Abstract
This report discusses the case of a 57-year-old woman with a history of breast cancer and gastric cancer, germline CDH1 gene mutation, who presented to the hospital with syncope. Diagnostic workup revealed a mass in the right ventricular outflow tract. Transcatheter biopsy suggested papillary fibroelastoma, which was confirmed with surgical pathology. This case highlights an atypical presentation of papillary fibroelastoma, which was successfully managed through a multidisciplinary approach.
