The value of QRS onset of the outflow tract PVC in V1 and V2 leads recorded in fourth, third, and second intercostal spaces to differentiate main origins of premature ventricular contraction—A prospective cohort study

Health Science Reports, 2022
Background Electrocardiography (ECG) is now proposed as a simple and cost‐effective tool to determine the location of arrhythmias before ablation. We aimed to examine the value of the QRS onset of outflow tract PVC in V1 and V2 leads recorded in fourth ...

Ablation of Outflow Tract Arrhythmias in Patients With and Without Structural Heart Disease—A Comparative Analysis

Frontiers in Cardiovascular Medicine, 2022
IntroductionCatheter ablation of ventricular arrhythmias emerging from the ventricular outflow tracts and adjacent structures is very effective and considered almost curative in patients without structural heart disease (SHD).

Early Stroke Volume Variation After Transcatheter or Surgical Aortic Valve Replacement Predicts Clinical Outcomes in Low‐Flow Aortic Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Little is known about stroke volume index (SVi) change and its prognostic implication in patients with low‐flow aortic stenosis (AS) undergoing aortic valve replacement (AVR) and conflicting results are present in literature. The aim of this study was to evaluate the postoperative change in SVi and its impact on outcomes in patients
