Key result
Coexisting type II double LAD and partial ARCAPA potentially limit ischemic burden in an asymptomatic patient.
Why the study?
Knowledge of the coexistence of rare coronary artery anomalies assessed by CCTA is essential for accurate diagnosis and management.
Highlights the rare coexistence of partial ARCAPA and dual LAD, emphasizing the role of CCTA in diagnosing complex congenital coronary anomalies.
CCTA supports diagnosis of complex congenital coronary anomalies; hypothesis-generating for protective anatomic variants limiting ischemic burden.
This case report highlights the coexistence of two rare coronary artery anomalies assessed by computed coronary tomography angiography (CCTA). We present the case of a 51-year-old hypertensive patient with a type II double left anterior descending artery (LAD) and an anomalous infundibular branch originating from the pulmonary artery (partial ARCAPA). This association may have contributed to a limited ischemic burden, explaining the patient’s asymptomatic state. Knowledge of these rare coronary anatomies is essential for accurate diagnosis and management.
