Rare Combination of Partial ARCAPA and Dual LAD: Insights into Complex Coronary Variants

TL;DR

A rare combination of two unusual heart artery structures was identified in a patient, offering insights into how such anomalies can coexist without causing symptoms.

Contribution

The paper presents a rare case of coexisting coronary artery anomalies that may explain an asymptomatic clinical presentation.

Findings

A patient had a type II double left anterior descending artery and a partial anomalous origin from the pulmonary artery.

The combination of these anomalies may have limited ischemic burden, resulting in an asymptomatic state.

The case emphasizes the importance of recognizing rare coronary anatomies for accurate diagnosis.

Abstract

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.
