Abstract

ALTAMAR, Jhan et al. Identification of an anatomical variant in the successful ablation of a typical atrial flutter after valve surgery: Usefulness of intracardiac echocardiography. Rev. Colomb. Cardiol. [online]. 2019, vol.26, n.2, pp.107-110. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2018.08.005.

A three-dimensional ablation of an atrial flutter, dependent on the cavo-tricuspid isthmus, was performed on a patient with previous tricuspid valve surgery. The use of intracardiac echocardiography enabled a saccular structure to be identified in the septal aspect of the isthmus. After the ablation in this point, the flutter stopped and a two-directional block was confirmed. This report suggests, furthermore, that the atrial myocardium together with the valvular ring, serves as a critical conduction pathway of the atrial flutter.
