Managing ventricular arrhythmias and implantable cardiac defibrillator shocks after left ventricular assist device implantation
AbstractContinuous flow left ventricular assist devices (CF-LVADs) have been shown to reduce mortality and morbidity in patients with advanced heart failure with reduced ejection fraction. However, ventricular arrhythmias (VA) are common, are mostly secondary to underlying myocardial scar, and have a higher incidence in patients with pre-LVAD VA. Sustained VA is well tolerated in the LVAD patient but can result in implantable defibrillator (ICD) shocks, right ventricular failure, hospitalizations, and reduced quality of life. There is limited data regarding best practices for the medical management of VA as well as the rol...

Cardiac resynchronization using fusion pacing during exercise
ConclusionFusion pacing is maintained during exercise without impairing exercise capacity compared with fixed AVD. However, using whichever algorithm gives the narrowest QRSd at rest is associated with a narrower QRSd during exercise, higher peak stroke volume, and improved cardiac efficiency.

Inappropriate shock incidence in patients with subcutaneous implantable cardioverter ‐defibrillators with concomitant cardiac implantable electronic devices: A single‐center cohort study
ConclusionThe incidence of inappropriate shock did not differ between patients with and without concomitant use of CIEDs, suggesting that S-ICDs could potentially be combined with other CIEDs without increasing the number of inappropriate shocks. Further studies are warranted to confirm the safety and feasibility of concomitant use of S-ICDs and CIEDs. (Source: Pacing and Clinical Electrophysiology : PACE)

Sleep-disordered breathing and cardiovascular disease: who and why to test and how to intervene?
Sleep-disordered breathing (SDB) is common in individuals with established cardiovascular disease (CVD), particularly those with heart failure (HF). There are two main types of SDB, central sleep apnoea (CSA) and obstructive sleep apnoea (OSA) which frequently overlap as mixed SDB. Investigating for SDB could be considered in patients with excessive daytime sleepiness, male sex, high body mass index, low ejection fraction, atrial fibrillation (AF), in patients with no dipping blood pressure pattern, recurrent paroxysms of nocturnal dyspnoea or when an apnoea is witnessed. Excessive daytime sleepiness is less likely to be r...

Therapeutic inertia in rhythm control strategies in hospitalized patients with fibrillation: Insights from Hellenic Cardiorenal Morbidity Snapshot (HECMOS) study
CONCLUSION: High prevalence of persistent AF was detected in hospitalized patients, with heart failure being the leading cause of admission and main co-morbidity. Rhythm control strategies are notably underused, along with CRT-D implantation in patients with AF and heart failure.PMID:37979719 | DOI:10.1016/j.jjcc.2023.11.004 (Source: Journal of Cardiology)

Risk of Atrial Fibrillation and Adverse Outcomes in Patients With Cardiac Implantable Electronic Devices
CONCLUSIONS: A substantial proportion of patients implanted CIED developed newly diagnosed AF. Incident AF was associated with a higher risk of adverse events. The importance of awareness, early detection, and appropriate management of AF in patients with CIED should be emphasized.PMID:37973974 | DOI:10.4070/kcj.2023.0084 (Source: Korean Circulation Journal)
