Reduced Left Atrial Appendage Flow Velocity as a Risk of Thromboembolic Events After Catheter Ablation of Atrial Fibrillation

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Reduced preprocedural LAAFV is associated with adverse long‐term clinical outcomes after AF ablation, including a significantly increased risk of thromboembolic events. ABSTRACT Background Reduced left atrial appendage flow velocity (LAAFV) on transesophageal echocardiography (TEE) is recognized as a predictor of thromboembolic events (TEs) in patients

The Clinical Utility of 3D Electroanatomical Mapping for Atrial Fibrillation Ablation by Pulsed Field Ablation

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Systematic high‐density 3D electroanatomical remapping during pulsed field ablation detected residual conduction in 9% of cases, predominantly in the right superior pulmonary vein. Detailed voltage analysis demonstrated sharp 1 mm lesion borders, highlighting the value of 3D mapping for assessing lesion integrity and procedural endpoints in pulsed ...

Persistent Left Superior Vena Cava and Absent Right Superior Vena Cava with Left Subclavian Vein Stenosis: Technical Challenges with Pacemaker Implantation

Case Reports in Cardiology, 2019
We present a challenging case of a 75-year-old female with a history of paroxysmal atrial fibrillation (PAF) and symptomatic sick sinus syndrome (SSS) who presented for a dual chamber pacemaker implantation and was found to have persistent left superior ...

Pulmonary Vein Isolation Using a Circular Multielectrode Pulsed Field Ablation Catheter via a Jugular Vein Approach

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
PVI by catheter ablation for atrial fibrillation via a superior approach is technically challenging. However, the circular multielectrode PFA catheter is feasible for PVI via a superior jugular vein approach. AP, anteroposterior; LAO, left anterior oblique; PA, posteroanterior; PFA, pulsed field ablation; PVI, pulmonary vein isolation.

Percutaneous stenting of malignant superior vena cava syndrome in a patient with persistent left and absent right superior vena cava

Journal of Interventional Medicine, 2018
: Stent placement is the preferred means of managing malignant obstruction of the superior vena cava (SVC). Persistent left and absent right SVC is a very rare venous anomaly.

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

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Pulsed field ablation at the right superior pulmonary vein frequently causes conduction delay or partial isolation of the superior vena cava. Anatomical proximity between the two structures, as assessed by preprocedural CT, predicts the likelihood of SVC involvement.

Right-sided superior vena cava draining into the left atrium in a patient with persistent left-sided superior vena cava emptying into the right atrium: a case report

The Egyptian Journal of Radiology and Nuclear Medicine
Background A wide range of congenital and acquired abnormalities can impact the superior vena cava (SVC), with some remaining asymptomatic. The most common anomaly is the persistent left SVC draining into the coronary sinus or right atrium, while the ...

Prenatal Diagnosis of Joubert Syndrome 23 With Left Isomerism: A Novel Phenotype Associated With Pathogenic KIAA0586 Variant

Prenatal Diagnosis, Volume 45, Issue 13, Page 1783-1786, December 2025.
Abstract Joubert syndrome is a rare autosomal recessive ciliopathy defined by the “molar tooth” sign caused by cerebellar vermis hypoplasia and abnormal superior cerebellar peduncles. Over 40 genes are known to cause the disorder, including KIAA0586, which encodes the centrosomal protein TALPID3, essential for ciliogenesis and Hedgehog signaling ...
