Incidence and Risk Factors of Postoperative Dysphagia in Severe Aortic Stenosis

The aim of this study was to examine the incidence and risk factors of postoperative dysphagia in cases of severe aortic stenosis. The subjects were 192 severe aortic stenosis patients who underwent either surgical aortic valve replacement or transcatheter aortic valve implantation. We evaluated the frequency of postoperative dysphagia using the Food Intake Level Scale. Stepwise multivariate logistic regression analysis was performed to identify independent predictors of postoperative dysphagia. The only independent predictor of postoperative dysphagia was procedure type. The operative procedure type is a risk factor for postoperative dysphagia in cases of severe aortic stenosis.
