Background and aim of the study: The study aim was to determine if the ‘prophylactic’ replacement of the aortic valve to treat moderate aortic valve stenosis (AS) in octogenarians undergoing cardiac surgery for coronary disease can influence outcome, and is also justified.
Methods: In a retrospective analysis of octogenarians operated on at the authors’ center between 1998 and 2012, the patients were allocated to: Group I, isolated coronary artery bypass graft surgery (CABG; n = 159); Group II, combined CABG and aortic valve replacement (AVR) with the primary indication for surgery being severe AS (n = 156); and Group III, combined AVR +CABG with coronary disease being the primary indication and concomitant ‘prophylactic’ AVR (n = 34).
Results: The hospital mortality for octogenarians undergoing CABG+AVR was 8% compared to 2% for isolated CABG (p =0.02). Survival at one year was higher in the isolated CABG group (94%) than in the CABG+AVR group (86%) (p = 0.01), but was no different at five years. Mortality according to AVR indication was similar
(Group II 8% versus Group III 9%), as was one- and five-year survival. Group III had ahigher preoperative co-morbid risk profile, including logistic EuroSCORE 21.7% versus 18% in Group II (p = 0.05), more recent myocardial infarctions, previous percutaneous interventions, peripheral vascular disease, and poor left ventricular function. Long-term symptomatic relief was excellent in Group III. Patients whose predominant disease profile was ischemic (Groups I and III) had a higher long-term risk of recurrent angina and stroke.
Conclusion: In-hospital mortality is higher for octogenarians undergoing CABG+AVR compared to those undergoing isolated CABG. In the present study, a ‘prophylactic’ AVR was justified in patients with moderate AS, and their increased mortality (versus isolated CABG) was congruent with a higher preoperative co-morbid risk profile. Excellent long term symptom-free survival further justifies ‘prophylactic’ AVR in octogenarians undergoing CABG with coexistent moderate AS.
