The rare coexistence of a type II double left anterior descending artery and partial ARCAPA potentially limited ischemic burden in an asymptomatic 51-year-old patient.
Highlights the rare coexistence of partial ARCAPA and dual LAD, emphasizing the role of CCTA in diagnosing complex congenital coronary anomalies.
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.
