Conversion in Off-Pump coronary artery bypass grafting: an analysis of predictors and outcomes

Resultados inmediatos y a mediano plazo de la cirugía coronaria sin circulación extracorpórea: Experience in 220 patients

“…Como describen otros autores, la necesidad de convertir a cirugía con CEC, especialmente por inestabilidad eléctrica o hemodinámica se acompaña de una alta morbimortalidad 24,25 . En nuestra serie hubo 4 conversiones.…”

“…Las intervenciones se realizaron entre el 24 La fracción de eyección del ventrículo izquierdo fue < 30% en 9 (4,1%) pacientes, entre 30% y 50% en 57 (25,9%) y > 50% en 154 (70%).…”

Off‐Pump Coronary Artery Bypass Grafting: 30 Years of Debate

“…In the previously cited meta‐analysis, emergency conversion raised the OR of mortality to 6.99 (95% CI, 5.18–9.45) 98. In addition to the noted increased mortality, IOC is also associated with increased risk of almost all perioperative complications including myocardial ischemic injury, stroke, renal failure, and prolonged ventilation 97, 100, 101. Furthermore, IOC is associated with increased costs102 as well as hospital readmissions and infectious complications 103.…”

“…Elective IOC is usually well tolerated and associated with no increase in operative mortality 96, 99, 100…”

“…Keeling et al97 showed that older age, EF <35%, preoperative need for intra‐aortic balloon pump, increasing number of diseased native coronary vessels, history of congestive heart failure, and urgent status of surgery are all independent predictors of IOC. Other identified risk factors for IOC are left main coronary artery disease, intramyocardial course of coronary targets, reoperative procedures, and increasing number of coronary grafts constructed 99, 100, 105…”
