Current state of arrhythmia care in Latin America: A statement from the Latin American Heart Rhythm Society

Latin America is a region that stretches from Mexico to Tierra del Fuego in Argentina and includes much of the Caribbean, with an estimated population of more than 652 million1 and a combined gross domestic product (GDP) of US$5,188,250 trillion.2,3 Arrhythmia care in Latin America has significant variability due to differences in country-specific health care issues, available resources and workforce, and access to medications and technology. In 2022, the Latin American Heart Rhythm Society (LAHRS) began collecting annual information on arrhythmia-related disease burden, availability of specialized therapies for arrhythmias and cardiac implantable electronic devices (CIEDs), and workforce information. The information obtained was presented at a societal meeting held during the 2023 Heart Rhythm Society (HRS) Congress. Herein, we report the final conclusions from the meeting.

Improved All-Cause Mortality with Left Bundle Branch Area Pacing Compared to Biventricular Pacing in Cardiac Resynchronization Therapy: A Meta-Analysis.

Left bundle branch area pacing (LBBAP) has emerged as a physiological alternative pacing strategy to biventricular pacing (BIVP) in cardiac resynchronization therapy (CRT). We aimed to assess the impact of LBBAP vs. BIVP on all-cause mortality and heart failure (HF)-related hospitalization in patients undergoing CRT.

Background

Methods

Studies comparing LBBAP and BIVP for CRT in patients with HF with reduced left ventricular ejection fraction (LVEF) were included. The coprimary outcomes were all-cause mortality and HF-related hospitalization. Secondary outcomes included procedural and fluoroscopy time, change in QRS duration, and change in LVEF.

An unexpected germ: atypical presentation of Vagococcus fluvialis pocket infection in a cardiac pacing device

Advances in cardiac implantable electronic devices (CIED) technology have enabled them to play a relevant role in heart disease. Although complications have decreased, CIED-related infection persists as one of the problems that has the greatest impact on the patient and the health system. Infections due to unusual germs generate additional morbidity and increased costs of care but can have a favorable course with early diagnosis and treatment. The case of a patient with clinical signs and symptoms of CIED pocket infection by Vagococcus fluvialis, without systemic infection or endocarditis, is presented for the first time in the literature. Timely treatment allowed a favorable evolution. New diagnostic and therapeutic challenges come from the hand of more complex patients.

Abstract

Introduction

Advances in cardiac implantable electronic devices (CIED) technology have enabled them to play a relevant role in complex diseases such as heart failure or sudden arrhythmic death. Although complications have decreased, CIED-related infection persists as one of the problems that has the greatest impact on the patient and the health system.

Antibiotic prophylaxis has consistently reduced infection rates and is a settled recommendation. However, various series report current infection rates close to 1-2%. The causative agents are usually Staphylococcus aureus and Staphylococcus epidermidis (or another coagulase-negative). Other infectious microorganisms such as Enterococcus, Streptococcus, Candida, etc. have also been reported. Atypical microorganisms, such as Vagococcus fluvialis, have a different clinical course, from slowly developing infections to rapidly progressive courses.
