Hypoxemia Following Surgical Repair Of Partial Anomalous Pulmonary Venous Connection With Interrupted Inferior Vena Cava:Insights From Cardiac Ct, Mahmoud F Elshahat, Ahmed Goha, Naif S. Alghasab, Ahmad Alomrani

Journal of the Saudi Heart Association

Preoperative understanding of complex congenital heart disease is crucial for proper management. Surgical direction of partial anomalous pulmonary venous drainage and atrial septal defect closure when combined by the rare azygos continuation of interrupted inferior vena cava (IVC) may be associated with anomalous systemic to pulmonary venous connection, causing right-to-left shunt. We report a 44-year-old male with a history of congenital heart disease repaired in early childhood. Diagnostic imaging revealed an interrupted IVC with azygos continuation draining into the right upper pulmonary vein to the left atrium. CT play an essential role in recognition of venous anomalies with unexplained cyanosis.

Department of Neurology Faculty Papers

BACKGROUND: Blood pressure (BP) control remains suboptimal in the United States despite available low-cost antihypertensive medications. Even small out-of-pocket medication costs may contribute to adherence. We determined whether $0 versus >$0 out-of-pocket costs for antihypertensive medications is associated with differences in adherence, discontinuation, BP control, and cardiovascular outcomes.

METHODS: We included veterans with newly diagnosed hypertension who initiated antihypertensive medication in the Veterans Health Administration from 2004 to 2022. A fuzzy regression discontinuity design with 2-stage residual inclusion leveraged differences in medication copay policy at a 50% service-connected disability threshold (≥50% service-connected disability: $0 out-of-pocket cost versus < 50%: $8 monthly cost). Outcomes included 1-year medication nonadherence (proportion of days covered < 80%), 1-year medication discontinuation (no medication in the final 90 days of the study year), 1-year BP control (systolic BP/diastolic BP < 140/90 mm Hg and < 130/80 mm Hg) and cardiovascular disease events (myocardial infarction, coronary revascularization, peripheral artery disease, or stroke).

RESULTS: Among 417 …

Heart and Vascular Articles

BACKGROUND: Same-day discharge (SDD) after atrial fibrillation (AF) ablation is generally considered safe, since most complications are identified during (or immediately) after the procedure.

OBJECTIVE: This study aimed to evaluate SDD in the SPHERE Persistent-Atrial Fibrillation trial.

METHODS: Patients with persistent AF were randomized to the dual-energy lattice-tip mapping and ablation catheter (investigational) vs a conventional contact-force radiofrequency ablation system (control). SDD and timing of 30-day procedure- or device-related serious adverse events (SAEs) were assessed in the full cohort. In a subset of centers that performed SDD in the trial, predictors of SDD, 30-day readmissions, and mortality rates were assessed. …

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 …
