Material and Methods
This study used a matched cohort design to examine short-term and midterm outcomes between patients undergoing competing surgical approaches: OPCAB and hybrid revascularization. Hybrid procedures were defined as those in which a minimally invasive LIMA-LAD bypass was performed in combination with PCI to at least 1 major non-LAD coronary artery (right coronary artery or circumflex artery, or both). In all, 147 hybrid cases were identified querying the Emory University institutional Society of
Results
A total of 147 patients underwent hybrid coronary revascularization combining a minimally invasive LIMA-LAD bypass with PCI of non-LAD coronary vessels. These patients were matched 4:1 with contemporaneous OPCAB patients based on 8 preoperative variables. Patients were well matched with no significant differences with the exception of female gender, with more female patients in the hybrid group (20.2% standardized difference) (Table 1). According to unmatched variables there were no significant
Comment
To our knowledge, the current study represents 1 of the largest comparisons of HCR to conventional CABG. In this study, patients undergoing HCR had similar in-hospital mortality and midterm survival rates as those undergoing OPCAB. With the exception of a lower incidence of transfusion in the HCR group, other in-hospital outcomes were similar between groups. The incidence of repeated revascularization was higher in the HCR group compared with the OPCAB group. In smaller studies, both Kon and

2022, IJC Heart and VasculatureCitation Excerpt :PCI techniques have improved over the last years moving from BMS to third-generation DES. Secondary cardiovascular management changed with the introduction of more effective anti-thrombotic medications for better stent protection [44–47]. In the past two decades, the adoption of MIDCAB for isolated proximal LAD lesions or in combination with PCI (hybrid coronary revascularization) increased worldwide.
