## TL;DR

A 21-year-old woman with a rare heart condition and a patent foramen ovale experienced an embolic stroke and was treated with device closure and anticoagulation.

## Contribution

This case highlights the association between Cor triatriatum sinister and embolic stroke, emphasizing the need for further research on its mechanisms and treatment.

## Key findings

- CTS was found to be unobstructed in a patient with embolic stroke.
- The patient had a patent foramen ovale, which was closed as part of treatment.
- Further study is needed to understand the role of CTS in stroke and optimal therapies.

## Abstract

Cor triatriatum sinister/echocardiogram and cardiac computed tomography.

The patient was a 21-year-old woman with an embolic stroke who was found to have an unobstructed Cor triatriatum sinister (CTS) and patent foramen ovale and underwent a patent foramen ovale device closure and subsequent anticoagulation therapy. Case reports of CTS associated with stroke have been previously published, and CTS is recognized as a risk factor for an embolic stroke; however, the mechanism of embolic stroke is unclear.

Further study is warranted to understand the mechanism and role of CTS for embolic stroke and optimal therapeutic options to reduce the risk of recurrent stroke.
