Low Agreement Among Guidelines for Primary Prevention Implantable Cardioverter-Defibrillator Recommendations in Hypertrophic Cardiomyopathy.

Sudden cardiac death (SCD) risk stratification and primary prevention implantable cardioverter-defibrillator (ICD) recommendations are based on differing strategies for hypertrophic cardiomyopathy (HCM). This study aimed to evaluate the impact of the 2023 European Society of Cardiology (ESC) guidelines on the 2014 ESC and the 2024 American Heart Association (AHA)/American College of Cardiology (ACC) systems in terms of primary prevention ICD recommendations for HCM. A cohort of 200 patients with HCM in Brazil was assessed for SCD risk profile according to current guidelines.

CHA2DS2-VASc score, P-wave indexes, and echocardiographic parameters in sinus rhythm patients without valvular heart disease.

Objective: The aim of this study was to evaluate the correlation between P-wave indexes, echocardiographic parameters, and CHA2DS2-VASc score in patients without atrial fibrillation and valvular disease.

Methods: This retrospective cross-sectional study included patients of a tertiary hospital with no history of atrial fibrillation, atrial flutter, or valve disease and collected data from June 2021 to May 2022. The exclusion criteria were as follows: unavailable medical records, pacemaker carriers, absence of echocardiogram report, or uninterpretable ECG.

Tricuspid Regurgitation and Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis.

Background: The extent of cardiac damage associated with aortic stenosis has important prognostic implications after transcatheter aortic valve replacement (TAVR). However, the role of tricuspid regurgitation (TR) in this clinical setting is still unclear.

Objectives: To explore the association between TR and mortality in patients undergoing TAVR and assess changes in TR severity post TAVR and its relationship with short and mid-term mortality.

F Wave Amplitude as a Predictor of Thromboembolism and Success of Electrical Cardioversion in Patients with Persistent Atrial Fibrillation.

Background: Atrial fibrillation (AF) is classified according to the amplitude of fibrillatory waves (f) into fine waves (fAF) and coarse waves (cAF).

Objectives: To correlate the amplitude of f waves with clinical, laboratory, electrocardiographic, and echocardiographic variables that indicate a high risk of thromboembolism and to assess their impact on the success of electrical cardioversion (ECV).

Methods: Retrospective, observational study that included 57 patients with persistent non-valvular AF who underwent ECV.

Relationship between ventricular repolarization parameters and the inducibility of ventricular arrhythmias during electrophysiological study in patients with coronary artery disease.

Objective: Risk stratification of sudden cardiac death in patients with coronary artery disease is of great importance. We evaluated the association between ventricular repolarization and induction of malignant ventricular arrhythmias on electrophysiological study of patients with coronary artery disease.

Methods And Results: A total of 177 patients (65±10.

Brugada pattern unmasked during COVID-19 infection -:A case report.

The current pandemic caused by the coronavirus disease 2019 (COVID-19) continues affecting millions of people worldwide. Various cardiovascular manifestations have been associated with COVID-19 but only a few case reports of Brugada syndrome in acute respiratory syndrome by SARS-CoV-2 were published. The diagnosis, prognosis, and treatment remain a challenge and represent a concern in terms of management in this population.

The Quality of End-of-Life Care after Limitations of Medical Treatment as Defined by a Rapid Response Team: A Retrospective Cohort Study.

Background: Despite the increase in the identification of patients at the end of life after the introduction of rapid response team (RRT), there is doubt as to whether there has been an improvement in the quality of care offered to these patients. Proper end-of-life care is the next expected step after identifying patients who are dying.

Objective: To evaluate the end-of-life care after limitations of medical treatment (LOMTs) as defined by an RRT.
