Abstract:
WPW is a common ventricular preexcitation. The ablation of AP is
successful in more than 90% cases. The presence of PLSVC can impact the
evaluation and treatment of SVAs, it can cause serious complications
during vascular interventional procedures of cardiac anomalies.
We report 2 cases of WPW with PLSVC in whom first ablation was
unsuccessful and after more evaluation LSVC was discovered as second
anomaly. Ablation was tried via CS again; the ablation procedure was
successful.
