Figure 10: A 57-year-old female is a known case of systemic hypertension, type II diabetes mellitus, and dyslipidemia. She suffered acute posterior wall and RV myocardial infarction and underwent primary percutaneous transluminal coronary angioplasty to the right coronary artery. Echocardiography showed ostium secundum atrial septal defect with left-to-right shunt and RA free wall mass. (a) 4C cine systolic image showing thickening (blue arrow) along the lateral wall of the RA. (b) Corresponding 4C LGE shows no appreciable enhancement (blue arrow). Final diagnosis: The typical location and absent enhancement are consistent with crista terminalis. 4C: Four-chamber, LGE: Late gadolinium enhancement, RA: Right atrium, RV: Right ventricle
