A narrow complex tachycardia with a short HV interval: What is the mechanism?
Pacing Clin Electrophysiol
January 2025
Division of Cardiology, the First Affiliated Hospital of Nanjing Medical University, Nanjing, China.
The case was a 15-year-old male with a history of paroxysmal supraventricular tachycardia refractory to medical therapy and prior catheter. A repeat electrophysiology study and catheter ablation were applied. Baseline AH and HV intervals were 100 and 55 ms during normal sinus rhythm (NSR), respectively.

We present a patient with a history of heart failure and metallic aortic and mitral valves surgeries, who required ablation for a drug-refractory left ventricular tachycardia. But the metallic valves prohibited the insertion of catheters via retrograde or via trans-septal approaches. Therefore, we decided to perform catheter ablation by direct left ventricle puncture through a minithoracotomy.

Recently, alternatives to intranasal packing following septoplasty and rhinoseptoplasty have been widely used and promoted. Here, we aimed to systemically review and compare the different types of nasal packing used in these two surgeries. To assess patient comfort and surgical outcomes, we conducted a comprehensive search of multiple databases such as PubMed, MEDLINE, Web of Science, and Google Scholar to identify and evaluate relevant articles.

J Endovasc Ther
June 2024
Interventional Cardiology Unit, Department of Cardiac, Thoracic, Vascular Sciences and Public Health, University of Padua, Padua, Italy.
Purpose: The purpose of this article is to describe an emergent in situ fenestration (ISF) technique in the ascending aorta for the endovascular repair of a large pseudoaneurysm using a trans-septal needle device through direct right common carotid artery access, in a patient with left ventricular assist device (LVAD).
Technique: We performed, in a multidisciplinary team-work approach, an emergent ISF to correct the displacement of a physician-modified thoracic endograft released in the ascending aorta to correct a large anastomotic pseudoaneurysm in a patient who underwent ascending aorta replacement and subsequent LVAD implantation. We used a trans-septal needle device inserted through a direct access to the right carotid artery and performed an ISF to restore the patency of the outflow ostium of the LVAD.
Zero-fluoroscopy ablation in patients with cardiac electronic implantable devices.

Department of Cardiovascular Medicine, National Cerebral and Cardiovascular Center, Suita, Osaka, Japan.
Introduction: Utilizing a three-dimensional (3-D) mapping system and intracardiac echocardiography (ICE) has allowed ablation procedures with less or without fluoroscopy; however, there is limited data for patients with cardiac electronic implantable device (CIED) leads regarding the suspected risk of lead injury. Therefore, we sought to explore technics to perform safe trans-septal approach and catheter manipulation technique in patients with CIED leads.
Methods And Results: This study comprised 49 consecutive patients (59% males, median 73 years old) with CIED who underwent catheter ablation for supraventricular tachycardia requiring the trans-septal approach, 15 without fluoroscopy (zero-fluoro group), and 34 with fluoroscopy (conventional-fluoro group), between July 2019 and April 2021.
