Abstract

OBJECTIVE:

The aim of this study was to summarize the immediate outcome after aortic valve replacement (AVR) with or without coronary artery bypass grafting (CABG).

DESIGN:

Systematic review and meta-analysis.

SETTING:

University hospitals.

PARTICIPANTS:

Participants were 683,286 patients who underwent AVR with or without CABG. Patients undergoing other major cardiac procedures were excluded from this analysis.

INTERVENTIONS:

AVR with or without CABG.

MEASUREMENTS AND MAIN RESULTS:

Operative mortality after AVR with or without concomitant CABG was 4.3%, stroke 2.1%, pacemaker implantation 5.9%, and dialysis 2.2%. After isolated AVR, operative mortality was 3.3%, stroke 1.7%, pacemaker implantation 3.3%, and dialysis 1.6%. Mortality was increased among very elderly (<60 years: 3.3%, 60-69 years: 2.7%, 70-79 years: 3.8%,≥80 years: 6.1%, p<0.001). Prevalence of minimally invasive AVR (mini-AVR) was associated with significantly lower operative mortality (p = 0.039, 46 studies). Mini-AVR only tended toward lower mortality when included in meta-regression analysis as a dichotomous variable (mini-AVR 4,367 patients: 2.3%, 95% CI 1.8-2.9% v full sternotomy 11,076 patients: 3.5%, 95% CI 28-4.1%, p = 0.088). Operative mortality after AVR plus CABG was 5.5% (versus isolated AVR: p<0.001), stroke 3.0%, pacemaker implantation 3.9%, and dialysis 5.6%. Mortality was high in all age strata, particularly among very elderly (mean age<70 years: 4.8%, mean age 70-79 years: 4.7%; mean age≥80 years: 8.4%, p = 0.002).

CONCLUSIONS:

Isolated AVR is associated with low mortality and morbidity. Coronary artery disease requiring concomitant CABG increases the operative mortality. Patients requiring AVR and CABG should be the main target of less-invasive treatment strategies.
