title: Ventricular tachycardia in cardiac sarcoidosis controlled by radiofrequency catheter ablation.
abstract: We report a case of a 78-year-old woman with cardiac sarcoidosis with a history of syncope and palpitation. Further assessment with echocardiography, gadolinium-enhanced cardiovascular magnetic resonance (CMR) and histology led to a diagnosis of cardiac sarcoidosis. As the patient suffered from ventricular tachycardia (VT) despite active corticosteroid therapy, an implantable cardioverter-defibrillator (ICD) was positioned. She was also administered a beta blocker, but an electrical storm appeared every several days requiring ICD therapy. The drug-refractory VT was finally controlled with a catheter ablation session, during which we could detect the VT focus in the right ventricular outflow tract next to the aneurysm by using an electroanatomic mapping system (CARTO). Referring to echocardiographic and CMR images proved very useful in detecting the aneurysm using the CARTO system.
