Abstract
Accessory pathways (APs) from the atrial appendage are uncommon and primarily described on the right side. Furthermore, connections involving the left atrial appendage (LAA) are even rarer. This case report describes a 27-year-old female with recurrent supraventricular tachycardia (SVT) due to Wolff-Parkinson-White (WPW) syndrome. Electrophysiological evaluation identified dual atrioventricular (AV) connections: one from the LAA and another from the left coronary cusp (LCC). The electrical characteristics of WPW syndrome need a deeper understanding. The retrograde conduction can persist even after successfully eliminating the antegrade conduction.
