“…14 Anaortic OPCAB is a well-established technique which in dedicated high-volume practices has been shown to lower risk of 30-day mortality (odds ratio 0.42, p < .001), early complications, and length of hospital stay while providing equivalent longterm outcomes compared with standard CABG decades after surgery. 22,26,[28][29][30][31] Furthermore, OPCAB reduces operative blood loss and thus need for transfusion of blood products which are associated with adverse outcomes. 32 Furthermore, OPCAB has been shown to benefit elderly patients, especially those with high calcific load, diabetes, and COPD, reducing their risk of death, stroke, and MI.…”
