PURPOSE: Recent studies suggest that atrial fibrillation (AF) is associated with increased cardiovascular risk and mortality including sudden cardiac death (SCD). According to the Cardiovascular Heath Study cohort, the incident rate of SCD was higher in the AF population (2.9 per 1000 per year) compared with non-AF controls (1.3 per 1000 per year). In this study, we performed a systematic review and meta-analysis to explore the association between AF and SCD. METHODS: We comprehensively searched the databases of MEDLINE and EMBASE from inception to January 2017...

PURPOSE: Coupling interval (CI) variability of premature ventricular contractions (PVCs) is influenced by the underlying arrhythmia mechanism. The aim of this study was to compare CI variability of PVCs in different myocardial disease entities, in order to gain insight into their arrhythmia mechanism. METHODS: Sixty-four patients with four underlying pathologies were included: idiopathic (n = 16), non-ischemic dilated cardiomyopathy (NIDCM) (n = 16), familial cardiomyopathy (PLN/LMNA) (n = 16), and post-MI (n = 16)-associated PVCs...

PURPOSE: The use of 3D mapping during cryoballoon pulmonary vein isolation (PVI) is optional with added cost but potential benefit in aiding vein identification, reducing fluoroscopy, and post-ablation testing. Data are limited evaluating procedural characteristics and outcomes in patients undergoing cryoballoon PVI with mapping vs. no mapping. In the present study, we compare procedural characteristics and recurrence-free rates in patients undergoing cryoballoon PVI among patients using CARTO®, NavX™, or no mapping system...

Christopher Reithmann, Michael Fiek
BACKGROUND: Ventricular arrhythmias (VAs) from the left ventricular outflow tract (LVOT) can have multiple exits exhibiting divergent ECG features. METHODS: In a series of 131 patients with VAs with LVOT origin, 10 patients presented with divergent QRS morphologies. Multisite endo- and epicardial mapping of different exit sites was performed. RESULTS: The earliest ventricular activity of 23 LVOT VAs in 10 patients was detected in the endocardium of the LV in 7 patients, the aortic sinuses of Valsalva (SoV) in 3 patients, the distal coronary sinus in 6 patients, the anterior interventricular vein in 3 patients, and the posterior right ventricular outflow tract (RVOT) in 4 patients...

BACKGROUND: Cardiac resynchronization therapy (CRT) is an effective treatment for heart failure (HF); however, a third of patients are non-responders. The development of quadripolar left ventricular (LV) lead was shown, mainly in single manufactures' registry, to improve LV remodeling and overall mortality. However, limited reports exist on the impact of quadripolar LV leads on HF hospitalization rates in real-life cohorts. We evaluated the clinical outcomes associated with quadripolar LV leads in a large nation-wide registry including all patients implanted with a cardiac resynchronization therapy with defibrillator (CRT-D)...

BACKGROUND: Atrial fibrillation (AF) commonly occurs in chronic kidney disease (CKD), occasioning adverse outcomes. Merging pulmonary vein isolation (PVI) and renal sympathetic denervation (RSD) may decrease the recurrence of AF in subjects with CKD and uncontrolled hypertension. We considered that RSD could reduce the recurrence of AF in patients with CKD by modulating sympathetic hyperactivity. We aimed to evaluate the impact of RSD or spironolactone 50 mg/day associated with PVI in reducing systolic blood pressure (BP), AF recurrence, and AF burden in patients with a history of paroxysmal AF and mild CKD...

PURPOSE: Transcatheter aortic valve replacement (TAVR) is an increasingly prevalent therapy in patients with severe symptomatic aortic stenosis. Conduction disturbances requiring permanent pacemaker (PPM) implantation are a known complication of TAVR. This study investigated the progression of cardiac conduction disease in the post-TAVR pacemaker population and identified predictors of post-TAVR right ventricular (RV) pacing dependence. METHODS: Prospectively collected echocardiographic, ECG, and PPM interrogation data of 262 consecutive patients who underwent TAVR with placement of a balloon-expandable valve at one institution from March 2012 to October 2016 were analyzed...

PURPOSE: Protected channels of surviving myocytes in late postinfarction ventricular scar predispose to ventricular tachycardia (VT). However, only a few patients develop VT spontaneously. We studied differences in electric remodeling and protected channels in late postinfarction patients with and without spontaneous VT. METHODS: Patients with ischemic cardiomyopathy (ICM) with recurrent sustained monomorphic VT (n = 22) were compared with stable ICM patients without spontaneous VT (control group; n = 5)...

PURPOSE: Since the Brazilian current legislation permits the reuse of single-use devices under a validated processing protocol, the main purpose of our study was to develop and validate a method for reusing non-irrigated electrophysiology catheter (EC). METHODS: Manual and mechanical processing by ultrasonic washer was associated with the use of enzymatic solution and hydrogen peroxide with a final rinse with filtered water. Validation of the cleaning process, as well as catheter integrity, was done by observing the ECs in stereoscopic microscope at ×60 magnification, followed by HemoCheck-S® (HCS) test to monitor the presence of residual blood on their surfaces...

PURPOSE: In some patients, both an electrophysiological examination (EPS) and a coronary angiography (CA) are necessary. It might be preferable to choose a combined approach of EPS and CA versus performing them consecutively. The purpose of this study is to evaluate the type and rate of adverse events between both approaches. METHODS: Patients were eligible if they underwent a CA and an EPS in a combined approach or in a time interval of at most 2 months. In all patients, clinical adverse events were recorded...

BACKGROUND: Implantable cardioverter defibrillators (ICD) are life-saving device therapy, and patients often carry devices for decades with interim pulse generator exchanges. Inappropriate shocks are associated with impaired quality of life and increased mortality, but available data on their incidence and etiology outside of clinical trials is limited and usually restricted to the lifespan of a singular device. We hypothesized that the incidence in clinical practice is underestimated and aimed this study to retrospectively assess the long-term incidence and etiology of inappropriate shocks in a real-world cohort of patients with multiple ICDs over a long follow-up period...

PURPOSE: Late adverse myocardial remodeling after acute myocardial infarction (AMI) is strongly associated with sudden cardiac death (SCD). Cardiac magnetic resonance (CMR) performed early after AMI can predict late remodeling and SCD risk with moderate accuracy. This study assessed the ability of CMR-measured circumferential strain (CS) to add incremental predictive information to late gadolinium enhancement (LGE). METHODS: Patients with an AMI and LVEF < 50% were screened for inclusion...

PURPOSE: Guidelines recommend that radiation exposure during AF catheter ablation procedures should be 'as low as reasonably achievable' (ALARA), particularly since many patients may have multiple procedures. Consequently, avoiding radiation exposure altogether must, if safe to do so, be the ultimate goal. The primary objective was to determine the feasibility and efficacy of fluoroscopy-free AF ablation compared to the fluoroscopy-assisted procedure. METHODS: Patients underwent AF ablation using commercially available technology with no routine pre-procedural imaging...

PURPOSE: Epicardial pulmonary vein isolation has become an increasingly used therapy for medically resistant atrial fibrillation. The purpose of the present study was therefore to evaluate if epicardial pulmonary vein isolation combined with ganglionated plexi ablation affects the size and mechanical function of the left atrium, and whether the effects are dependent on the extensiveness of the ablation applications. METHODS: A total of 42 patients underwent an echocardiographic examination prior to and 6 months after a minimal invasive epicardial pulmonary vein isolation procedure for the assessment of the effects on left atrial size and function...

PURPOSE: The effect of novel catheter ablation techniques for atrial fibrillation (AF) on the autonomic nervous system (ANS) is unclear. This study aimed to assess the ANS after three novel catheter ablation techniques for paroxysmal AF by evaluating heart rate variability (HRV) parameters using a 3-min electrocardiogram recording. METHODS: Two hundred and thirty-five patients who underwent catheter ablation for paroxysmal AF (119 in irrigated-tip, 51 in contact-force sensing-guided, and 65 patients in second-generation cryoballoon ablation) were included...

PURPOSE: Radiofrequency catheter ablation (RFCA) for electrical storm (ES) has become a widely used therapeutic method. Its effectiveness in comparison to other forms of ES treatment is however uncertain. METHODS: This single-centre retrospective study investigated the long-term clinical outcome after RFCA for ES and compared long-time effects of ablation to other forms of treatment. The study population consisted of 70 consecutive patients hospitalised between January 2010 and June 2015 due to ES...
