Enhanced Procedural Efficacy in Typical Atrial Flutter Ablation With a Visualizable Steerable Sheath.
Pacing Clin Electrophysiol
January 2025
Department of Cardiology, Yan'an Hospital Affiliated to Kunming Medical University, Kunming, Yunnan, P.R. China.
Objective: The Vizigo sheath, a novel visualizable steerable sheath, has been utilized effectively in the clinical management of atrial fibrillation. However, its application in the ablation of typical atrial flutter (AFL) remains unexplored. This study aims to evaluate and compare the efficacy and safety of the Vizigo sheath against a conventional fixed sheath during catheter ablation for typical AFL.

Introduction: A leadless pacemaker (LLPM) was recommended for a patient with intermittent complete heart block and near-syncope.
Methods And Results: Delivery of LLPM is through a large sheath that has limited deflection and steerability. This report describes the successful deployment of a ventricular LLPM in a patient with prior surgical correction of AV septal defect with subsequent significant right atrial enlargement.
A self-expandable nitinol frame for cable-driven parallel mechanisms in minimally invasive cardiovascular interventions.

The integration of self-expandable nitinol frames with cable-driven parallel mechanisms offers a promising advancement in minimally invasive cardiovascular interventions. This study presents the design, fabrication, and verification of a miniaturized self-expandable nitinol frame to enhance catheter tip steerability and navigation within complex vascular anatomies. The frame is reduced in size for delivery through 7-8 Fr sheaths while accommodating diverse vascular diameters, allowing up to a maximum expansion of 15 mm.

Background: The new Amplatzer Steerable Delivery Sheath is a delivery system designed to improve ease-of-use and procedural results of left atrial appendage closure (LAAC). We aimed to compare procedural results after switching our LAAC program at a tertiary care center with the Amulet device to the Steerable Delivery Sheath, with a control group of LAAC employing the standard sheath.
Methods: The first n = 32 consecutively treated patients at our site using the Amulet device with the Steerable Delivery Sheath were included in this retrospective analysis.
Antegrade Fenestration During Thoracic Endovascular Aortic Repair for Preserving Isolated Left Vertebral Artery.
EJVES Vasc Forum
October 2024
Department of Vascular Surgery, The First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, China.
Article Synopsis
- An isolated left vertebral artery (ILVA) is often affected by aortic arch pathologies, and preserving its blood flow during endovascular repair can be challenging, with no clear consensus on the best strategy.
- This case report details a successful endovascular procedure in a 72-year-old man with an ILVA, where a novel technique called antegrade needle-assisted fenestration was used to revascularize the artery without traditional surgical methods.
- The patient had a favorable outcome, with follow-up imaging showing a patent ILVA and good aortic remodeling, suggesting this technique could be a valuable option for similar cases.
