Is Off-Pump CABG Really Inferior to On-Pump Strategies for Long-Term Survival?

Preoperative Factors Associated With Postoperative Requirements of Renal Replacement Therapy Following Cardiac Surgery

“…Note, however, that we routinely perform off-pump coronary bypass surgery on most of our patients, and a requirement for CPB is an extreme exception. 21 Berg et al 4 recently reported that the risk for acute renal failure can be accurately predicted using preoperative variables. They demonstrated that the use of intraoperative variables slightly improved the model but did not seem to outweigh the advantages of a preoperative model.…”

“…First, our observations were based on a single-center, retrospective analysis, although our institution has performed the greatest number of open-heart surgical procedures in Japan, >600 cases per year excluding emergency procedures. 21 Another limitation was that we did not include measurements of high-sensitivity CRP, which is a more sensitive and stronger inflammatory biomarker than conventional CRP. The greatest limitation of the present analysis was that we did not include perioperative information, such as amounts of transfused blood volume or pump durations, apart from the CPB requirements.…”

Long-Term Patency Rate of Radial Artery Conduits in Chinese Patients Undergoing Off-Pump Coronary Artery Bypass Grafting

“…The RA patency after off-pump CABG did not trans-late into the RA patency following on-pump CABG. Offpump coronary bypass surgery, compared to on-pump, may have an adverse effect on anastomotic patency, 26) resulting in potentially inferior RA patency after off-pump CABG. However, we did not have enough data to identify the RA patency after on-pump CABG.…”

Early Postoperative Outcome of Off-Pump Coronary Artery Bypass Grafting: A Report from the Highest-Volume Center in Japan

“…6) Especially in Japan, surgeons have become proficient in OPCAB techniques in the past 10 years. Therefore, a proportion of OPCAB among total CABG cases in Japan has reached more than 60%, 4,7,8) which is extremely higher than that in the US (17%) (Fig. 1).…”
