Abstract
Resumen: Se hizo ablación tridimensional de aleteo auricular, dependiente del istmo cavotricuspídeo, en un paciente con cirugía previa de válvula tricúspide. El uso de ecocardiografía intracardiaca permitió identificar una estructura sacular en el aspecto septal del istmo. Después de la ablación en este punto, el aleteo terminó y se confirmó bloqueo bidireccional. Este reporte sugiere, además, que el miocardio auricular ligado al anillo valvular, sirve como vía de conducción crítica del aleteo auricular. Abstract: 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.
