SEGUEL, Enrique et al. Off Pump Coronary Artery Surgery in patients with Three Vessel and / or Main Left disease: long term results. Rev Chil Cardiol [online]. 2014, vol.33, n.2, pp.101-108. ISSN 0718-8560.

Aim: To present early and long term results of Off Pump Coronary artery surgery in patients with three vessel or Main Left Disease. Methods and Results: 100 patients, mean age 61,3 ± 7,9 years, 81% males, with three vessel or main left disease were submitted to off-pump coronary artery bypass between June 2005 and December 2008. Twenty patients had main left disease. Left ventricular ejection fraction was <30% in 6 patients, 30-50% in 32 and >50% in 62. Mean active and logistic Euro scores were 2.83 and 3.05, respectively. Patients were followed up to June 2013. All interventions were considered to have achieved complete revascularization. A mean of 3.07 bypasses were implanted. Five patients had to be converted to open heart surgery. 24 patients had post-operative complications (CVA in 3, AMI in 2, acute renal failure in 3 and mediastinitis in 1 patient. Operative mortality was 2% and 5 patients required reoperation. During a period of 72.3 months of follow-up (range 54-96) 14 patients died (5 from cardiovascular causes). There were 3 patients developing AMI, 5 suffered a CVA and 7 required re-revascularization. The overall results described were not different from those observed in similar patients undergoing open heart surgery at our institution. Conclusion: Off-Pump coronary artery bypass had no advantages over on pump surgery in patients with 3 vessel and/or main left disease at our institution.
