# First-in-Human Percutaneous Use of a Cerebral Flow-Diverting Stent in a Large Coronary Aneurysm

## TL;DR

A cerebral flow-diverting stent was successfully used for the first time in a human to treat a large coronary aneurysm, resulting in symptom relief.

## Contribution

This is the first reported use of a cerebral flow-diverting stent to treat a coronary aneurysm in a human.

## Key findings

- The flow-diverting stent reduced flow to the aneurysm.
- The patient remained asymptomatic after the procedure.

## Abstract

A 58-year-old man presenting with angina was found to have a large coronary aneurysm on angiography. After coronary bypass and multiple ST-elevation myocardial infarctions over the following months, the decision was made to exclude the aneurysm with a flow-diverting stent, which reduced flow to the aneurysm and left the patient asymptomatic since the procedure. This is the first reported use of a cerebral flow-diverting stent for treatment of a coronary aneurysm.
