Protocol For Non-Invasive Assessment Of Skeletal Muscle Structure And Function In Adolescents With Single Ventricle Heart Disease: A Cross-Sectional, Case-Control Study., Tyler A. Fick, Trent J. Herda, Emily Cramer, David A. White, Daniel Forsha

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Congenital heart disease (CHD) is the most common congenital malformation, and the most severe type, single ventricle (SV) heart disease, requires the Fontan surgical palliation. Fontan palliation minimizes hypoxemia and volume overload by separating systemic and pulmonary circulations, resulting in the absence of a sub-pulmonary pump. Skeletal muscle health may have a greater relative contribution to overall functional capacity of those with SV physiology, via the skeletal muscle (SkM) pump mechanism and oxidative capacity. The purpose of this study is to comprehensively evaluate multiple domains of SkM in this population compared to those with normal cardiac anatomy.

METHODS: Forty …

Acute fulminant myocarditis represents a severe complication of myocarditis, necessitating early suspicion and intervention for improved patient outcomes. Influenza B-induced myocarditis remains a relatively rare entity. A young lady presented to the emergency department with symptoms of heart failure and cardiogenic shock, requiring inotropes without significant improvement. For the continued deterioration of her hemodynamics, she underwent mechanical circulatory support, including Extracorporeal Membrane Oxygenation (ECMO) and Intra-aortic balloon pump (IABP).  The follow-up investigations showed positive influenza B. She was treated with antiviral therapy and steroids, resulting in gradual improvement in hemodynamics and left ventricular ejection fraction

Atrial Fibrillation In Athletes: Mechanisms, Management, And Future Directions, Ibrahim Alameh, Ghina Al Fout, Michael D. Ezekowitz, Mohammed Kamareddine

Department of Medicine Faculty Papers

BACKGROUND: High-volume endurance training may shift exercise from cardioprotective to arrhythmogenic, increasing the risk of atrial fibrillation (AF) in healthy athletes.

CASE SUMMARY: A 38-year-old marathon runner with a 15-year history of high-intensity endurance training presented with episodic palpitations and reduced athletic performance. Electrocardiogram showed paroxysmal AF; echocardiography revealed mild left atrial enlargement without structural heart disease. Symptoms worsened during the recovery phase after runs, suggesting vagally mediated AF. After unsuccessful flecainide therapy, he underwent pulmonary vein isolation. Twelve months later, he remained free of recurrent AF on Holter monitoring and successfully resumed endurance training following an 8-week recovery period. …

Student Papers, Posters & Projects

BACKGROUND: Coronary microvascular dysfunction (CMD) contributes to myocardial ischemia in patients both without obstructive coronary artery disease (e.g., MINOCA/INOCA) and in those with co-existing epicardial stenosis. While its etiology includes structural and functional causes. hematologic parameters have been linked to cardiovascular outcomes. However, the relationship between red blood cell (RBC) markers and microvascular resistance remains poorly characterized. We aim to evaluate whether RBC parameters are correlated with the angiography-derived index of microcirculatory resistance (angio-IMR).

METHODS: This retrospective study evaluated the association between red blood cell (RBC) parameters and angio-IMR in patients with intermediate coronary artery disease (30%-70% stenosis). Data were …
