Conversion and Safety in Off-Pump Coronary Artery Bypass: A System Failure That Needs Re-Emphasis

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

“…The most common reason for IOC is hypotension (32.3%), followed by either small size (26.9%) or intramuscular course of target vessels (22.6%), ischemia (17.7%), and arrhythmias (11.3%); less common reasons were hemorrhage, graft occlusion, calcified aorta, and need for concomitant surgery 96, 99…”

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

“…In contrast, emergency IOC is associated with significantly increased mortality risk 96. In an analysis based on the STS ACSD, Keeling et al97 reported observed to expected mortality of 1.4 for an elective IOC, 1.6 for emergency IOC for visualization reasons, and 2.7 for emergency IOC for hemodynamic instability.…”

Off-Pump or On-Pump Coronary-Artery Bypass Grafting

“…To the Editor: Diegeler et al (March 28 issue) 1 found no superiority of the off-pump CABG technique over the on-pump technique in an elderly population. The number of crossovers in this study highlights how frequently the initial surgical plan changes.…”

“…1 We report a case of progressive multifocal leukoencephalopathy (PML) in a patient with myelofibrosis after initiation of ruxolitinib therapy.…”
