The Right Ventricular Moderator Band: From Leonardo da Vinci's Drawings to Current Cardiac Imaging.

ABSTRACT: We aim to review the anatomy of the moderator band (MB) and the trabeculated right ventricle (RV). We thoroughly describe the morphological variations of the MB and its spatial relationship with the right ventricular anterior papillary muscle, its muscular trabeculations, and the free wall. We provide echocardiography, computed tomography, and magnetic resonance imaging to better understand histologic specimens of the MB, the trabeculated RV, and the right ventricular papillary muscles. We provide examples of intracardiac echocardiography and transesophageal echocardiogram to guide safe and effective structural interventions in the RV, and mapping and ablation of ventricular arrhythmias arising from the MB.
