Multimodality Imaging and Pace-Mapping Patterns in Patients With Cardiac Sarcoidosis and Ongoing Inflammation Undergoing Ventricular Tachycardia Ablation | JACC: Clinical Electrophysiology

In this episode, Frank Marchlinski, MD, Deputy Editor of JACC: Clinical Electrophysiology, discusses a study of ventricular tachycardia ablation in patients with active cardiac sarcoidosis. Using integrated FDG-PET and cardiac MRI imaging, the investigators found that VT exit sites were often located in areas of active inflammation, while more proximal circuit sites were associated with scar. Patients in whom only VT exit sites could be identified had substantially higher VT recurrence rates, suggesting that targeting deeper portions of the VT circuit may improve outcomes.
