Translational Anatomy of the Sinoatrial Node: Myoarchitecture and its Relevance for Catheter Ablation

Year: 2025

Type: article

Abstract: ANATOMY: Clinical applications relevant to the sinoatrial node anatomy for interventional electrophysiology procedures are reviewed. PATHOLOGY: Inappropriate sinus tachycardia, atrial tachycardia, and superior vena cava triggers for atrial fibrillation. IMAGING CORRELATION: Three-dimensional electroanatomic mapping, intracardiac echocardiography. TREATMENT: Ablation guided by activation mapping and intracardiac electrograms. TAKE-HOME MESSAGE: Understanding the anatomy of the sinoatrial node and the perinodal region provides key anatomic concepts to safely and effectively guide ablation procedures.
