BACKGROUND: Incomplete surgical left atrial appendage occlusion (S-LAAO) with a narrow neck has been shown to predict an increased rate of embolic stroke. Patients with a previously attempted S-LAAO were systematically excluded from all clinical trials of LAA closure devices. OBJECTIVE: Evaluate the feasibility of Watchman LAA device closure for patients referred with chronically incomplete S-LAAO. METHODS: Prospective single arm feasibility cohort of Watchman LAA closure following incomplete S-LAAO...

BACKGROUND: Uninterrupted anticoagulation is important for patients at high risk of thromboembolism. Bridging with heparin/lovenox increases the risk of hematoma and infection. There is no published data on the feasibility of transvenous lead extraction (TLE) during uninterrupted anticoagulation. OBJECTIVE: This study aims to examine the feasibility and safety of TLE during uninterrupted warfarin therapy with therapeutic international normalized ratio (INR). METHODS: We performed a retrospective study of patients undergoing TLE while on uninterrupted warfarin therapy with INR > 2...

BACKGROUND: Irreversible electroporation (IRE) is a novel tumor ablative therapy technique, using electric fields to induce apoptosis in target tissues. It is unclear whether these electric pulses of high field strength can cause cardiac damage and/or ablation induced arrhythmias. OBJECTIVE: To systematically evaluate the safety of ECG gated IRE in regards to cardiac side effects. METHODS: In all patients 12-lead electrocardiogram (ECG), signal-averaged ECG (SAECG) recordings were performed before and after IRE and 24-hour Holter recording on the day of the IRE procedure...

BACKGROUND: Atrial fibrillation (AF) ablation is associated with a substantial risk of silent cerebral events/lesions (SCEs/SCLs) detected on magnetic resonance imaging (MRI). OBJECTIVE: We investigated the factors associated with the incidence of SCEs/SCLs during second-generation cryoballoon ablation. METHODS: Two hundred fifty-six AF patients underwent a brain MRI 1 day after a pulmonary vein (PV) isolation using second-generation cryoballoons with a single 28-mm balloon and short freeze strategy...

BACKGROUND: Functional mitral regurgitation (FMR) and atrial fibrillation (AF) are frequent heart failure (HF) complications. Cardiac resynchronization therapy (CRT) can improve FMR; however, little is known about the influence of AF on FMR improvement. OBJECTIVE: To investigate the mechanisms and impact of baseline AF on FMR improvement after CRT. METHODS: CRT recipients with HF, AF or sinus rhythm (SR) at baseline with moderate or severe FMR, were included from an ongoing registry...

BACKGROUND: Rare genetic variants in TNNI3K encoding Troponin-I interacting kinase have been linked to a distinct syndrome consisting primarily of supraventricular tachycardias and variably expressed conduction disturbance and dilated cardiomyopathy in two families. OBJECTIVE: We aimed to identify new genetic variants associated with inherited supraventricular tachycardias, cardiac conduction disease, and cardiomyopathy. METHODS: We conducted next generation sequencing in 3 independent multi-generational families with atrial/junctional tachycardia with or without conduction disturbance, dilated cardiomyopathy and sudden death...

BACKGROUND: Second-generation cryoballoon (CB2)-based pulmonary vein isolation (PVI) has demonstrated encouraging clinical results in the treatment of paroxysmal (PAF) and persistent atrial fibrillation (PersAF). However rhythm follow-up after PVI is mainly based on Holter ECG of limited duration. OBJECTIVE: The aim of this study was to assess the real AF burden following CB2-based PVI in patients with implanted cardiac devices. METHODS: A total of 670 consecutive patients underwent CB2-based PVI in three EP centers...

BACKGROUND: Arrhythmias are common in the pediatric population. In patients unable to take oral medications or in need of acute therapy, options of intravenous (IV) anti-arrhythmics are limited. Recently IV sotalol has become readily available, but experience in children is limited. OBJECTIVE: To describe our initial experience with the use of IV sotalol in the pediatric population. METHODS: A retrospective study of all pediatric patients receiving IV sotalol was performed...

BACKGROUND: Chronic anticoagulation is recommended for atrial fibrillation (AF) patients with thromboembolic risk factors regardless of AF duration/frequency. Continuous rhythm assessment with pacemakers (PMs)/implantable cardioverter-defibrillators (ICDs) and use of direct-acting oral anticoagulants (DOACs) may allow anticoagulation only around AF episodes, reducing bleeding without increasing thromboembolic risk. OBJECTIVE: The purpose of this study was to evaluate the feasibility/safety of intermittent DOAC use guided by continuous remote AF monitoring via dual-chamber PMs or ICDs...

BACKGROUND: Several cardiovascular diseases exhibit seasonal variations, but data about cold temperature and risk of ischemic stroke in patients with atrial fibrillation (AF) are limited. OBJECTIVES: We aimed to investigate the risk of ischemic stroke in different seasons, testing the hypothesis that the cold weather season would increase the risk of stroke in AF. METHODS: This study used the "National Health Insurance Research Database" in Taiwan...

BACKGROUND: Pulmonary delivery of antiarrhythmic agents has the potential to increase targeted drug concentrations in pulmonary veins and left atrium rapidly to terminate atrial fibrillation (AF). OBJECTIVE: We evaluated the efficacy of flecainide administered via intratracheal instillation in terminating AF in a reliable preclinical model. METHODS: In 11 closed-chest anesthetized Yorkshire pigs, AF was induced by intrapericardial administration of acetylcholine (1 mL of 102...

BACKGROUND: The electrophysiological features and roles of persistent left superior vena cava (PLSVC) in supraventricular tachycardia (SVT) are not known. OBJECTIVE: To elucidate the electrophysiological features and roles of PLSVC in patients with SVT. METHODS: We included 37 patients (age: 43.5 ± 17.1 years; men: 35.1%) with PLSVC and 510 patients (age: 43.9 ± 18.8 years; men: 48.2%) without PLSVC who underwent an electrophysiological study for SVT...
