Abstract
Early and long-term outcomes in elderly patients who underwent isolated aortic valve replacement (iAVR) are well defined. Conflicting data exist in elderly patients who underwent AVR plus coronary artery bypass grafting (CABG). We sought to evaluate the early and long-term outcomes of combined AVR + CABG in patients older than 75 years of age. From June 1999 to June 2018, 402 patients ≥ 75 years who underwent iAVR (n = 200; 49.7%) or combined AVR plus CABG (n = 202; 50.3%) were retrospectively analysed. AVR + CABG patients were older than iAVR patients (78.5 ± 2.5 vs 77.6 ± 2.8 years; p < 0.0001), with greater co-morbidities and more urgent/emergency surgery. 30-day mortality was 6.5% in the AVR + CABG and 4.5% in the iAVR group (p = 0.38). Multivariate analysis identified EuroSCORE II [odd ratio (OR) 1.13] postoperative stroke (OR 12.53), postoperative low cardiac output syndrome (OR 8.72) and postoperative mechanical ventilation > 48 h (OR 8.92) as independent predictors of 30-day mortality; preoperative cerebrovascular events (OR 3.43), creatinine (OR 7.27) and extracorporeal circulation time (OR 1.01) were independent predictors of in-hospital major adverse cardiovascular and cerebral events (MACCE). Treatment was not an independent predictor of 30-day mortality and in-hospital MACCE. Survival at 1, 5 and 10 years was 94.7 ± 1.6%, 72.6 ± 3.6% and 31.7 ± 4.8% for iAVR patients and 89.1 ± 2.3%, 73.9 ± 3.5% and 37.2 ± 4.8% for AVR + CABG subjects (p = 0.99). Using adjusted Cox regression model, creatinine [hazard ration (HR) 1.50; p = 0.018], COPD (HR 1.97; p = 0.003) and NYHA class (HR 1.39; p < 0.0001) were independent predictors of late mortality; the combined AVR + CABG was not associated with increased risk of late mortality (HR 0.83; p = 0.30). In patients aged ≥ 75 years, combined AVR + CABG was not associated with increased 30-day mortality, in-hospital MACCE and long-term mortality. Surgical revascularization can be safely undertaken at the time of AVR in elderly patients.
