Clinical Impact of Preoperative Symptoms of Aortic Stenosis on Prognosis After Transcatheter Aortic Valve Replacement

Abstract

Study Population and Data CollectionWe retrospectively enrolled 369 consecutive patients with native severe aortic valve stenosis who underwent TAVR at Gunma Prefectural Cardiovascular Center from 2014 to 2021.
