Abstract Introduction Negative component abolition of the unipolar signal (unipolar modification [USM]) reflects lesion transmurality. The purpose this study was to compare procedural safety and outcome between high‐power conventional‐power atrial radiofrequency applications during a pulmonary vein isolation (PVI) using USM as local endpoint. Methods Results High‐power (50 W) (25‐40 were compared among 120 consecutive patients with paroxysmal fibrillation who underwent USM‐guided PVI. first...
A challenging decision exists as whether to abandon or remove noninfectious superfluous leads during lead revisions cardiac implantable electronic device (CIED) upgrades. There is insufficient data in the Asian population guide making.This study investigated safety and efficacy of transvenous extractions (TLEs) a high-volume Japanese center. Among total 341 patients who underwent CIED upgrades between 2008 2018, 53 (16%) TLEs were analyzed.Indications for TLE vascular issues (60%), recalled...
Management of pacemaker (PM) infections among advanced aged patients possesses particular clinical challenges due to higher rates concurrent cardiovascular disease and medical comorbidities. Novel leadless cardiac pacemakers (LCPs) may provide new opportunities for better management options in this population, however, there is limited data especially Asian populations guide the decision making.We reviewed 11 octogenarians (median age: 86 [minimum 82-maximum 90] years; male: 73%; median body...
This study sought to evaluate the prognostic value of time interval from left ventricular (LV) pacing earliest onset QRS complex (S-QRS) for long-term clinical outcomes in patients who underwent cardiac resynchronization therapy (CRT).The electrical latency during LV evaluated by S-QRS is associated with local tissue property, and ≥37 ms has been previously proposed as an independent predictor mechanical response CRT.This included 82 consecutive heart failure reduced ejection fraction (≤35%)...
Background: The association between the T-peak to T-end interval (Tp-e) and ventricular arrhythmia (VA) events in cardiac sarcoidosis (CS) is unknown. purpose of this study was investigate whether Tp-e associated with VA CS patients implantable cardioverter defibrillators (ICDs) or resynchronization therapy (CRT-Ds).
The long-term relationship between fracture-prone implantable cardioverter-defibrillator (ICD) leads and poor prognosis remains unclear in Japanese patients.
Transvenous lead extraction has been possible since the 1980s. However, complications during extraction, such as distal end fragment of remaining in myocardium or venous system and injury to veins heart, have reported.The purpose this study was examine our method for complete removal a separated lead, long-term implanted devices is difficult using standard methods may require additional procedures. The leads with inner conductor coil tip from outer insulation, coil, proximal ring electrode...
The HeartLogic multisensor algorithm™ (Boston Scientific) calculates the score based on heart sounds, nighttime rate, thoracic impedance, respiratory and patient activity level. MultiSENSE study showed that algorithm had a high negative predictive value good sensitivity for failure (HF) events.1 However, there were unexplained alerts. alert state was shown to be associated with atrial fibrillation occurrence.2 We hypothesized scores would elevated in ventricular arrhythmia (VA) events....
Abstract Background Acute pulmonary vein reconnection (PVR) is associated with long procedure times and large radiofrequency (RF) energy delivery during isolation (PVI). Although the efficacy of high‐power PVI (HP‐PVI) has been recently established, determinants acute PVR following HP‐PVI remain unclear. Methods We evaluated data on 62 patients paroxysmal atrial fibrillation undergoing unipolar signal modification (USM)‐guided HP‐PVI. A 50‐W RF wave was applied for 3‐5 seconds after USM. In...
Background:The number of patients undergoing cardiac resynchronization therapy has increased. Consequently, there is increased frequency in the removal and reimplantation coronary venous (CV) leads due to infection or malfunction.
