A case of non-bacterial thrombotic endocarditis on the aortic valve following coronary angiography

TL;DR

This paper reports a case where a heart valve developed blood clots after a heart imaging procedure, leading to a stroke.

Contribution

The paper highlights how catheterization during coronary angiography can mechanically trigger thrombus formation on the aortic valve.

Findings

A 54-year-old man developed non-bacterial thrombotic endocarditis on the aortic valve after coronary angiography.

Surgical removal of the clot was performed due to acute cerebral infarcts.

The case suggests that mechanical trauma from catheterization can lead to thrombus formation.

Abstract

Nonbacterial thrombotic endocarditis (NBTE) on the aortic valve involves fibrin and platelet aggregate formation, potentially leading to embolic events. We present a case of NBTE on the aortic valve following coronary angiography (CAG) in a 54-year-old man with multiple comorbidities. Surgical thrombectomy was performed owing to acute cerebral infarcts. This case highlights the significance of considering that mechanical trauma from catheterization during CAG can trigger thrombus formation.
