Aim. To comparably assess the perioperative risk factors that differentiate off-pump coronary artery bypass (OPCAB) grafting cases from those sustaining unplanned conversion to on-pump beating heart (ONCAB/BH) approach, in @entity1 with @entity1002 ( @entity1002 ) < 40%. Methods. Perioperative variables were retrospectively assessed in 216 @entity1 with @entity1002 < 40%, who underwent myocardial revascularization with OPCAB (n = 171) or ONCAB/BH (n = 45) approach. The study endpoints were operative mortality (30-day) and morbidity assessed by length of intensive care unit stay (LOS-ICU), using 2 days as cut-off point. Results. Poor @entity1002 , increased EuroSCORE II, acute presentation, @entity712 , @entity66 , perioperative @entity8 , clinical status deterioration upon admission and during ICU stay, acute @entity583 , and @entity998 supported by inotropes and/or balloon-pump counterpulsation were significantly related to ONCAB/BH group (P < 0.05). EuroSCORE II (P = 0.01) and @entity1002 (P = 0.03) were the most powerful discriminative predictors of intraoperative conversion to ONCAB/BH. Operative mortality was 2.9% in OPCAB and 6.6% in ONCAB/BH group (P = 0.224), while 23.4% @entity1 in OPCAB and 42.2% in ONCAB/BH approach had a LOS-ICU > 2 days (P = 0.007). Conclusions. @entity1 with @entity1002 < 40% undergoing ONCAB/BH are subjected to more preoperative comorbidities and implicated ICU stay than their OPCAB counterparts, which influences adversely short-term morbidity, while operative mortality remains unaffected.

A multidisciplinary approach to unplanned conversion from off-pump to on-pump beating heart coronary artery revascularization in XXXX with compromised left ventricular function.
