AbstractBackgroundLimited studies are available on the clinical significance of left ventricular lead polarity in patients undergoing cardiac resynchronization (CRT), with a recent study suggesting better outcomes with LV true bipolar pacing.ObjectivesWe aimed to determine whether True ‐Bipolar LV pacing is associated with reduced mortality in a large, real‐life CRT cohort, followed by remote monitoring.MethodsWe analyzed de ‐identified device data from CRT patients followed by the Boston Scientific LATITUDE remote monitoring database system. Patients with LV bipolar leads paced between the LV ring and LV tip were id...

Conclusions: This retrospective registry-based study provides a picture of CIED first implants in HCM patients in a Swedish tertiary university hospital. ICDs were the most commonly implanted devices, covering 59% of CIED implants. HCM patients receiving a pacemaker or an ICD had different epidemiological and clinical profiles.

ConclusionsInadequate programming (active LV sensing with T ‐wave protection) is the main cause of impaired resynchronization in devices with left ventricular sensing. In general, we recommend the deactivation of the LV T‐wave protection function.This article is protected by copyright. All rights reserved

CONCLUSIONS: Among HF patients with LVEF ≤ 35%, clinical factors including older age, CAD, and previous MI are associated with transmural LGE in the posterolateral wall, while CAD is associated with LGE. This data may have potential implications for planning ICD and CRT placement procedures. PMID: 32037500 [PubMed - as supplied by publisher]

McKelvieAbstractGlobally, there are ∼ 26 million people living with heart failure (HF), 50% of them with reduced ejection fraction, costing countries billions of dollars each year. Improvements in treatment of cardiovascular diseases, including advanced HF, have allowed an unprecedented number of patients to survive into old age. Despite these advances, patients with HF deteriorate and often require advanced therapies. As the proportion of elderly...

This study aimed to investigate eligibility, titration, and tolerability for Sac/Val in a real ‐world clinical setting.Methods and resultsThis retrospective cohort study consists of two parts. In Part 1 (eligibility study), all patients discharged from Sahlgrenska University Hospital due to HF were consecutively included during 1 year. Data from the patients' medical records were collected. Patients were adjudicated to be eligible based on European Society of Cardiology (ESC) criteria for angiotensin receptor neprilysin inhibitor (ARNI) with the exception of N ‐terminal (NT)‐proBNP levels. Patients who received
