Ibrutinib-related atrial fibrillation: Therapeutic challenges.

ABSTRACT

Ibrutinib is a drug used in several lymphohyperplastic diseases. Its use is associated with an increased risk of atrial fibrillation. New-onset atrial fibrillation in this setting is a true challenge as several antiarrhythmic drugs are not indicated and long-term anticoagulation has several limitations. Herein, we describe our experience in treating a 55-year-old patient receiving ibrutinib who presented with new-onset atrial fibrillation and borderline arterial pressure. Since first-line therapies, electrical cardioversion and ablation, could not be performed, rhythm control with intravenous administration of amiodarone was attempted and led to prompt sinus rhythm restoration. We discuss the therapeutic challenges related to sinus rhythm restoration and anticoagulation in this group of atrial fibrillation patients.
