This report illustrates the technique of site-selective atrial septal puncture to facilitate catheter access for mapping and ablation.
Atrial transseptal puncture is a technique that provides pervenous access to the left heart. The aim of this technique is to provide catheter access to the left atrium and ventricle for mapping, as well as stable electrode-endocardial contact for ablation energy application. In the present report, "site-selective" atrial septal puncture is described and illustrated using case reports.
Bazaz et al. (Sat,) studied this question.
