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.

Background: Increased risk of thromboembolism during COVID-19 disease is confirmed. Case: A 40-year-old hypertensive otherwise healthy male with COVID-19 disease, presented with exacerbating dyspnea, demonstrated two large mural thrombus in right atrial appendage and right ventricular apex accompanied by pulmonary thromboembolism in imaging studies. He underwent anticoagulant therapy with significant reduction in thrombus sizes. Conclusion: Hypercoagulation state of COVID-19 disease may lead to serious cardiopulmonary injury.
