# 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.

## Key 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.
