Core Tip: New medications to treat atrial fibrillation (AF) without causing ventricular arrhythmias are urgently needed. However, access to atrial human tissue is restricted, a problem that may be largely addressed by the general availability of human induced pluripotent stem cell derived atrial cardiomyocytes (hiPSC-aCMs), which provide an excellent opportunity to investigate the pathophysiology of AF and the efficacy and toxicity of treatment options. The primary drawback of using hiPSC-aCMs is their immature phenotype. Several laboratories are researching CM maturation techniques, including culture conditions, electrical stimulation, and biophysical and biochemical features. The current strategies being investigated for use in the maturation of patient-specific hiPSC-aCMs and their application towards a tailored strategy for the pharmacologic management of AF are covered in this review.
