Fig. 2. (A, B) The microwave device offered controlled, localized energy delivery, which may reduce the risk of stimulating arrhythmia and damaging adjacent neural structures such as the phrenic nerve. (C) Pericardiectomy, pericardiotomy, and epicardial crosshatching incision using the microwave device. (D) Effective use of a microwave ablation device for pericardial resection.
