Background: Increased experience and improvements in technology seem to have encouraged the use of percutaneous interventions for left main coronary artery (LMCA) occlusions. There is no consensus, however, and the data are inadequate on whether surgery or percutaneous procedures should be the intervention of choice for critical occlusions.Methods: From January 2002 to December 2006, 108 patients with unprotected LMCA stenosis >80% were treated at our center. Eighty-three patients (77%) underwent bypass grafting and 20 (18%) underwent percutaneous intervention for the purpose of myocardial revascularization. We analyzed parameters demonstrated as risk factors for myocardial revascularization and their predicted effects on outcome.Results: Five patients (5%) died following emergency cardiopulmonary resuscitation before any intervention was performed. The early survival rate was 84.1% in the coronary bypass group and 63% in the percutaneous intervention group. The mean (SD) survival time was 55.7 2.6 months in the bypass group and 7.6 1.3 months in the percutaneous group. The late-survival rate was also significantly higher in the bypass group. The mean late-survival time was 44.5 3.6 months in the bypass group and 2.3 0.8 months in the percutaneous group.Conclusion: Although emergency percutaneous interventions are lifesaving in some cases, these results clearly demonstrate that coronary bypass grafting should be the intervention of choice for myocardial revascularization in patients with critical LMCA occlusion.

Abstract Background The benefit of arterial revascularization in coronary surgery remains controversial. The incremental value of additional grafts to the left internal thoracic artery (ITA) has been mainly assessed according to the number of arterial grafts, possibly limiting the detection of its actual impact. We analyzed the influence of the number of distal arterial anastomoses (DAA) performed on late mortality in patients having received from one to three arterial grafts. Methods Retrospective review of 3685 primary isolated coronary artery bypass grafting (CABG) performed from 1989 to 2014 was conducted with a 13-year mean follow-up. One arterial graft (SITA) was used in 969 patients, two arterial grafts, ITA or gastroepiploic artery (GEA), in 1883 patients (BITA: 1644; SITA+GEA: 239), and three arterial grafts in 833 patients (BITA+GEA). Totally, 795 patients (22%) received one DAA, 1142 patients (31%) two, 1337 patients (36%) three, and 411 patients (11%) four or more. A sub-group analysis was done in the 2104 patients with 3-vessel disease who received at least 2 arterial grafts. Results In this series the early mortality was 1.6% and it was not influenced by the surgical technique. Late mortality was significantly influenced by age, gender, heart failure, LV ejection fraction, diabetes status, complete revascularization, number of arterial grafts, number of DAA, both ITA, sequential ITA graft, GEA graft. In multivariable analysis with Cox regression model, the number of DAA was the only technical significant independent prognosis factor of late survival (p < 0.0001), predominant over both ITA, complete revascularization and number of arterial grafts. The impact of the number of DAA on survival was found discriminant from 1 to 3; after 3 there was no more additional effect. In 3-vessel disease patients who received at least 2 arterial grafts, the number of DAA remained a significant independent prognosis factor of late survival (p < 0.0001). Conclusions The number of distal arterial anastomoses is an independent predictor of long-term survival, predominant over the number of arterial grafts and the completeness of the revascularization; higher the number, better the late survival. It is a strong support of the extensive use of arterial grafting in CABG.

Late Survival

Background —The optimal management of aortic valve disease in patients >80 years old depends on functional outcome as well as operative risks and late survival. Methods and Results —We retrospectively identified 133 patients (62 men, 71 women) aged 80 to 91 years (mean 84±3 years) who underwent aortic valve replacement alone or in combination with another procedure between January 1, 1993, and April 31, 1998. Demographics included hypertension 68%, diabetes mellitus 17%, and history of stroke 11%. Operative (30 day) mortality rate was 11%. Urgent or emergent surgery, aortic insufficiency, and perioperative stroke or renal dysfunction were risk factors for operative death by multivariable analysis. Intensive care unit and total hospital length of stay were prolonged at 6.2 and 14.7 days, respectively. Late follow-up between July 1, 1998, and November 1, 1999, was 98% complete. Actuarial survival at 1 and 5 years was 80% and 55%, respectively. Predictors of late mortality were preoperative or perioperative stroke, chronic obstructive pulmonary disease, aortic stenosis, and postoperative renal dysfunction. The mean New York Heart Association functional class for 65 long-term survivors improved from 3.1 to 1.7. Quality of life assessed with the Medical Outcomes Study Short Form-36 was comparable to that predicted for the general population >75 years old. Conclusions —Functional outcome after aortic valve replacement in patients >80 years old is excellent, the operative risk is acceptable, and the late survival rate is good. Surgery should not be withheld from the elderly on the basis of age alone.
