Cavotricuspid Isthmus-Dependent Atrial Flutter. Beyond Simple Linear Ablation.

The demonstration of a peritricuspid circular movement with a zone of slow conduction in the cavotricuspid isthmus, together with the high efficacy of linear ablation and widely accepted acute endpoints, has established typical flutter as a disease with a well-defined physiopathology and treatment. However, certain aspects regarding its deeper physiopathology, ablation targets, and methods for verifying the results remain to be clarified. While current research efforts have primarily been focused on the advancement of effective ablation techniques, it is crucial to continue exploring the intricate electrophysiological, ultrastructural, and pharmacological pathways that underlie the development of atrial flutter.

Myocarditis in a young male affected with monkeypox infection: a case report.

Background: Concerns on monkeypox as a disease impacting global public health first emerged in May, 2022, and, since that time, has been identified in more than 50 countries. The condition mainly affects men who have sex with other men. Cardiac disease is a rare complication of monkeypox infection.
