Allostatic load modelling, lifestyle and cardiological risk factor: evidence for integrating patient profiling in the optimisation of pharmacological therapies during follow-ups in hospital setting - PLAY-UP cohort study protocol.

Introduction: The allostatic load (AL) is a framework for conceptualising the physiological multisystemic impact of prolonged exposure to stress and its related side effects on mental health.Stress due to AL can influence the development and outcomes of cardiovascular diseases. AL increases the risk of coronary and peripherical artery diseases.

Assessment of Esophageal Shifts during Catheter Ablation of Atrial Fibrillation Using Intracardiac Ultrasound Integrated with 3-Dimensional Electroanatomical Mapping System.

Atrioesophageal fistula is one of the most feared complications of radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) as it is associated with high mortality. Determining the esophagus location during RFCA might reduce the risk of esophageal injury. The present study aims to evaluate the feasibility of using intracardiac echocardiography integrated into a 3-dimensional electroanatomical mapping system (ICE/3D EAM) for the assessment of esophageal position and shifts in response to ablation.

Impact of preventive substrate catheter ablation on implantable cardioverter-defibrillator interventions in patients with ischaemic cardiomyopathy and infarct-related coronary chronic total occlusion.

Aims: Primary prevention patients with ischaemic cardiomyopathy and chronic total occlusion of an infarct-related coronary artery (CTO) are at a particularly high risk of implantable cardioverter-defibrillator (ICD) therapy occurrence. The trial was designed to evaluate the efficacy of preventive CTO-related substrate ablation strategy in ischaemic cardiomyopathy patients undergoing primary prevention ICD implantation.

Methods And Results: The PREVENTIVE VT study was a prospective, multicentre, randomized trial including ischaemic patients with ejection fraction ≤40%, no documented ventricular arrhythmias (VAs), and evidence of scar related to the coronary CTO.

Cognitive behavioral therapy for managing obesity in patients with chronic kidney disease: Study protocol for a randomized controlled trial.

Unlabelled: Obesity is one of the main risk factors for progression of chronic kidney disease (CKD). Weight loss interventions have limited efficacy in patients with pre-dialysis CKD. Our objective is to test the efficacy of a cognitive behavioral therapy program for obesity management in patients with CKD.

How Imaging Techniques Improve Ventricular Arrhythmia Ablation: A Multimodality-Based Approach.

Although implantable cardioverter defibrillators offer the best protection against sudden cardiac death, catheter ablation for ventricular arrhythmias (VAs) can modify or prevent this event from occurring. In order to achieve a successful ablation, the correct identification of the underlying arrhythmogenic substrate is mandatory to tailor the pre-procedural planning of an ablative procedure as appropriately as possible. We propose that several of the imaging modalities currently used could be merged, including echocardiography (also intracardiac), cardiac magnetic resonance, cardiac computed tomography, nuclear techniques, and electroanatomic mapping.

Intermittent ventricular pre-excitation in symptomatic adults: Always a marker of low risk?

Background: Intermittent ventricular pre-excitation was considered a low-risk marker for sudden death. However, to date, some studies do not exclude the existence of accessory pathways (APs) with high-risk intermittent antegrade conductive properties. According to current European Guidelines, high-risk features of APs are antegrade pathway conduction ≤250 ms in baseline or during the adrenergic stimulus, inducibility of atrioventricular reciprocating tachycardias (AVRT), inducibility of pre-excited atrial fibrillation (AF), and presence of multiple APs.

Ablation of residual potentials along the circumferential line reduces acute pulmonary vein reconnection.

Introduction: Acute pulmonary vein (PV) reconnection is frequently encountered in patients undergoing PV isolation (PVI) procedure for the treatment of atrial fibrillation. In this study, we investigated whether the identification and ablation of residual potentials (RPs), after the initial achievement of PVI, reduces acute PV reconnection rate.

Methods: Following PVI in 160 patients, mapping along the ablation line was performed to identify RPs, defined as bipolar amplitude ≥0.

Conventional fluoroscopy-guided versus zero-fluoroscopy catheter ablation of supraventricular tachycardias.

Purpose: The aim of this study was to evaluate the safety and efficacy of zero-fluoroscopy (ZF) catheter ablation (CA) for supraventricular tachycardias (SVT).

Methods: 584 consecutive patients referred to our institution for CA of SVT were analysed. Patients were categorised into two groups; zero-fluoroscopy (ZF) group and conventional fluoroscopy (CF) group.

Differences in activated clotting time and total unfractionated heparin dose during pulmonary vein isolation in patients on different anticoagulation therapy.

Background: Periprocedural pulmonary vein isolation (PVI) anticoagulation requires balancing between bleeding and thromboembolic risk. Intraprocedural anticoagulation is monitored by activated clotting time (ACT) with target value >300 s, and there are no guidelines specifying an initial unfractionated heparin (UFH) dose.

Methods: We aimed to assess differences in ACT values and UFH dosage during PVI in patients on different oral anticoagulants.

Biventricular versus His bundle pacing after atrioventricular node ablation in heart failure patients with narrow QRS.

His bundle pacing (HBP) is a physiological alternative to biventricular (BiV) pacing. We compared short-term results of both pacing approaches in symptomatic atrial fibrillation (AF) patients with moderately reduced left ventricular (LV) ejection fraction (EF ≥35% and <50%) and narrow QRS (≤120 ms) who underwent atrioventricular node ablation (AVNA). Thirty consecutive AF patients who received BiV pacing or HBP in conjunction with AVNA between May 2015 and January 2020 were retrospectively assessed.

Treatment of left-sided extension of AV node: A valuable integration of advance imaging modalities and cryoablation.

We present a case of successful cryoablation of the left extension of the atrioventricular (AV) node for treatment of a recurrent atrioventricular nodal reentry tachycardia without the use of fluoroscopy. Three-dimensional electroanatomic mapping system and intracardiac echocardiography were used to navigate catheters in the heart and position them according to anatomical landmarks. Due to the nature of cryoablation lesion formation, lesions were able to be applied safely in right atrium, as well as in left atrium, without damaging AV node or bundle of His.

Fluoroless radiofrequency and cryo-ablation of atrioventricular nodal reentry tachycardia in adults and children: a single-center experience.

Background: Radiofrequency ablation (RFA) and cryo-ablation (CRA) have been traditionally performed with fluoroscopy which exposes patients and medical staff to the potential harmful effects of the X-ray. Therefore, we aimed to assess the feasibility, safety, and effectiveness of RFA and CRA of atrioventricular nodal reentry tachycardia (AVNRT) guided by the three-dimensional (3D) electro-anatomical mapping (EAM) system without the use of fluoroscopy.

Methods: We analyzed 168 consecutive patients with AVNRT, 62 of whom were under 19 years of age (128 in RFA (age 34.

Intra-cardiac ultrasound guided approach for catheter ablation of typical right free wall accessory pathways.

Background: Right free wall accessory pathways (AP) are difficult to treat with catheter ablation as ablation catheter (AC) instability at the tricuspid annulus often precludes successful procedure. The aim of our study was to test a novel intra-cardiac echocardiography (ICE) guided technique for AC placement. Feasibility and success rates were observed.

Combined use of electro-anatomic mapping system and intracardiac echocardiography to achieve zero-fluoroscopy catheter ablation for treatment of paroxysmal atrial fibrillation: a single centre experience.

Fluoroscopy is the principal imaging method for catheter ablation (CA) of atrial fibrillation (AF). However, radiation exposure carries potential health risk to patients and operators alike. Our aim was to study safety and efficacy of zero-fluoroscopy CA of paroxysmal AF with a combined use of electroanatomic mapping system (EAM) and intracardiac echocardiography (ICE).

Radiofrequency catheter ablation versus balloon cryoablation of atrial fibrillation: markers of myocardial damage, inflammation, and thrombogenesis.

Background: Evidence from animal and human studies suggests that cryoablation might be associated with a lesser inflammatory response and activation of coagulation compared with radiofrequency ablation. The study was aimed at comparing the effect of cryoballoon and radiofrequency catheter ablation of paroxysmal atrial fibrillation on markers of myocardial damage, inflammation, and activation of coagulation.

Methods: Forty-one patients received either cryoballoon (n = 23) or radiofrequency (n = 18) ablation of atrial fibrillation.

Improvement of Atrial and Ventricular Remodeling with Low Atrial Fibrillation Burden after Hybrid Ablation of Persistent Atrial Fibrillation.

Background: An endoscopic transdiaphragmatic epicardial radiofrequency ablation procedure combined with percutaneous endocardial radiofrequency ablation--a hybrid procedure--is a potentially curative treatment option for patients with persistent atrial fibrillation (AF). Long-term effects of arrhythmia elimination on atrial and ventricular remodeling are not completely understood. Therefore, the aim of our study was to quantify echocardiographic structural and functional changes of the left atrium (LA) and left ventricle (LV) following a hybrid procedure.

Hemoglobin A1c is a better predictor of prognosis following the non-ST elevation acute coronary syndrome than fasting and admission glucose.

Background: Glucometabolic status is an important predictor of prognosis in patients with acute myocardial infarction. Both plasma glucose levels and glycosylated hemoglobin A1c (HbA1c) were implicated as predictors of prognosis. However, previous data yielded conflicting results.

Low rate of atrial fibrillation recurrence verified by implantable loop recorder monitoring following a convergent epicardial and endocardial ablation of atrial fibrillation.

Objective: Evaluate long-term outcomes in patients undergoing the Convergent procedure (CP) for the treatment of atrial fibrillation (AF).

Background: The CP provides a multidisciplinary approach, combining endoscopic creation of epicardial linear lesions followed by endocardial mapping and ablation and targets persistent and longstanding persistent AF patients who are at increased risk of heart failure, stroke, and mortality.

Methods: Outcomes from a prospective nonrandomized study were recorded for consecutive patients by interrogation of implanted Reveal monitors.

Simultaneous catheter and epicardial ablations enable a comprehensive atrial fibrillation procedure.

Objective: Transmural and contiguous ablations and a comprehensive lesion pattern are difficult to create from the surface of a beating heart but are critical to the successful treatment of persistent, isolated atrial fibrillation. A codisciplinary simultaneous epicardial (surgical) and endocardial (catheter) procedure (Convergent procedure) addresses these issues.

Methods: Patients with symptomatic atrial fibrillation who failed medical treatment were evaluated.

Importance of evaluating conduction block in radiofrequency ablation for atrial fibrillation.

Objective: Atrial fibrillation (AF) is the most frequently diagnosed cardiac arrhythmia. Anti-arrhythmic drugs may be used to suppress ectopic foci and interrupt reentry circuits, but are often insufficient to treat recurrent AF and have a number of adverse effects. Alternative therapies, such as catheter and surgical ablation, have been explored.

Citrate anticoagulation during post-dilution hemodiafiltration with a high cut-off (Theralite) membrane.

Citrate anticoagulation has not yet been described for hemodiafiltration (HDF) with high cut-off (HCO) membranes, which can be used in the treatment of cast nephropathy secondary to multiple myeloma. A 57-year-old male patient with multiple myeloma and acute renal failure was treated with HDF using a HCO membrane (Theralite) each or every other day. Due to thrombocytopenia, citrate anticoagulation was done for the first 7 h, and anticoagulant-free HDF was performed for the last hour to avoid citrate accumulation.

Electrophysiology of anterograde right-atrial and left-atrial inputs to the atrioventricular node in patients with atrioventricular nodal re-entrant tachycardia.

Aims: To study anterograde atrioventricular (A-V) nodal electrophysiological properties through the right-atrial (Ri) and left-atrial inputs (Li) under the pharmacological autonomic blockade (AUB) in patients with slow-fast A-V nodal re-entrant tachycardia (AVNRT) and in controls.

Methods And Results: Twenty-nine patients with slow-fast AVNRT and 15 control subjects were included. Programmed stimulation with single extrastimulus was performed from the right atrial appendage to test the Ri, and from the posterolateral coronary sinus to test the Li.
