ObjectivesThe present study sought to compare postoperative bleeding and renal function in patients with multivessel coronary artery disease undergoing simultaneous hybrid coronary revascularization (HCR) and minimally invasive direct off-pump coronary artery bypass grafting (MIDCABG).MethodsThe study retrospectively collected the data of 594 consecutive patients who underwent simultaneous HCR and 351 patients who underwent MIDCABG with planned staged HCR (MIDCABG first, then elective percutaneous coronary intervention) in Fuwai Hospital from June 2007 to December 2020. A total of 317 pairs of patients who were matched in a 1:1 ratio with propensity score matching were enrolled in this study. Bleeding and changes in renal function were compared between the 2 groups.ResultsCompared with patients who underwent MIDCABG, patients who underwent simultaneous HCR had significantly greater chest tube drainage on the day of the operation (492.7 ± 282.4 mL vs 441.0 ± 261.9 mL; P = .023), but no significant difference was detected in the total amount during the postoperative period (788.8 ± 458.9 mL vs 753.3 ± 409.8 mL; P = .74). The differences in re-exploration for bleeding (0.3% vs 1.6%; P = .13), blood transfusion (18.9% vs 16.4%; P = .13), acute kidney injury (23.3% vs 18.6%; P = .53), and in-hospital major adverse cardiovascular and cerebrovascular events (including all-cause death, myocardial infarction, stroke, and repeated revascularization) (2.5% vs 1.9%; P = .67) between the 2 groups did not reach statistical significance.ConclusionsCompared with MIDCABG, simultaneous HCR (MIDCABG first, instant percutaneous coronary intervention) did not increase postoperative bleeding or the incidence of acute kidney injury.Copyright © 2022 The American Association for Thoracic Surgery.
