Correlation of inflammation due to cardiac sarcoidosis by positron emission tomography-computed tomography imaging and endocardial voltage mapping in a patient with recurrent ventricular tachycardia

摘要

A 48-year-old man with cardiomyopathy and sarcoidosis presented with ventricular tachycardia (VT). He underwent an electrophysiology study with mapping which demonstrated low voltage (red regions in panel A, left) along the mitral, tricuspid annulus and septum. Catheter ablation was performed at sites with fractionation, diastolic potentials and excellent pace maps (red dots in panel A, left).
