Improvement in respiratory function and exercise tolerance following video-assisted thoracoscopic diaphragm plication for symptomatic iatrogenic persistent diaphragm paralysis after radiofrequency catheter ablation.

Hemidiaphragm paralysis, a complication of catheter ablation for atrial fibrillation, can severely affect respiratory function and can lead to paradoxical breathing and dyspnea on exertion. A 75-year-old woman with iatrogenic diaphragm paralysis showed improved symptoms, respiratory function, and exercise tolerance after video-assisted thoracoscopic diaphragm plication.

Successful transvenous retrieval of an electrode ring dislodged from a novel visualized steerable sheath by inflation of a balloon inside the ring.

Unlabelled: The VIZIGO sheath (Biosense Webster, Irvine, CA, USA) is used for catheter ablation (CA) of atrial arrhythmia. In this case report, we describe a complication associated with the VIZIGO sheath and present a successful bailout method. An 82-year-old woman with paroxysmal atrial fibrillation (AF) and atrial tachycardia (AT) was referred to our hospital after experiencing palpitations for 6 months.

Lock and dock: Two-step transvenous retrieval of a fractured femoral sheath with a vascular snare via the right internal jugular vein.

Unlabelled: An 86-year-old male with progressive palpitations and dyspnea was referred to our hospital for heart failure treatment. Catheter ablation was performed for atrial flutter as we suspected tachycardia-induced cardiomyopathy as the cause of the patient's heart failure. Due to difficulty securing a peripheral venous route, a 6-Fr sheath was inserted via the right common femoral vein prior to administering general anesthesia.

Oversensing caused by trapped air in the header of subcutaneous cardioverter-defibrillator generator.

In this study, we report two cases with oversensing due to air accumulation in the subcutaneous implantable cardioverter-defibrillator (S-ICD) device generator header. If trapped air in the header of the device is suspected, the re-connection procedure should be considered or the primary vector must be used, which might prevent oversensing.

Wire ThRoUgh Snare Twice (Wire TRUST) technique: A novel method to grasp a lead with inaccessible ends as a supportive femoral approach for transvenous lead extraction.

Introduction: Transvenous lead extraction (TLE) is a crucial procedure for managing cardiac implantable electronic devices. The use of a combined superior and femoral approach has been found to enhance the success rate of TLE. This report introduces a novel technique, named "Wire ThRoUgh Snare Twice" (Wire TRUST), for effectively grasping a lead without a free end during TLE.

Rocket-shape crossing technique: A combination of lead extraction and modified venoplasty for device upgrade with venous occlusion.

This case discusses an upgrade method to cardiac resynchronization therapy defibrillator for a 54 year old man with superior vena cava occlusion. Right ventricular lead extraction with modified venoplasty, Rocket shape Crossing Technique (RCT), was performed. In RCT the integration of the inflated balloon, halfway inside the laser sheath, and the laser sheath are advanced through the occlusion like a rocket shape crossing.

Predictors of Pacing Capture Threshold Exacerbation After Leadless Pacemaker Implantation.

The predictors of pacing capture threshold (PCT) exacerbation after leadless pacemaker implantation remain unknown. We analyzed the predictors of poor PCT by identifying risk factors using multivariate logistic regression analysis for 211 patients with leadless pacemaker implantation. Twenty patients met the criteria for elevated PCT levels and were categorized in the poor PCT group.
