Wolf Parkinson White Accessory Pathway Ablation Via Sinus Coronary in Patient with Left Persistent SVC: 2 Case Report

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.
