## TL;DR

This case report describes a rare but serious complication during a heart procedure and highlights the importance of timely treatment to avoid severe outcomes.

## Contribution

The paper presents a successful case of managing iatrogenic coronary dissection through early intervention and tailored treatment.

## Key findings

- Iatrogenic coronary dissection can occur during PCI and requires immediate recognition.
- Successful recanalization was achieved through individualized management and early intervention.
- Appropriate treatment strategies depend on the dissection's extent and location.

## Abstract

Catheter-induced coronary artery dissection is a rare and serious complication that may occur during coronary angiography or angioplasty procedures. Its timely recognition and appropriate management are critical to prevent severe consequences such as myocardial infarction or sudden cardiac death. The treatment strategy depends on the extent and location of the dissection, with revascularization often required to restore adequate coronary blood flow. Various approaches, including percutaneous intervention, may be employed based on the clinical scenario. In this report, we describe a case of successful recanalization following an iatrogenic coronary dissection, emphasizing the importance of early intervention and individualized management.
