Efficacy and safety of the needle rendezvous technique for infrainguinal arterial calcified lesions.

Background: Lower extremity artery disease is increasingly prevalent, and complex lesions such as calcified chronic total occlusions pose significant challenges during endovascular therapy. The needle rendezvous technique, which involves puncturing a needle toward the guidewire within the lesion or lumen and advancing the guidewire into the needle lumen to achieve guidewire externalization, offers a potential solution. If device passage remains challenging, the Rendezvous-PIERCE technique can be subsequently employed by advancing the needle over the externalized guidewire to modify the lesion directly.

Real-time Ripple technique: A case report on Ripple map for real-time identification of conduction gaps without first-pass pulmonary vein isolation.

This paper presents a novel approach to gap mapping in pulmonary vein isolation (PVI) for atrial fibrillation (AF) treatment, utilizing the real-time Ripple (RR) technique. Radiofrequency (RF) catheter ablation, particularly encircling PVI, is a common intervention for AF. Identifying left atrium-pulmonary vein conduction gaps is crucial for achieving PVI with minimal additional ablation if first-pass PVI is unsuccessful.

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.

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.
