Carotid Dissection Complicated by Polymorphic Ventricular Tachycardia

J Stroke Cerebrovasc Dis. 2017 Jun;26(6):e99-e101. doi: 10.1016/j.jstrokecerebrovasdis.2016.12.020. Epub 2017 Apr 5.

Abstract

In this case report, we describe a patient with fibromuscular dysplasia who suffered spontaneous bilateral carotid artery dissections. This was followed by significant variations in blood pressure and heart rates during her admission. Unfortunately, during an episode of bradycardia, a premature ventricular contraction occurred during the T wave which resulted in polymorphic ventricular tachycardia. As described in the case and in graphic depiction, this hemodynamic instability resolved after stenting of the carotid artery.

Keywords: Carotid artery dissection; fibromuscular dysplasia; hemodynamic instability; polymorphic ventricular tachycardia.
