Leadless Pacemaker Implantation Across Percutaneous Tricuspid Valve Prothesis Implanted Via Valve-in-Valve Technique.

We present the case of an 82-year-old woman with history of bivalvular replacement (mitral mechanical prothesis and tricuspid bioprothesis) and subsequent tricuspid percutaneous valve-in-valve bioprothesis implantation. The patient developed an indication for pacemaker implantation. We describe the feasibility of leadless pacemaker implantation across the tricuspid prothesis when all other techniques fail.

Temporal association between drops in thoracic impedance and malignant ventricular arrhythmia: A longitudinal analysis of remote monitoring trends.

Introduction: Thoracic impedance (TI) drops measured by implantable cardioverter-defibrillators (ICDs) have been reported to correlate with ventricular tachycardia/fibrillation (VT/VF). The aim of our study was to assess the temporal association of decreasing TI trends with VT/VF episodes through a longitudinal analysis of daily remote monitoring data from ICDs and cardiac resynchronization therapy defibrillators (CRT-Ds).

Methods And Results: Retrospective data from 2384 patients were randomized 1:1 into a derivation or validation cohort.

Ventricular Arrhythmias and Implantable Cardioverter-Defibrillator Therapy in Women: A Propensity Score-Matched Analysis.

Background: Causes of sex differences in incidence of sustained ventricular arrhythmias (SVAs) are poorly understood.

Objectives: This study aims to investigate sex-specific risk of SVAs and device therapies by balancing sex groups in relation to several baseline characteristics with the propensity score (PS).

Methods: We used a large remote monitoring dataset from implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy defibrillators (CRT-Ds).

Atrial signal amplitude predicts atrial high-rate episodes in implantable cardioverter defibrillator patients: Insights from a large database of remote monitoring transmissions.

Background: Parameters measured during implantable cardioverter defibrillator (ICD) implant also depend on bioelectrical properties of the myocardium. We aimed to explore their potential association with clinical outcomes in patients with single/dual-chamber ICD and cardiac resynchronization therapy defibrillator (CRT-D).

Methods: In the framework of the Home Monitoring Expert Alliance, baseline electrical parameters for all implanted leads were compared by the occurrence of all-cause mortality, adjudicated ventricular arrhythmia (VA), and atrial high-rate episode lasting ≥24 hours (24 h AHRE).

Rate-responsive pacing and atrial high rate episodes in cardiac resynchronization therapy patients: Is low heart rate the key?

Background: The role of atrial rate-responsive (RR) pacing in cardiac resynchronization therapy (CRT) is unclear due to the favorable effect of rate lowering in systolic heart failure. Atrial high rate episodes (AHREs) in CRT recipients are particularly worrisome since they cause loss of CRT, beyond representing a stroke risk factor.

Hypothesis: The presence of an association between RR and the incidence of AHREs.

Appropriate implantable cardioverter-defibrillator interventions in cardiac resynchronization therapy-defibrillator (CRT-D) patients undergoing device replacement: time to downgrade from CRT-D to CRT-pacemaker? Insights from real-world clinical practice in the DECODE CRT-D analysis.

Aim: Ventricular tachycardia (VT)/ventricular fibrillation (VF) occurrence after cardiac resynchronization therapy-defibrillator (CRT-D) replacement is unknown; hence, there is no practical guideline to recommend either CRT-D or CRT-pacemaker at the time of device replacement. We observed the 1-year VT/VF occurrence after CRT-D replacement in a subanalysis of the Detect Long-term Complications after ICD Replacement (DECODE) registry.

Methods And Results: A total of 332 consecutive patients who had undergone CRT-D replacement from 2013 to 2015 were enrolled in 36 Italian centres.

Manufacturer change and risk of system-related complications after implantable cardioverter defibrillator replacement: physicians' survey and data from the Detect Long-term Complications After Implantable Cardioverter Defibrillator Replacement Registry.

Aims: Some barriers seem to exist in changing implantable cardioverter defibrillator (ICD) manufacturer at the time of device replacement. We sought to understand the obstacles to changing ICD manufacturer within the cohort of patients enrolled in the Detect Long-term Complications After ICD Replacement Registry.

Methods: We analyzed 784 consecutive ICD/cardiac resynchronization therapy defibrillator (CRT-D) device replacements within a 1.

[Heart failure: epidemiology, costs and healthcare programs in Italy].

Epidemiological data show an even greater prevalence of heart failure in the general population, in particular in elderly people, both in Italy and the other European countries. Patients admitted to hospital because of heart failure are commonly complex patients with relevant comorbidities and frequent readmissions. Hospital care accounts largely for the costs due to heart failure, whereas expenditure for therapies (drugs, devices and surgery) is less significant; non-medical and social costs represent also a relevant part of total costs.
