Computed Tomography–Derived Abrupt Wall-Thickness Transitions as Complementary Markers of Ventricular Tachycardia Substrate in Ischemic Cardiomyopathy

In this episode, Frank Marchlinski, MD, Deputy Editor of JACC: Clinical Electrophysiology, discusses a study evaluating whether abrupt wall-thickness transitions on cardiac CT scans can help identify critical ventricular tachycardia (VT) substrate in patients with ischemic cardiomyopathy. The investigators found that these CT-derived structural markers frequently co-localized with VT isthmus…
