Multiple Right Ventricular Pseudoaneurysms Following Helix-Fixation Leadless Pacemaker Implantation

Kosuke Hirose, Satoshi Oka, Nobuhiko Ueda, Akinori Wakamiya et autres

Leadless pacemaker (LP) systems have been widely adopted as an alternative to transvenous pacemaker systems because they eliminate device pocket- and lead-related complications, particularly in elderly or frail patients.1 In Japan, two types of LPs are currently available: tine-fixation and helix-fixation systems. …

The Snare-Assisted Intravascular Lead-to-Wire Conversion technique for venous access preservation during transvenous lead extraction in venous occlusion

Akinori Wakamiya, Yuki Osada, Nobuhiko Ueda, Mitsuru Wada et autres

Venous stenosis or occlusion is a clinically important issue in patients with long-term cardiovascular implantable electronic device (CIED) leads, particularly when lead revision, upgrade, or reimplantation is required.1,2 In patients with ipsilateral venous occlusion, potential strategies include contralateral lead implantation with tunneling, …

Left Ventricular Ejection Fraction Improvement and Ventricular Arrhythmia Risk in Patients With Heart Failure

Toshihiro Nakamura, Kohei Ishibashi, Nobuhiko Ueda, Tsukasa Oshima et autres

BACKGROUND: Implantable cardioverter defibrillators (ICDs) prevent sudden cardiac death in patients with heart failure, but the value of ICD therapy after left ventricular ejection fraction (LVEF) recovery is uncertain. METHODS AND RESULTS: We retrospectively studied 118 patients undergoing primary prevention ICD therapy …
