# Optical coherence tomography catheter-induced vasospasm of the left anterior descending artery: A case report

## TL;DR

This case report describes a rare complication where an OCT catheter caused vasospasm in the left anterior descending artery, which was resolved with nitroglycerine.

## Contribution

The novelty is the rare documentation of OCT catheter-induced vasospasm in the left anterior descending artery.

## Key findings

- OCT catheter can induce vasospasm in the left anterior descending artery.
- Nitroglycerine administration resolved the vasospasm in this case.

## Abstract

Optical coherence tomography (OCT) helps identify coronary artery disease of different etiologies. Vasospasm from OCT catheter is a rarely reported complication that is more commonly seen in the right coronary artery. We report a case of OCT-catheter induced vasospasm of the left anterior descending artery that resolved with administration of nitroglycerine. Interventionalists need to weary of the occurrence of catheter-related coronary artery spasm to avoid stenting when not necessary.
