INTRODUCTION: Cardiac resynchronization using a left ventricular (LV) epicardial lead placed in the coronary sinus is now routinely used in management of heart failure patients. LV endocardial pacing is an alternative when this is not feasible, with outcomes data sparse. OBJECTIVE: To review the available evidence on the efficacy and safety of endocardial LV pacing via meta-analysis. METHODS: EMBASE, MEDLINE and COCHRANE databases with the search term "endocardial biventricular pacing" or "endocardial cardiac resynchronization" or "left ventricular endocardial" or "endocardial left ventricular"...

BACKGROUND: Electrical synchronization is likely improved by cardiac resynchronization therapy (CRT), but is difficult to quantify with 12-lead ECG. We aimed to quantify changes in electrical synchrony and potential for optimization with CRT using a body-surface activation mapping (BSAM) system. METHODS: Standard deviation of activation times (SDAT) was calculated in 94 patients using BSAM at baseline CRT (CRTbl), native, and different CRT configurations. RESULTS: SDAT decreased 20% from native to CRTbl (p<0...

INTRODUCTION: The bidirectional Glenn operation for congenital heart disease produces anatomical constraints to conventional transvenous pacemaker implantation. An iliac approach, although not previously described in this population, is potentially a preferable alternative to a thoracotomy for epicardial pacing. METHODS AND RESULTS: A single-center retrospective review was performed for all patients that underwent transvenous pacemaker implantation following the bidirectional Glenn operation with partial biventricular repair...

OBJECTIVES: Patients with decreased left ventricular function undergoing cardiac surgery have a greater chance of difficult weaning from cardiopulmonary bypass and a poorer clinical outcome. Directly after weaning, interventricular dyssynchrony, paradoxical septal motion, and even temporary bundle-branch block might be observed. In this study, the authors measured arterial dP/dtmax, mean arterial pressure (MAP), and cardiac index using transpulmonary thermodilution, pulse contour analysis, and femoral artery catheter and compared the effects between right ventricular (A-RV) and biventricular (A-BiV) pacing on these parameters...

BACKGOUND: Multipoint left ventricular (LV) pacing (MultiPoint™ Pacing [MPP], Abbott) improves the response rate to cardiac resynchronization therapy (CRT). We evaluated the feasibility of non-invasive radial artery tonometry (RAT) to characterize arterial pressure morphology changes (pre-ejection period [PEP] and ejection duration [ED]) between conventional CRT and MPP pacing interventions. METHODS: Patients with a MPP-enabled CRT device (Quadra Assura MP™, Abbott) underwent non-invasive RAT assessment (SphygmoCor CVMS, AtCor Medical Inc...

Introduction: Coronary sinus (CS) is the largest vein draining the blood from heart. It is a muscular tube of about 2 cm to 3 cm length and 1 cm in caliber. It has become a clinically important structure through its role in providing access for different cardiac procedures viz., biventricular pacing, arrhythmia ablation and for deployment of an array of cardiac devices. Aim: To study the location, shape, length and width of CS including its left atrial muscular coverage in 50 cadaveric hearts...

BACKGROUND: Clinical studies demonstrate that up to 40% of patients do not respond to cardiac resynchronization therapy (CRT), thus, appropriate patient selection is critical to the success of CRT in heart failure. OBJECTIVE: Evaluation of mortality predictors and response to CRT in the Brazilian scenario. METHODS: Retrospective cohort study including patients submitted to CRT in a tertiary hospital in southern Brazil from 2008 to 2014. Survival was assessed through a database of the State Department of Health (RS)...

BACKGROUND: Patients with atrial fibrillation (AF) often undergo AV junction ablation (AVJA) and pacemaker implantation. Right ventricular (RV) pacing contributes to increased risk of heart failure (HF), which may be mitigated by biventricular pacing. We sought to determine the impact of AVJA concurrent with RV versus biventricular pacemaker implantation on AF and HF hospitalizations. METHODS AND RESULTS: The MarketScan Commercial and Medicare Supplemental claims database was used to select 18- to 100-year-old patients with AF with pacemaker implantation...

A patient presented with symptoms of decompensated heart failure 2 months after percutaneous mitral valve (MV) repair. Echocardiography demonstrated impaired left ventricular function with elevated MV pressure gradients and pulmonary pressures during rapid atrial fibrillation. Heart rate control was achieved by implantation of a biventricular pacemaker with subsequent His-bundle ablation because atrial fibrillation was refractory to medical treatment. During biventricular pacing at different rates (50-110 b...

Electro-anatomical maps (EAMs) are commonly acquired in clinical routine for guiding ablation therapies. They provide voltage and activation time information on a 3-D anatomical mesh representation, making them useful for analyzing the electrical activation patterns in specific pathologies. However, the variability between the different acquisitions and anatomies hampers the comparison between different maps. This paper presents two contributions for the analysis of electrical patterns in EAM data from biventricular surfaces of cardiac chambers...

INTRODUCTION: Cardiac resynchronization therapy (CRT) or biventricular pacing (BIVP) has become a common procedure for the treatment of ventricular dyssynchrony in patients with heart failure, particularly in those with bundle branch block patterns (QRS durations >150ms) on the electrocardiogram (ECG). However, a large group of non-responders are made up of patients with dyssynchrony and QRS duration below 130ms. Recent studies have introduced permanent His bundle pacing as another method for achieving normalization of the QRS duration even in a majority of patients with right or left bundle branch block pattern on the ECG...

BACKGROUND: With increasing use of cardiac resynchronization therapy (CRT), treating physicians should be familiar with different electrocardiographic (ECG) patterns of left ventricular (LV) lead and biventricular (BiV) pacing. However, there are a few publications on ECG patterns during BiV pacing. PURPOSE: This study was sought to determine different ECG patterns in patients with BiV pacing. METHODS: Twelve-lead ECGs during BiV pacing (right ventricular leads at apex and LV leads in one of the lateral coronary veins) were analyzed in 181 consecutive patients (121 male; mean age, 62...

BACKGROUND: Current algorithms and device morphology templates have been proposed in current Implantable Cardioverter-Defibrillators (ICDs) to minimize inappropriate therapies (ITS), but this has not been completely successful. AIM: Assess the impact of a deliberate strategy of using an atrial lead implant with standardized parameters; based on all current ICD discriminators and technologies, on the burden of ITS. METHOD: A retrospective single-centre analysis of 250 patients with either dual chamber (DR) ICDs or biventricular ICDs (CRTDs) over a (41...

Aims: Left ventricular (LV) fusion pacing appears to be at least as beneficial as biventricular pacing in cardiac resynchronization therapy (CRT). Optimal LV fusion pacing critically requires adjusting the atrioventricular (AV)-delay to the delay between atrial pacing and intrinsic right ventricular (RV) activation (Ap-RV). We explored the use of electrogram (EGM)-based vectorloop (EGMV) derived from EGMs of implanted pacing leads to achieve optimal LV fusion pacing and to compare it with conventional approaches...

OBJECTIVE: Although heart failure (HF) is the leading cause of premature death in adult congenital heart disease (ACHD), little population-specific data exist. This study reports early experience from a dedicated, sub-specialty adult congenital heart disease-heart failure (ACHD-HF) clinic, aiming to identify risk factors for adverse outcome. METHODS: Between 2012 and 2015, 126 patients (57% male) attended the ACHD-HF clinic. Baseline and follow-up data were analysed and compared across 4 anatomical/physiological subgroups: cyanotic ACHD, Fontan circulation (1V), biventricular circulation with a subaortic right ventricle (2V-RV) and biventricular circulation with a subaortic left ventricle (2V-LV)...

BACKGROUND: In cardiac resynchronization therapy (CRT), quadripolar (QUAD) left ventricular (LV) leads are less prone to postoperative complications than non-QUAD leads. Some studies have suggested better clinical outcomes. METHODS AND RESULTS: Clinical events were assessed in 847 patients after CRT-pacing or CRT-defibrillation using either QUAD (n=287) or non-QUAD (n=560), programmed to single-site site LV pacing. Over a follow-up period of 3.2 years (median [interquartile range, 1...

Aims: A difficult cardiac resynchronization therapy (CRT) implantation scenario emerges when no lateral pacing option exists. The aim of this study was to explore the effect of biventricular pacing (BIVP) on vectorcardiographic parameters in patients with a non-lateral left ventricular (LV) lead position. We hypothesized that perimeter and area reduction for both the QRS complex and T-wave would predict acute CRT response. Methods and results: Twenty-six patients (14 ischaemic) with a mean age of 63 ± 10 years and standard CRT indication underwent device implantation with continuous LV pressure registration...
