Ibrutinib-Associated Cardiovascular Events in a Patient Wearing an Implanted Loop Recorder

Ibrutinib is a well-tolerated and effective therapy used for the treatment of chronic lymphocytic leukemia (CLL). However, its use has been associated with cardiovascular events such as atrial fibrillation (Afib), hypertension, and ventricular arrhythmias. Cardiac arrhythmias represent a significant cause of morbidity and mortality. Implanted loop recorders have been integrated into our clinical practice and have been considered a useful tool in guiding the management of patients with cardiac arrhythmias. We report a case that describes our experience on a patient diagnosed with CLL treated with ibrutinib.
