Incidence and characteristics of transient St-segment elevation during transseptal puncture.

Purpose: Delineate retrospectively and prospectively the incidence and characteristics of transient ST-segment elevation during transseptal puncture.

Methods: The study retrospectively evaluated 307 patients from January 1, 2015, to December 31, 2017, and prospectively evaluated 231 patients from January 1, 2018, to July 31, 2019.

Results: The presence of ST-segment elevation was significantly higher in the prospective sample than in the retrospective sample (5.

Cryptic, Sympatric Diversity in Tegu Lizards of the Tupinambis teguixin Group (Squamata, Sauria, Teiidae) and the Description of Three New Species.

Tegus of the genera Tupinambis and Salvator are the largest Neotropical lizards and the most exploited clade of Neotropical reptiles. For three decades more than 34 million tegu skins were in trade, about 1.02 million per year.

Luminal esophageal temperature monitoring with a deflectable esophageal temperature probe and intracardiac echocardiography may reduce esophageal injury during atrial fibrillation ablation procedures: results of a pilot study.

Background: Luminal esophageal temperature (LET) monitoring is one strategy to minimize esophageal injury during atrial fibrillation ablation procedures. However, esophageal ulceration and fistulas have been reported despite adequate LET monitoring. The objective of this study was to assess a novel approach to LET monitoring with a deflectable LET probe on the rate of esophageal injury in patients undergoing atrial fibrillation ablation.

[Oral anticoagulation in patients with atrial fibrillation: from guidelines to bedside].

Objective: Although oral anticoagulation has proved beneficial for patients with atrial fibrillation (AF) and embolic risk factors, it is still underused. The objective of this study was to evaluate the adequacy of anticoagulation therapy in patients with AF followed in a private clinic specialized in cardiology, in accordance with the American and European societies of cardiology guidelines/2006 and with the Brazilian Guidelines/2003.

Methods: Between November 2005 and August 2006, we evaluated 7,486 electrocardiograms and selected 53 patients with AF and complete chart records.
