Ultra-High-Density Catheter Ablation of Purkinje Premature Ventricular Contractions Causing Electrical Storm.
JACC Case Rep
January 2025
Hospital Clínico Universitario Lozano Blesa, Zaragoza, Spain.
The postacute myocardial infarction electrical storm is a life-threatening entity. Resistance to ischemia in Purkinje fibers may be the origin of short-coupled premature ventricular contractions that trigger severe arrhythmic events. We present a case where the use of emergency catheter ablation, guided by a 3D navigation system and an ultra-high-density mapping catheter, successfully terminated the arrhythmic storm.

Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH).
Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at our hospital from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided transforaminal endoscopic lumbar discectomy (Ng-TELD) group (30 cases), while those treated with the conventional X-ray fluoroscopy method were defined as the control group (31 cases).

The integration of robotic systems in image-guided trans-arterial interventions has revolutionized the field of Interventional Radiology (IR), offering enhanced precision, safety, and efficiency. These advancements are particularly impactful for acute conditions such as stroke, pulmonary embolism, and STEMI, where timely intervention is critical. Robotic platforms like the CorPath GRX and Magellan allow for remote navigation and catheter-based interventions, making it possible to extend specialized services to remote and underserved areas.
