Aveir VR real-world performance and chronic pacing threshold prediction using mapping and fixation electrical data.

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.

Personalized cardiac resynchronization therapy guided by real-time electrocardiographic imaging for patients with non-left bundle branch block.

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.

Prevention of hepatitis B virus reactivation in patients with hematological malignancies and resolved hepatitis B virus infection: a systematic review and meta-analysis.

Objective: Patients with resolved hepatitis B virus (HBV) infection are at risk of HBV reactivation during treatment for hematological malignancies. We conducted a systematic review and meta-analysis of the data on the efficacy of antiviral prophylaxis for the prevention of HBV reactivation in this group of patients.

Methods: We conducted a systemic literature search of PubMed including MEDLINE and EMBASE databases to 31 January 2019 to identify studies published in English comparing antiviral prophylaxis with no prophylaxis for HBV reactivation in patients treated for hematological malignancies.
