Incidental Finding of a Superdominant Left Anterior Descending Artery in an 80-Year-Old Woman: Case Report and Literature Review.

We report a case of an 80-year-old woman who presented to the hospital with sudden-onset palpitation, where, during an out-patient clinic follow-up, we discovered a rare coronary artery finding on radiological imaging, and to the best of my research, the first reported case in the United Arab Emirates. We discovered during a CT angiography (CTA) scan a Type IV left anterior descending (LAD) artery, where the artery continues around the apex of the heart and ascends within the posterior interventricular groove as the posterior dominant artery. Since the encounter at the emergency room, our patient, who is dependent on her family members for most activities of daily living, has not experienced another onset of palpitation. She regularly visits her doctor, is compliant with her medications, and maintains a healthy lifestyle, following up with her cardiologist on a monthly basis.
