BACKGROUND: Research on the correlation of serum bilirubin level with cardiac function as well as outcomes in heart failure patients with cardiac resynchronization therapy (CRT) has not yet been reported. The aim of this study was to analyze the relationship between change in serum bilirubin level and left ventricular reverse remodeling, and also to clarify the impact of bilirubin change on clinical outcomes in CRT patients. METHODS: We evaluated 105 consecutive patients who underwent CRT...

Use of cardiac implantable devices and catheter ablation is steadily increasing in Western countries following the positive results of clinical trials. Despite the advances in scientific knowledge, tools development, and techniques improvement we still have some grey area in the field of electrical therapies for the heart. In particular, several reports highlighted differences both in medical behaviour and procedural outcomes between female and male candidates. Women are referred later for catheter ablation of supraventricular arrhythmias, especially atrial fibrillation, leading to suboptimal results...

BACKGROUND: Although the majority of Class III congestive heart failure (HF) patients treated with cardiac resynchronization therapy (CRT) show a clinical benefit, up to 40% of patients do not respond to CRT. This paper reports the design of the MultiPoint Pacing (MPP) trial, a prospective, randomized, double-blind, controlled study to evaluate the safety and efficacy of CRT using MPP compared to standard biventricular (Bi-V) pacing. METHODS: A maximum of 506 patients with a standard CRT-D indication will be enrolled at up to 50 US centers...

PURPOSE: Cardiac resynchronization therapy (CRT) has been shown to improve left atrial function; however the effect on reverse electrical remodeling has been poorly evaluated. We hypothesized that CRT might induce reverse atrial electrical remodeling manifesting in the surface ECG as a shortening in P-wave duration. METHODS: Patients with CRT and more than 92% biventricular pacing at minimum follow-up of 1 year were included in the analysis. Those with prior history of atrial fibrillation (AF) were excluded...

- Cardiac resynchronisation therapy (CRT) is a treatment for patients with impaired cardiac pump function (left ventricular ejection fraction ≤ 35%) and a wide QRS complex who, despite maximum tolerated medical therapy, remain symptomatic.- In addition to reducing symptoms, CRT can reduce hospital admissions and improve survival.- Selection of patients for CRT remains difficult. Despite the fact that predicting and influencing success of CRT has improved, ~30% of patients do not respond to the therapy.- Optimizing therapy and follow-up of patients after implantation requires a multidisciplinary approach tailored to the individual patient...

BACKGROUND: Some cardiac implantable electronic device (CIED) implantation procedures require the use of X-rays, which is reflected by such parameters as total fluoroscopy time (TFT) and dose-area product (DAP - defined as the absorbed dose multiplied by the area irradiated). MATERIAL AND METHODS: This retrospective study evaluated 522 CIED implantation (424 de novo and 98 device upgrade and new lead placement) procedures in 176 women and 346 men (mean age 75±11 years) over the period 2012-2015...

BACKGROUND: Among patients with implantable defibrillators (ICD), use of remote patient monitoring (RPM) is associated with lower risk of death and rehospitalization. Standard ICD RPM can be supplemented with weight and blood pressure data. It is not known whether standard RPM plus routine weight and blood pressure transmission (RPM+) is associated with better outcomes. METHODS AND RESULTS: RPM+ patients (n=4106) were compared with patients who only transmitted standard ICD RPM data (n=14 183)...

BACKGROUND: The currently proposed criteria for identifying patients who would benefit from cardiac resynchronization therapy (CRT) still need to be optimized. A multi-scale heart simulation capable of reproducing the electrophysiology and mechanics of a beating heart may help resolve this problem. The objective of this retrospective study was to test the capability of patient-specific simulation models to reproduce the response to CRT by applying the latest multi-scale heart simulation technology...

AbstractChagas disease (CD), with associated conduction abnormalities, is a common indication for pacemaker implantation in Latin America. The prevalence of CD in Latin American immigrants with pacemakers residing in the United States has never been studied. This single-center cross-sectional study included pacemaker patients who were aged 18 years or more with a previous residence in Latin America for at least 6 months. Patients with an implantable cardioverter-defibrillator, cardiac resynchronization therapy, or iatrogenic and/or congenital heart block were excluded...

BACKGROUND: Flow entering the left ventricle is reversed toward the outflow tract through rotating reversal flow around the mitral valve. This was thought to facilitate early ejection, but had not been proved to date. We hypothesized that perfect coupling between reversal and ejection flow would occur at optimal atrioventricular delay (AVD), contributing to its hemodynamic superiority, and evaluated its applicability for AVD optimization. METHODS AND RESULTS: Forty consecutive patients with cardiac resynchronization therapy underwent intracardiac flow analysis and AVD optimization...

Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown...

BACKGROUND: Data regarding cardiac resynchronization therapy (CRT) in patients with multiple comorbidities are limited. OBJECTIVES: This study evaluated the association of multiple comorbidities with the benefits of CRT over implantable cardioverter-defibrillator (ICD) alone. METHODS: We examined 1,214 MADIT-CRT (Multicenter Automatic Defibrillator Implantation Trial with Cardiac Resynchronization Therapy) study patients with left bundle branch block (LBBB) and 0, 1, 2, or ≥3 comorbidities, including renal dysfunction, hypertension (HTN), diabetes, coronary artery disease, history of atrial arrhythmias, history of ventricular arrhythmias, current smoking, and cerebrovascular accident...

OBJECTIVE: To evaluate left univentricular (LUV) pacing for cardiac resynchronization therapy (CRT) using a rate-adaptive atrioventricular delay (RAAVD) algorithm to track physiological atrioventricular delay (AVD). METHODS: A total of 72 patients with congestive heart failure (CHF) were randomized to RAAVD LUV pacing versus standard biventricular (BiV) pacing in a 1: 1 ratio. Echocardiography was used to optimize AVD for both groups. The effects of sequential BiV pacing and LUV pacing with optimized A-V (right atrio-LV) delay using an RAAVD algorithm were compared...

BACKGROUND: Whether outcomes differ between sexes following treatment with pacemakers (PM), implantable cardioverter defibrillators, and cardiac resynchronization therapy (CRT) devices is unclear. METHODS AND RESULTS: Consecutive US patients with newly implanted PM, implantable cardioverter defibrillators, and CRT devices from a large remote monitoring database between 2008 and 2011 were included in this observational cohort study. Sex-specific all-cause survival postimplant was compared within each device type using a multivariable Cox proportional hazards model, stratified on age and adjusted for remote monitoring utilization and ZIP-based socioeconomic variables...
