Background: Amyloidosis is an important infiltrative cardiac disease and recognition of imaging findings is crucial. This study was performed to determine the delayed enhancement pattern in patients with cardiac amyloidosis in Shahid Rajaei Heart Center. Materials and Methods: In this case series study, 30 patients with amyloidosis (confirmed by Subcutaneous Abdominal Fat biopsy) in ShahidRajaeiHeartCenter in Tehran, Iran in 2016 and 2017 were enrolled and the presence of delayed enhancement patterns of cardiac amyloidosis were determined in them. Results: Results showed that 46.7% had no enhancement, 40% had subendocardial, 3.3% subepicardial, 3.3% transmural, and 6.7% patchy pattern, respectively. The subendocardial pattern was significantly higher in amyloidosis cases (P=0.030). Conclusion: Overall, it may be concluded that subendocardial enhancement pattern is more common in patients with amyloidosis and it may be used as a diagnostic index.
