Persistent left sided superior vena cava [PDF]

Heart, 2006
A 63 year old woman with hypertension presented with intestinal obstruction. A central venous catheter (CVC) was placed into the left internal jugular vein after initial attempts on the right internal jugular failed. A chest radiograph post-procedure showed the tip to be in an unusual position (panel A). Blood …

Active fixation of bipolar left ventricular lead through a persistent left superior vena cava

Journal of Arrhythmia, 2022
A left superior vena cava persistence was found in a 61 year‐old patient affected by dilated and hypokinetic cardiopathy with severe dysfunction of the left ventricle (left ventricular ejection fraction of 32%) and valvular disease.

Low voltage‐guided ablation of posterior wall improves 5‐year arrhythmia‐free survival in persistent atrial fibrillation

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2475-2484, December 2022., 2022
Abstract Introduction The posterior wall (PW) has been proposed as a standard target for ablation beyond pulmonary vein antral isolation (PVI) in patients with persistent atrial fibrillation (AF). However, studies have shown inconsistent outcomes with the addition of PW ablation.

AV‐node isolation as an alternative to AV‐node ablation in patients undergoing pace & ablate strategy

Journal of Cardiovascular Electrophysiology, Volume 33, Issue 12, Page 2606-2613, December 2022., 2022
Abstract Introduction Atrioventricular (AV)‐node ablation (AVNA) is a common therapy option for rate control strategy of permanent atrial fibrillation (AF). We hypothesized that isolation of the AV nodal isolation (AVNI) is associated with a more frequent preservation of an adequate escape rhythm compared to AVNA.

Gradual diagnosis and clinical importance of prenatally detected persistent left superior vena cava with absent right superior vena cava – a case report and literature review

Journal of Ultrasonography, 2020
Persistent left superior vena cava is a malformation of cardinal veins. We report a case of a secundigravida who had many fetal ultrasound examinations – first performed by an obstetrician (who described fetal mediastinum as “abnormal”), second by other ...

An adult with left isomerism having an interrupted inferior vena cava and persistent left superior vena cava associated with partial atrioventricular canal defect and complete heart block — a case report

The Cardiothoracic Surgeon, 2022
Background Persistent left superior vena cava is a well-recognized thoracic venous abnormality, most of which do not present with any symptoms. Its opening into the left atrium is uncommonly encountered and, if present, is noted to be associated with ...

Estimation and Tracking of AP-diameter of the Inferior Vena Cava in Ultrasound Images Using a Novel Active Circle Algorithm [PDF]

In Computers in Biology and Medicine, vol. 98, pp. 16-25, July 2018, 2018
Medical research suggests that the anterior-posterior (AP)-diameter of the inferior vena cava (IVC) and its associated temporal variation as imaged by bedside ultrasound is useful in guiding fluid resuscitation of the critically-ill patient. Unfortunately, indistinct edges and gaps in vessel walls are frequently present which impede accurate estimation

3D mapping of phrenic nerve course for radiofrequency pulmonary vein isolation

Journal of Cardiovascular Electrophysiology, Volume 34, Issue 1, Page 90-98, January 2023., 2023
Abstract Introduction Phrenic nerve (PN) injury is a rare but severe complication of radiofrequency (RF) pulmonary vein isolation (PVI). The objective of this study was to characterize the typical intracardiac course of the PN with a three‐dimensional electroanatomic mapping system, to quantify the need for modification of the ablation trajectory to ...

A sharp interface Lagrangian-Eulerian method for flexible-body fluid-structure interaction [PDF]

, 2022
This paper introduces a sharp-interface approach to simulating fluid-structure interaction involving flexible bodies described by general nonlinear material models and across a broad range of mass density ratios. This new flexible-body immersed Lagrangian-Eulerian (ILE) approach incorporates the geometrical and domain solution flexibility of the ...
