Eligibility criteria

Inclusion criteria

* Patients with confirmed diagnosis of CLL who are planned to start either ibrutinib or acalabrutinib per standard of care, in monotherapy or in combination with an anti-CD20 antibody, venetoclax, and/or a PI3K inhibitor. Both treatment-naïve and relapsed or refractory CLL are allowed.
* No known history of paroxysmal, persistent, or permanent atrial fibrillation. Exception: The study allows enrollment of up to 10 patients with a known history of paroxysmal atrial fibrillation (exploratory cohort).
* No known history chronic symptomatic congestive heart failure or documented ejection fraction \< 50%.
* Creatinine ≤ 1.5x institutional upper limit of normal (ULN). An adequate kidney function is necessary to ensure safety of IV contrast given before cardiac MRI.
* Age ≥18 years.
* ECOG performance status ≤2 (Karnofsky ≥60%).

Exclusion criteria

* Prior exposure to ibrutinib or acalabrutinib.
* Patients with a clinical contraindication to MRI.
* Patients with childbearing potential who cannot or do not wish to use an effective method of contraception, during the study period and for 12 months after the final treatment used for the purposes of the study.
