Abstract
The largest coronary artery aneurysm (CAA) previously documented in the literature is recorded to be 5 × 7 cm. With the aneurysm of this case's patient measuring 11.2 × 9.1 cm, it is significantly larger than what has previously been reported. Because of the lack of statistical data on CAAs, we propose that a large-scale study be undertaken to better understand presenting symptoms, size classification, and options for treatment of CAAs. Our case seeks to showcase the presentation and treatment of an exceptionally large CAA to begin to address the significant deficit in knowledge on this topic.
