BACKGROUND It remains unclear how cardioplegic arrest affects surgical results after coronary artery bypass grafting surgery (CABG). This study compares early outcomes after on-pump beating-heart CABG and conventional CABG. METHODS From 2002 to 2005, 114 patients underwent on-pump beating-heart CABG. Multivariate logistic regression revealed five characteristics according to which technique is liable to be used: history of cerebral infarction, urgent or emergent operation, lower ejection fraction, preoperative creatine kinase, and lower number of diseased vessels. The early clinical outcome for these patients was compared against 114 conventional CABG patients, matched using a propensity score constructed with these five significant variables and with two nonsignificant variables: history of diabetes mellitus and hypertension. RESULTS On-pump beating-heart CABG significantly reduced the duration of operation and cardiopulmonary bypass, total blood loss, and peak creatine kinase (p < 0.05). The number of patients requiring additional intra-aortic balloon pump support was significantly lower in the on-pump beating-heart CABG group (2 versus 13, p < 0.01). No patients required percutaneous cardiopulmonary support after on-pump beating-heart CABG, whereas 4 patients needed it after conventional CABG. Complete revascularization was significantly lower (42.1% versus 77.2%, p < 0.0001), but in-hospital mortality was less in the on-pump beating-heart CABG group (2.6% versus 9.6%, p < 0.05). No significant difference was found in morbidity including stroke, renal failure, mediastinitis, and prolonged ventilation. CONCLUSIONS On-pump beating-heart CABG can be performed safely, including on high-risk patients. Use of cardiopulmonary bypass and the elimination of cardioplegic arrest may be of most benefit to hemodynamically unstable patients.

Abstract
BACKGROUND Off-pump coronary artery bypass (OPCAB) surgery has been successfully used in diverse patient populations and has been postulated to be safer than conventional coronary artery bypass (CCAB) surgery in some high-risk patients, including the elderly. OBJECTIVE To compare the safety of OPCAB surgery versus CCAB surgery in the octogenarian population of two large southwestern Ontario cardiac surgical units. RESULTS Two hundred thirty-six consecutive octogenarians underwent primary isolated coronary artery bypass surgery from November 2000 to March 2005. Patients undergoing OPCAB surgery tended to have higher Parsonnet scores, while patients undergoing CCAB surgery had a greater number of emergent operations. The Canadian Cardiovascular Network predicted that mortality risk was similar in both groups. In-hospital mortality was similar between groups, as was postoperative myocardial infarction and new onset of renal dysfunction. However, in the OPCAB group, there was a decreased incidence of postoperative neurological dysfunction (2.3% in the OPCAB group versus 10.5% in the CCAB group, P=0.01), in particular cerebrovascular accidents (1.5% in the OPCAB group versus 7.6% in the CCAB group, P=0.05), and a decreased incidence of prolonged intubation (5.3% in the OPCAB group versus 13.3% in the CCAB group, P=0.04). Multivariable analysis found that cardiopulmonary bypass had no significant impact on mortality or length of stay. CONCLUSIONS In octogenarian patients, OPCAB surgery is as safe as CCAB surgery in terms of mortality and major morbidity. Furthermore, a significant reduction in neurological dysfunction and prolonged intubation was seen in the OPCAB group compared with the CCAB group.

Abstract
The elderly have increasingly benefited from the advances in cardiac surgical techniques and perioperative care. Compared to the same procedures in younger patients their operations can be more technically demanding and their level of reserve leaves less margin should complications occur. The importance of using realistic indications for operations with a focus on improving the quality of their lives and of optimal preoperative preparation of patients is emphasized.

Abstract
BACKGROUND Surgical myocardial revascularization without cardiopulmonary bypass (CPB) is not new, with the first consecutive series of patients appearing in the early eighties. There has been increased interest in this alternative approach, especially in patients with comorbidities. There is controversy regarding advantages, risks, and usefulness of this method of myocardial revascularization. We herein report a consecutive series of 3,866 patients, from the first case in September 1981 to the last in November 2004, analyzing applicability, mortality, morbidity, and surgical technique. METHODS From September 1981 to November 2004, 3,866 consecutive patients were revascularized without CPB. This figure represents an overall applicability of 30.8% considering a total of 12,553 revascularization procedures performed during this time. There were 2,822 males (73%) with ages from 12 to 93 years (median, 62 +/- 14). Mean grafts per patient was 1.9, and the internal mammary artery was used in 87.3% of cases. The main indications for surgery were chronic coronary insufficiency (89% of cases) and failure of angioplasty or stenting. RESULTS Hospital mortality was 1.9%, with low incidence of cerebrovascular accident (5 cases in the entire series). Morbidity, considering major postoperative complications, occurred in 12.5% of the patients. The applicability of the off-pump technique was 18% of cases in the beginning of our experience, increasing to 49% in the last 5 years with the use of stabilizers and maneuvers to expose posterior coronary branches. CONCLUSIONS Off-pump coronary surgery is an alternative method of myocardial revascularization that should be considered for every patient. The preference of this technique over conventional revascularization should be based on the surgeon's own experience, on the patient's preoperative condition and on the coronary anatomy. Off-pump myocardial revascularization represents an important development in coronary artery surgery. Over the years it has evolved into a valid form of surgery with the same safety as the conventional operation and with more advantages in high risk patients.

Abstract
BACKGROUND The aim of this study was to compare early and mid-term outcome in patients undergoing off-pump coronary artery bypass surgery who have had complete revascularizations and incomplete revascularizations (IRs). METHODS Patient and operative data were collected prospectively for all patients who had off-pump coronary artery bypass surgery. Patients with multivessel disease were classified as having IR if the number of diseased coronary systems (left anterior descending coronary artery, circumflex and right coronary artery) exceeded the number of distal anastomoses. In-hospital outcomes, survival, and event-free survival were compared between patients with complete revascularization and IR using propensity scores to take account of differences in prognostic factors. RESULTS There were 1,479 off-pump coronary artery bypass surgery patients between April 1996 and December 2002 (30% of all coronary artery bypass graft patients), and 16.0% (237 patients) had IRs. Patients with IRs tended to be older and were female, had more extensive disease, worse dyspnea, a higher Parsonnet score, poorer ejection fraction, congestive cardiac failure, asthma or chronic obstructive airways disease, and previous cardiac surgery. The adjusted hazard ratio for patient survival with IRs versus complete revascularizations was 1.56 (95% confidence interval, 1.19 to 2.06; p = 0.001). Analyses for multiple time periods confirmed that IRs had a significantly increased risk of death, but also that the risk disappeared after the first 4 to 6 months of follow-up (p < 0.0001). CONCLUSIONS Compared with off-pump coronary artery bypass surgery patients with complete revascularizations, those with IRs have reduced survival, but only in the first 4 to 6 months after surgery. Patients' preoperative condition, rather than IR itself, may explain these findings because IRs should have mid-term as well as early effects.

Abstract
Myocardial revascularization in patients with multi-vessel coronary artery disease may be accomplished, by percutaneous interventions or surgery, either on all diseased lesions or directed to selectively targeted coronary segments. The extent of planned revascularization is often a major determinant of treatment strategy. Revascularization of all diseased coronary segments-complete myocardial revascularization-has a potential long-term benefit, but is more complex and may increase in-hospital untoward events. Revascularization may otherwise be incomplete, either because of the operator's inability to treat all diseased coronary segments or by choice of deciding to selectively revascularize only large areas of myocardium at risk. Although incomplete revascularization may negatively affect long-term outcomes, it may be, when wisely chosen, the preferred treatment strategy in selected patient categories because of its lower immediate risks. The patient's clinical status, ventricular function, and the presence of co-morbidities may orient clinical decisions in favour of incomplete revascularization.

Abstract
Coronary artery bypass surgery with beating heart (off-pump) has become more common in the last ten years allowing seven randomized studies with at least 60 patients, comparing off-pump and on-pump coronary bypass. Anaesthesia, monitoring and haemodynamic complications are described. Randomized studies concluded to less elevation of biochemical markers of myocardial and renal injury, less hydric inflation, less cerebral microemboli, reduction of homologous blood transfusions, of hospital stay and global costs. However in low risk patients no reduction in myocardial infarction, atrial fibrillation, stroke, acute renal failure, early reoperation, surgical site infection and mortality were observed. Non-randomized studies suggest a benefit in stroke and mortality in elderly patients but the possibility of incomplete revascularization remains.

Abstract
INTRODUCTION Off-pump versus on-pump coronary artery bypass surgery: it still remains a matter of debate which method results in a lower incidence of perioperative morbidity and mortality. This case-matched study evaluates the outcome of elderly patients in both groups. METHODS All patients aged 75 and older, who underwent CABG from 1998 to 2002, were examined retrospectively. They were matched according to Euroscore and the number of diseased vessels. The Student's t-test and chi-square test were used where appropriate. RESULTS 270 CABG patients were considered: 135 off-pump and 135 on-pump patients. Mean age was 78.4 +/- 3.1 versus 77.5 +/- 2.9 years, respectively. EuroSCORE was 7.11 +/- 2.3 in both groups; number of distal anastomoses per patient 1.7 +/- 0.74 versus 2.6 +/- 0.63 (p < 0.001), operation time 138 versus 177 minutes (p < 0.001). There were no significant differences in postoperative complications including hospital mortality 3.0 versus 3.7%, renal failure 8.9 versus 12.1% (new onset), acute myocardial infarction 1.5 versus 4.4% and cerebral events 0 versus 1.5%, respectively. The number of transfused packed cells was 2.6 +/- 2.8 versus 4.6 +/- 5.3 (p < 0.001). Intubation time and ICU stay were similar in both groups. CONCLUSION OPCAB is not associated with a reduction of perioperative mortality and morbidity in patients aged 75 and older.

Abstract
BACKGROUND Atrial fibrillation is the most common postoperative complication in patients undergoing coronary artery bypass grafting (CABG) with advancing age having been shown to have a significant association with its incidence. This study aims to assess whether off-pump coronary artery bypass (OPCAB) reduces the incidence of atrial fibrillation in elderly patients. METHODS A meta-analysis of all observational studies reporting a comparison between the two techniques in elderly patients (> 70 years) between 1999-2003 was performed. The primary outcome of interest was the incidence of postoperative atrial fibrillation. The quality of each study was evaluated by examining three items: patient selection, matching of the off-pump and cardiopulmonary bypass patient groups, and assessment of outcome. Meta-regression analysis was undertaken to see the effects of study size and quality on the calculated odds ratio. RESULTS Eight studies fulfilled our inclusion criteria, all of which were nonrandomized. In total the studies identified 3017 subjects, of which 764 had off-pump surgery (25%) and 2253 underwent cardiopulmonary bypass (75%). Meta-analysis showed that after off-pump surgery there was a significantly lower incidence of postoperative atrial fibrillation in these patients (odds ratio 0.70, 95% confidence interval [CI] 0.56-0.89). Meta-regression analysis including study characteristics did not show any associations affecting the calculated odds ratio of atrial fibrillation. CONCLUSIONS Our study demonstrates a reduced incidence of postoperative atrial fibrillation in an elderly population with off-pump as compared with cardiopulmonary bypass techniques. We appreciate, however, that our statistical analysis uses nonrandomized published data and that the results must be treated with caution. If this finding is confirmed by a large-scale randomized trial, it has significant implications on the operative strategy employed for this patient group.

Abstract
Several recent studies have highlighted the potential benefits of using off-pump coronary artery bypass (OPCAB) surgery, particularly in high-risk patients. The aim of this meta-analysis is to assess the effect of OPCAB on the incidence of stroke compared with coronary artery bypass grafting using cardiopulmonary bypass (CPB) in elderly patients. We performed a meta-analysis of all observational studies, published in MEDLINE between 1999 and 2002 and a comparison between the OPCAB and CPB techniques in elderly patients was performed with the outcome of interest being the incidence of stroke. Elderly patients were defined as those aged 70 years or older. Nine studies are included in the meta-analysis. The total number of subjects included was 4,475 patients, of which, 1,253 underwent OPCAB (28%) and 3,222 (72%) underwent CPB. The meta-analysis showed that the OPCAB technique was associated with significantly lower incidence of stroke in elderly patients compared with the CPB technique (1% vs 3%), with an odds ratio of 0.38% to 95% (CI, 0.22 to 0.65). We did not identify any significant heterogeneity and funnel plot asymmetry between the studies included in the meta-analysis. Meta-regression analysis including variables predicting stroke, mortality, and study characteristics did not show any associations affecting the calculated odds ratio of stroke. Despite the fact that this is a meta-analysis of observational studies and adjustment for differences in baseline risk factors between OPCAB and CPB patients was not possible, we believe that this study suggests that the OPCAB technique might be associated with reduced incidence of stroke in the elderly patients undergoing coronary artery bypass grafting.

Abstract
BACKGROUND To evaluate hospital mortality and morbidity after myocardial revascularization in a prospective and multicenter study, comparing on-pump versus off-pump in a special subset of patients with lesions in the left descending artery, alone or associated with the right coronary artery. METHODS A multicenter prospective randomized study was performed. One hundred and sixty selected low-risk patients were enrolled; 80 patients were operated on-pump (coronary artery bypass grafting [CABG], group I) and 80 patients were operated off-pump (off-pump coronary artery bypass [OPCAB], group II). One hundred and five were male and ages ranged from 39 to 70 years old; mean 58.81 +/- 9.31 and median 59. Preoperative clinical characteristics were similar in both groups; only previous myocardial infarction was higher in the OPCAB group. Patients with severe left ventricular dysfunction (FE </= 35%), renal failure and lesions of the circumflex artery and its branches were excluded, as well as patients with significant comorbidities that were inappropriate for randomization because we selected them for OPCAB procedures. RESULTS Hospital mortality was 2.5%, three patients (3.7%) in group I (on-pump) and one patient (1.2%) in group II (off-pump) (ns). The number of grafts per patients in group I was 1.81 +/- 0.6, and 1.77 +/- 0.68 in group II (p = 0.833). There was no difference in the total operation time 205.10 +/- 54.30 minutes in group I and 189.50 +/- 55.44 in group II (ns). Six patients (7.5%) had myocardial infarction in group I and three (3.7%) in group II (ns). Bleeding in the postoperative period was 680.50 +/- 434.1 mL in the on-pump group and 678.6 +/- 357.0 mL in the off-pump group (ns). Three patients (3.7%) presented transient neurologic dysfunction in group I and six patients (7.5%) in group II (ns). Intensive care stay was 2.4 +/- 1.0 days in the CABG and 2.3 +/- 0.98 days in the OPCAB group (ns). CONCLUSIONS We did not find any statistical difference in hospital mortality and morbidity using on-pump or off-pump techniques for low-risk patients.

Abstract
BACKGROUND Comparative publications on beating-heart off-pump coronary artery bypass grafting (OPCAB) surgery versus conventional coronary artery bypass grafting (CCAB) surgery frequently do not offer conclusive information because of investigator bias. METHODS Trying to eliminate this problem, a propensity score analysis of the data of all CCAB patients (n = 517) and OPCAB patients (n = 133) operated on by the same surgeons during the same time period (1998 to 2001) was applied. After matching patients with similar propensity score values, 97 CCAB patients and 72 OPCAB patients entered the final analysis. RESULTS Early results were similar in both groups: the 30-day mortality reached 1.4% in the CCAB group and 2.8% in the OPCAB group; strokes did not happen. Perioperative myocardial infarctions occurred in 4.1% of the CCAB patients and 4.3% of the OPCAB patients. Drainage blood loss in the first 24 hours after surgery (830 +/- 687 mL, CCAB group; and 909 +/- 678 mL, OPCAB group) was similar (p = 0.06) in both groups. Medium term results (freedom from percutaneous transluminal coronary angioplasty or reoperation, freedom from myocardial infarction, freedom from stroke, and the quality of life) also were not significantly different between the off-pump and on-pump groups after a mean follow-up of 27 +/- 11 months. CONCLUSIONS Our results suggest that elective-surgery patients with coronary artery disease can be operated on either on-pump or off-pump with the same early and late mortality and morbidity.

Abstract
BACKGROUND The female gender is an independent predictor of adverse outcome after conventional coronary artery bypass grafting using cardiopulmonary bypass. The aim of this study is to assess the effect of the female gender on the outcome after off-pump coronary artery bypass (OPCAB) surgery. METHODS This study is a retrospective review of 413 consecutive patients (181 women and 232 men) who underwent OPCAB between January 1999 and May 2001. Adverse outcomes were divided into minor adverse outcomes (MINAO), major adverse outcomes (MAJAO), and prolonged length of stay (PLOS) more than 7 days. MINAO included atrial fibrillation, respiratory complications except adult respiratory distress syndrome, and any wound infection except mediastinitis. MAJAO included stroke, myocardial infarction, renal failure, adult respiratory distress syndrome, mediastinitis, low cardiac output, mechanical ventilation more than 24 hours, intensive therapy unit stay more than 24 hours, gastrointestinal complications, cardiorespiratory arrest, and mortality within 30 days. Preoperative and intraoperative variables were evaluated as predictors of MINAO, MAJAO, and PLOS by univariate and multivariate analyses. RESULTS The groups were matched for age and Parsonnet score-predicted mortality. However, the women had a higher incidence of chronic obstructive airway disease (p = 0.04), diabetes (p = 0.01), obesity (p = 0.000), peripheral vascular disease (p = 0.000), hypertension (p = 0.000), unstable angina (p = 0.005), history of previous failed nonsurgical intervention (p = 0.02), and nonelective operation (p = 0.000). There were a fewer number of grafts performed in the female group (2.8 vs 3.4, p = 0.000), with the circumflex territory being revascularised less frequently (p = 0.001). Univariate analysis identified the female gender to be a predictor of only MINAO (p = 0.001) and PLOS (p = 0.000). However, with multivariate analysis, female gender was not found to be an independent predictor of MINAO, MAJAO, or PLOS. CONCLUSIONS In OPCAB, the female gender is not an independent predictor of MINAO, MAJAO, or PLOS.

Abstract
BACKGROUND We compared our experience of minimal tissue dissection and target vessel revascularization without cardiopulmonary bypass (CPB) with the standard procedure of total dissection of the heart and complete revascularization with CPB in patients who had elective reoperative coronary artery bypass grafting (redo-CABG). METHODS We analyzed recurrence of angina and clinical outcome in 118 patients who had elective redo-CABG between January 1995 and April 2002. Seventy-four patients had redo-CABG with CPB, and 44 patients had redo-CABG without CPB. RESULTS Perioperative outcome was comparable with regard to morbidity and mortality rates. At follow-up, the mean Canadian Cardiovascular Society score was 1.3 +/- 0.6 in patients who had redo-CABG with CPB and 1.7 +/- 0.8 in patients who had redo-CABG without CPB (p = 0.02). At follow-up, patients who had redo-CABG without CPB had a higher rate of recurrence of angina (log rank = 0.001) and higher use of nitrates (p = 0.015). Target vessel revascularization was an independent predictor of recurrence of angina in younger patients (< 75 years; p = 0.012) but not in the elderly (> or = 75 years; p = 0.142). CONCLUSIONS In elective redo-CABG patients, minimal tissue dissection and target vessel revascularization without cardiopulmonary bypass did not add significant benefit with regard to perioperative morbidity and mortality. The unsatisfactory relief of symptoms does not seem to justify target vessel revascularization by a less invasive approach. Therefore, this technique should be offered exclusively to patients at high risk with complete revascularization using CPB, such as the elderly.

Abstract
BACKGROUND Increase in life expectancy is causing an increase of surgical myocardial revascularization procedures in the elderly. We evaluate the evolution of this type of interventions in people older than 75 years, taking into account the risk factors, results and survival. PATIENTS AND METHOD Between July 1988 and May 2001, 237 isolated or combined myocardial revascularization procedures were carried out in patients older than 75 years (Group I), while 1177 were performed in younger patients (Group II). We retrospectively analyzed the mortality risk factors, surgical procedures, postoperative complications and survival in Group I patients. RESULTS Preoperatively, Group I patients showed a more frequent left ventricular dysfunction, left main coronary stenosis, emergency surgery and combined procedures, while Group II patients displayed more common preoperative myocardial infarction and dyslipemia. Mortality in Group I was 20.7% vs 9.09% in Group II. Mortality was higher for mixed procedures (27.1%) than for isolated myocardial revascularization (13.8%). Postoperative complications were present in 48.5% patients. Significant preoperative risk factors of mortality in Group I were: female sex, high-risk ergometry, III-IV NYHA functional class, and atrial arrhythmia. The preoperative NYHA functional class was also a morbidity risk factor. Survival at 1, 3 and 5 years was present in 98.4%, 92.1% and 81% patients, respectively, NYHA functional class I-II being present in 94.18% patients. CONCLUSIONS Myocardial revascularization surgery in people older than 75 years leads to an increase of morbimortality. Anyway, long-term survivors' quality of life makes us think of surgery as a valid treatment alternative.

Abstract
A retrospective analysis was performed to determine the early outcome of cardiac and thoracic aortic surgery in patients over 80 years old. Between 1994 and 2000, 41 octogenarians (mean age, 82.6 +/- 2.5 years) underwent coronary artery bypass grafting (25), valve surgery (8), thoracic aortic aneurysm repair (7), or combined valve and bypass surgery (1). Overall hospital mortality was 9.8%. Mortality rates for specific procedures were 12% for coronary bypass, 0% for valve surgery, and 14% for thoracic aortic aneurysm repair. Major postoperative complications affected 27% of patients and included severe low cardiac output, respiratory failure, and acute renal failure, with a low incidence of perioperative stroke (2.4%). Cardiac and thoracic aortic operations can be performed with acceptable mortality and morbidity when appropriately applied in selected octogenarians.
