Ejection fraction by cardiovascular magnetic resonance predicts adverse outcomes post aortic valve replacement

This free journal suppl. entitled: British Cardiovascular Society Annual Conference 2014 02-04 June 2014, Manchester Central, ManchesterIntroduction Predicting prognosis following aortic valve replacement (AVR) in patients with aortic stenosis (AS) remains challenging. Current guidelines recommend that surgery should be offered when ejection fraction (EF) is 70%; n = 28). A median 5.0 ± 1.8 years follow-up was completed using the National Strategic Tracing Scheme and hospital notes.Results Univariate analysis of all cause mortality using the Kaplan-Meier estimator demonstrated significantly higher mortality in patients with Group 1 (EF 70%; .03).There was no statistical difference between group 2 (EF of 50–70%) and the remaining 2 groups.Kaplan-Meier survival curve of all cause mortality in Group 1 (EF 70%)Conclusion Pre-operative EF is a significant predictor of mortality following AVR. Patients with EF 70% have the best prognosis. We aim to incease the sample size to determine whether a progressive decrease in EF per se even when above 50% should initiate consideration for AVR.link_to_OA_fulltex
