This case report describes the previously unrevealed electrophysiological characteristics of a rare left atrial anomalous muscular band in a patient with paroxysmal atrial fibrillation.
Anomalous fibromuscular bands located in the left ventricle or the right atrium have been demonstrated by echocardiography and are reported to have a relationship with specific types of tachycardias. Although a left atrial (LA) anomalous band is found in approximately 2% of the cases by necropsy,1 it is rare to be diagnosed clinically. Therefore, its clinical significance, particularly in the development of atrial fibrillation (AF), is unclear. Furthermore, the electrophysiological characteristics have not been revealed.
