# A coronary coronary-to-coronary fistula around the main pulmonary artery

## TL;DR

This paper describes a rare coronary-to-coronary fistula around the pulmonary artery and discusses its clinical implications.

## Contribution

The study presents a unique case of a coronary-to-coronary fistula involving the main pulmonary artery.

## Key findings

- Coronary-to-coronary fistulas are rare and often detected incidentally.
- Management depends on symptoms, with asymptomatic cases typically requiring observation.

## Abstract

Coronary-to-coronary fistulas are rare anomalies, often detected incidentally. These fistulas may involve complex vascular connections around major cardiac structures, such as the pulmonary artery. Functional assessments help determine clinical significance, with management typically involving observation for asymptomatic patients, while symptomatic cases may require intervention to prevent complications.
