There are several technical options, such as endocardial cryoablation alone, endo- and epicardial cryoablation, direct clamping of the CS with a Bipolar RF device and cryo or RF at the isthmus, for creating a conduction block at the CS/mitral isthmus region. Was there any association with the incidence of failure at the CS/mitral isthmus region and the ablative procedures used to create the lesion?
