Background: Left bundle branch (LBBP) and His-bundle pacing (HBP) provide physiological ventricular activation.
Objectives: This study investigated differences in feasibility, device performance, and clinical outcomes between LBBP and HBP.
Methods: Consecutive patients with LBBP and HBP from 2018 to 2021 in 2 centers were prospectively studied.
Background: More than half of patients with embolic stroke of undetermined source (ESUS) suffer from recurrent ischaemic stroke, despite the absence of atrial fibrillation (AF) on invasive cardiac monitoring (ICM). This study investigated the predictors and prognosis of recurrent stroke in ESUS without AF on ICM.
Method: This prospective study included patients with ESUS at two tertiary hospitals from 2015 to 2021 who underwent comprehensive neurological imaging, transthoracic echocardiography, and inpatient continuous electrographic monitoring for ≥48 hours prior to ICM for definitive exclusion of AF.
Conduction system versus biventricular pacing in heart failure with non-left bundle branch block.
J Cardiovasc Electrophysiol
April 2023
Article Synopsis
- Cardiac resynchronization therapy (CRT) is less effective for heart failure patients with non-left bundle branch block (LBBB), but conduction system pacing (CSP) shows promise for these patients.
- In a study of 96 heart failure patients, CSP resulted in greater improvements in left ventricular function compared to biventricular pacing (BiV), with better echocardiographic responses and lower rates of hospitalizations and mortality.
- CSP is associated with increased chances of favorable outcomes, making it a potentially better option than BiV for treating non-LBBB heart failure patients.
Background: Conduction system pacing (CSP) provides more physiological ventricular activation than right ventricular pacing (RVP).
Objectives: This study evaluated the differences in clinical outcomes in patients receiving CSP and RVP.
Methods: Consecutive patients with pacemakers implanted for bradycardia from 2016 to 2021 in 2 centers were prospectively followed for the primary composite outcome of heart failure (HF) hospitalizations, upgrade to biventricular pacing, or all-cause mortality, stratified by ventricular pacing burden (Vp) .
Aims: This study aims to determine procedural characteristics, acute success rates, and medium-term outcomes of consecutive patients undergoing His bundle pacing (HBP); and learning curves of experienced electrophysiologists adopting HBP.
Methods And Results: Consecutive HBP patients at three hospitals were recruited. Clinical characteristics, acute procedural details, and medium-term outcomes were extracted from electronic medical records.
