Bilateral Absence of the Superior Vena Cava

open access: yesCase Reports in Cardiology, 2012
Bilateral absence of the superior vena cava (SVC) is a very rarely detected, mainly asymptomatic congenital vascular anomaly. Though usually innocent, this anomaly may complicate cardiothoracic surgery and certain procedures like central venous catheter ...

5D Flow MRI Reveals Respiration‐Driven Changes in Blood Flow Energetics in Congenital Heart Disease

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Hemodynamic monitoring is essential for patients with right‐sided congenital heart disease (CHD). Respiration may have an increased impact on pulmonary flow in these patients that cannot be assessed by standard tools including 4D flow MRI. This study uses 5D flow MRI to assess respiratory‐cycle variations in flow energetics in patients

Duplication of the Superior Vena Cava in an Elderly Patient on Hemodialysis

open access: yesInternational Journal of Gerontology, 2017
Summary: The prevalence of elderly patients who are dependent on hemodialysis (HD) has increased worldwide. We report the case of an 81-year-old man with end-stage renal disease who displayed a duplication of the superior vena cava (SVC) with bilateral ...

Optimizing Research Operations and Resource Utilization in ALS Care: Insights From the Tofersen Antisense Oligonucleotide Expanded Access Protocol

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Tofersen is a gene‐targeted therapy for individuals with superoxide dismutase 1 (SOD1) (+) amyotrophic lateral sclerosis (ALS). Prior to U.S. Food and Drug Administration (FDA) approval, tofersen was made available through expanded access protocol.

Beyond the Pulmonary Veins: The Influence of Pulsed Field Ablation on the Superior Vena Cava

open access: yesJournal of Arrhythmia
Background Pulsed field ablation (PFA) selectively ablates myocardial tissue while minimizing damage to surrounding structures. However, its effects on the superior vena cava (SVC) during right superior pulmonary vein (RSPV) isolation remain unclear ...

Benefits of Main Reactor based SVC in utility applications [PDF]

open access: yes, 2016
This thesis focuses on static reactive power compensators in utility applications. The objectives for the thesis are to disclose the benefits of the Main Reactor based Static VAr compensator (SVC) compared to the conventional SVC, to find out the most ...

The anastomotic location between SVC and PA.

open access: yes, 2014
A. Multiplanar reformation image shows that SVC was above PA when it located at ten to two o'clock of PA on the sagittal section. B. Multiplanar reformation image shows that SVC was beside PA at six to twelve o'clock of PA on the sagittal section.

At‐Home Versus in‐Clinic Vital Capacity Measurement: Insights From the HEALEY ALS Platform Trial

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Respiratory weakness, typically monitored as vital capacity (VC), is a central feature of amyotrophic lateral sclerosis (ALS). VC is increasingly measured remotely in participants' homes, although in‐clinic assessment remains the standard.

Feasibility and Safety of High-Power Settings for Electrical Isolation of the Superior Vena Cava Using a Catheter Capable of Local Impedance and Contact Force Monitoring. [PDF]

open access: yesJ Arrhythm
High‐power superior vena cava isolation using a contact force– and local impedance–sensing catheter achieved safe and consistent first‐pass isolation. Local impedance decreased more rapidly than generator impedance, accurately reflecting effective lesion formation and enabling reliable real‐time assessment in thin SVC myocardium.
