Aims: Currently, there is limited data on prognostic indicators after insertion of percutaneous ventricular assist device (PVAD) in the treatment of cardiogenic shock (CS). This study evaluated the prognostic role of cardiac power output (CPO) ratio, defined as CPO at 24 h divided by early CPO (30 min to 2 h), in CS patients after PVAD.
Methods And Results: Consecutive CS patients from the QEH-PVAD Registry were followed up for survival at 90 days after PVAD.
Aims: Aveir VR performance and predictors for its pacing threshold (PCT) in a real-world cohort were investigated.
Methods: Electrical measurements at various stages of an Aveir VR implant were prospectively collected. Predictors for 3-month PCT were studied.
Background: Patients with heart failure and a non-left bundle branch block (non-LBBB) QRS pattern have a limited response to biventricular pacing (BVP).
Objective: A personalized cardiac resynchronization therapy (CRT) implantation approach guided by real-time electrocardiographic imaging (ECGi) was studied.
Methods: Twenty patients with left ventricular ejection fraction (LVEF) ≤ 35%, QRS duration ≥ 120 ms, and non-LBBB [13 (65%) with right bundle branch block and 7 (35%) with intraventricular conduction delay] were recruited.
Background: During slow pathway modification for atrioventricular nodal reentrant tachycardia, heart block may occur if ablation cannot be stopped in time in response to high risk electrogram features (HREF).
Objectives: To develop an automatic algorithm to monitor HREF and terminate ablation earlier than human reaction.
Methods: Digital electrogram data from 332 ablation runs from February 2020 to June 2022 were included.
Article Synopsis
- * Out of 113 patients treated, 45% had their AF successfully terminated, with some also showing improvements in areas like the right atrium (RA).
- * On average, 78% of patients remained free from AF after 24 months without needing antiarrhythmic medications, suggesting the method's effectiveness.
Objectives: This study investigated the prognosis of coronary microvascular disease (CMD) as determined by stress perfusion cardiac magnetic resonance (CMR) in patients with ischemic symptoms but without significant coronary artery disease (CAD).
Background: Patients with CMD have poorer prognosis with various cardiac diseases. The myocardial perfusion reserve index (MPRI) derived from noninvasive stress perfusion CMR has been established to diagnose microvascular angina with a threshold MPRI <1.
