Epicardial Ablation of Ventricular Tachycardia by Re-median Sternotomy in a Patient with Double Mechanical Heart Valves / 日本心臓血管外科学会雑誌

ABSTRACT

The patient is a 39-year-old-man who had rheumatic heart disease and had undergone mitral and aortic valve replacements with mechanical St. Jude prostheses as well as tricuspid valve repair and a MAZE procedure 17 years previously. He was admitted with ventricular tachycardia (VT) and an implantable cardioverter-defibrillator (ICD) was implanted. Four months later, he was admitted again with VT, and attempts to manage the VT with drugs were not successful. We performed electro-anatomical mapping and ablation for VT by re-median sternotomy. His postoperative course was uneventful. At 15 months after surgery, no recurrence of VT was recognized.
