National Tunisian Study of Cardiac Implantable Electronic Devices: Design and Protocol for a Nationwide Multicenter Prospective Observational Study.

Background: In Tunisia, the number of cardiac implantable electronic devices (CIEDs) is increasing, owing to the increase in patient life expectancy and expanding indications. Despite their life-saving potential and a significant reduction in population morbidity and mortality, their increased numbers have been associated with the development of multiple early and late complications related to vascular access, pockets, leads, or patient characteristics.

Objective: The study aims to identify the rate, type, and predictors of complications occurring within the first year after CIED implantation.

Clinical and electrophysiological profile of Brugada syndrome in the Tunisian population.

Background: Most clinical studies of the clinical profile of Brugada syndrome (BS) have been conducted in either Asia, Europe, or America and their applicability to North African populations is largely unknown. The aim of the study was to analyze the clinical profile of BS in Tunisian patients.

Methods: The clinical and follow-up data of 24 patients (22 men, mean age: 40.

Potential danger of ocular compression in paroxysmal supraventricular tachycardia in patients with latent preexcitation.

The vagal maneuver is the first line of therapeutic available for patients with paroxysmal supraventricular tachycardia. It increases vagal tone and includes the traditional ocular compression, carotid sinus massage, and Valsalva maneuver. A 40-year-old man was admitted because of 180 beats/min regular narrow QRS-complex tachycardia.

Left main coronary thrombosis: unusual complication after radiofrequency ablation of left accessory atrioventricular pathway.

Radiofrequency ablation (RFA) has established itself as a first-line therapy for the curative treatment of many patients with supraventricular or atrioventricular tachycardias and has exhibited a generally low incidence of serious sequelae (N Engl J Med. 1991;324:1612; Lancet. 1991;337:1557).

Total absence of ST-segment resolution after failed thrombolysis is correlated with unfavorable short- and long-term outcomes despite successful rescue angioplasty.

Introduction: ST-segment resolution (STR) is a well-established and simple tool for assessing the efficacy of reperfusion therapy in myocardial infarction. An incomplete (<50%) STR is a recognized marker of failed thrombolysis and a suitable recruitment criterion for rescue angioplasty.

Objective: We sought to determine the predictive value of the total absence of STR after thrombolysis in rescue angioplasty (percutaneous coronary intervention [PCI]).
