Abstract 4283: Outcomes of Patients Undergoing Concomitant Aortic and Mitral Valve Surgery in Northern New England

TL;DRAbstract

Background : During the past 20 years (yrs), there has been a steady increase in concomitant aortic(AV) and mitral valve(MV) surgery in northern New England (NNE). We examined the in-hospital and long-term mortality for these patients by procedure, patient age and sex. Methods : This is a prospective, regional, cohort study of 1057 patients undergoing concomitant AV and MV surgery in NNE from 1989 through 2007. Long-term survival was obtained by linking our registry data to the Social Security Administration Death Master File. Kaplan-Meier and log-rank tests were performed. Results : Patient characteristics: age <70 yrs (45.1%), 70–79 yrs (41.0%), and ≥ 80 yrs (13.9%); female sex (44.1%); associated CABG (46.9%); diabetes (19.5%); CHF (60.7%); PVD (17.7%); non dialysis renal failure (RF) (5.3%); dialysis dependant RF (2.4%). In-hospital mortality was 15.4% (11.0% for patients <70 yrs, 18.0% for 70–79 year olds, and 24% for those ≥80). The median period of follow-up was 3.5 yrs. O
