Key result
Radiofrequency ablation lesions in a human myocardial infarct had sufficient depth (up to 3 mm) but lacked the width (2x2 to 5x10 mm) to interrupt broad sheets of myocytes in the reentry circuit.
Case Report (n=1)
Histologic analysis of RF lesions in a human myocardial infarct shows they have sufficient depth but may lack the width to interrupt broad sheets of myocytes in VT reentry circuits.

RF lesions may lack width to transect infarct VT circuits; case report leaves open optimal ablation geometry.
Bartlett et al. (1995) conducted a case report in Ventricular tachycardia late after myocardial infarction (n=1). Radiofrequency (RF) ablation was evaluated on Histologic characteristics of RF lesions. Radiofrequency ablation lesions in a human myocardial infarct had sufficient depth (up to 3 mm) but lacked the width (2x2 to 5x10 mm) to interrupt broad sheets of myocytes in the reentry circuit.
