ABSTRACT
BACKGROUND:
Coronary artery bypass grafting (CABG) can be performed through a variety of approaches. Minimally-invasive CABG (MICABG) may reduce perioperative morbidity. Previous results demonstrate improved perioperative outcomes; however, adoption has been limited.METHODS:
The Society of Thoracic Surgeons (STS) database and electronic medical record at a single institution were reviewed for isolated left internal mammary to left anterior descending artery (LIMA-LAD) bypass procedures performed between 2011 and 2018. Patients were grouped on the basis of operative approach, comparing sternotomy to non-sternotomy (minimally-invasive). Patient characteristics, perioperative variables, and short- and long-term outcomes were compared. Primary outcomes included mortality and major adverse cardiac events (MACE). Secondary outcomes were morbidity.RESULTS:
A total of 42 MICABG and 54 conventional LIMA-LAD procedures were performed with 95.2% of MICABG procedures performed by two surgeons. MICABG were more often elective (83.3 vs 38.9%, P < .001). STS risk scores predicted equitable mortality and morbidity for MICABG dependent on operative indication. MICABG was associated with fewer pulmonary complications (0.0 vs 11.1%, P = .033), in-hospital events (11.9 vs 37.0%, P = .005), and shorter intensive care unit (34.1 vs 66.0 hours, P = .022) and total length of stay (3.7 vs 6.5 days, P = .002). There were no observed strokes, myocardial infarctions, or reoperations. MICABG patients demonstrated reduced thirty-day mortality (0.0 vs 10.9%, P = .036) and improved Kaplan-Meier 5-year (95.2 vs 77.9%, P = .016) and MACE-free survival (89.2 vs 63.9%, P = .010).CONCLUSIONS:
Minimally-invasive LIMA-LAD CABG demonstrates improved early postoperative morbidity and a long-term mortality benefit. In select patients, minimally-invasive approaches to single-vessel grafting may be beneficial when performed by experienced surgeons in the elective setting.
