Does radiofrequency linear endocardial ablation control unmappable VT in patients with ischemic and nonischemic cardiomyopathy?
Radiofrequency linear endocardial lesions appear effective for controlling unmappable ventricular tachycardia in patients with ischemic and nonischemic cardiomyopathy.
Radiofrequency linear endocardial lesions extending from the dense scar to the normal myocardium or anatomic boundary seem effective in controlling unmappable VT.
Marchlinski et al. (2000) studied this question.
