Representative cases. A 63-year-old asymptomatic woman with a BAC score of 5 (yellow arrow heads) on screening mammography (A) demonstrated calcified plaque without significant stenosis (percent diameter stenosis, 10–20%) at the proximal LAD and mixed plaque (percent diameter stenosis, 10–20%) at the mid LAD (yellow arrow). (B) Three years later, she was referred to the emergency department with chest pain and underwent CCTA, which demonstrated progression of the mid LAD lesion (percent diameter stenosis, 90%; yellow arrow). (C) Invasive angiography also demonstrated the tight stenosis of the mid LAD (percent diameter stenosis, 90%) and percutaneous coronary intervention was performed. A 51-year-old asymptomatic woman without evidence of BAC (red arrow heads) on screening mammography (D) demonstrated calcified plaque (percent diameter stenosis, 30%) at the mid LAD (red arrow). (E) Five years later, she visited the outpatient clinic due to epigastric pain and underwent CCTA, which demonstrated no change in the mid LAD lesion (red arrow). (F) BAC, breast arterial calcification; CCTA, coronary computed tomographic angiography; LAD, left anterior descending artery.
