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.
来自心耳的附加旁路（APs）并不常见，主要见于右侧。此外，涉及左心耳（LAA）的连接更为罕见。
本病例报告描述了一名27岁因预激综合征（WPW）导致反复室上性心动过速（SVT）的女性。电生理评估发现双房室（AV）连接：一个来自左心耳，另一个来自左冠状动脉窦（LCC）。
需要更深入地了解WPW综合征的电生理特征。即使在成功消除前向传导后，逆向传导仍可能持续存在。
