Covid-19 And Arrhythmias: A Review Of Cardiac Electrophysiology Associated With Sars-Cov-2, Kashmala Khan, Francis Dimtri, Carlos Vargas, Thomas Alexander

HCA Healthcare Journal of Medicine

Coronavirus infectious disease 2019 (COVID-19) has become one of the most recognized viral illnesses to date. Most people infected with the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) have a benign clinical course, but there have also been catastrophic outcomes. Although, notoriously known to affect the respiratory system, extra-pulmonary manifestations have also been established. An increasing number of people have been reported to present with cardiac manifestations, which include but are not limited to arrhythmias. The cardiac conduction system can be damaged by various mechanisms in patients infected with SARS-CoV-2. In this review, we will attempt to briefly describe the arrhythmogenic …

Characterizing Recurrence Following Hybrid Ablation In Patients With Persistent Atrial Fibrillation, David C. Kress, Lynn Erickson, Tadele W. Mengesha, David Krum, Jasbir Sra

Journal of Patient-Centered Research and Reviews

Purpose: It is It is widely accepted that atrial fibrillation (AF) accounts for half of arrhythmia recurrences following endocardial catheter ablation of AF. An epicardial-endocardial approach (hybrid) has emerged as an alternative to endocardial ablation alone for the treatment of AF, yet recurrence after a hybrid procedure has not been well characterized. This retrospective study is aimed at characterizing recurrence following hybrid ablation for patients with persistent AF.

Methods: Patients with persistent AF (N = 108) received both endocardial and epicardial ablation of the posterior left atrial wall using catheter ablation and a small midline surgical approach (hybrid). Presence of …

Myocardial Work Index: A Novel Method For Assessment Of Myocardial Function In South Asian Recreational Athletes, Shantanu Sengupta, Renuka Jain, Nitin Burkule, Susan Olet, Bijoy K. Khandheria

Journal of Patient-Centered Research and Reviews

Purpose: We used a novel noninvasive method based on speckle-tracking echocardiography to evaluate myocardial performance in South Asian recreational athletes who completed a half marathon.

Methods: Transthoracic echocardiography was performed on 24 recreational athletes 48 hours before they took part in a half marathon (premarathon), within 2 hours of half marathon completion (postmarathon), and 72 hours after completion. Clinical, laboratory, and echocardiographic variables were collected. Speckle-tracking echocardiography was performed in all subjects to characterize myocardial mechanics.

Results: Mean age of participants was 41.8 ± 7.4 years, and 23 (95.8%) were male. No subject had a prior history of coronary artery …
