Intracardiac thrombi fluttering like hair in the wind at VT ablation

J Cardiovasc Electrophysiol. 2023 Nov;34(11):2403-2405. doi: 10.1111/jce.16079. Epub 2023 Oct 3.


Introduction: Intracardiac echocardiography (ICE) reveals mobile thrombus on implantable electronic device leads in some patients undergoing electrophysiologic procedures.

Methods: ICE was performed in a patient undergoing ventricular tachycardia (VT) ablation.

Results: ICE showed extensive mobile thrombi on the implantable cardioverter defibrillator lead. Radiofrequency catheter ablation of VT from perimitral scar was safely performed via a retrograde aortic approach. After the procedure, chronic anticoagulation was initiated. CT-angiography of the chest 2 months later showed no pulmonary emboli.

Conclusions: The significance of these thrombi, as related to chronic pulmonary embolization, warrants further study.

Keywords: ablation; device; thrombi; ventricular tachycardia.
