[Management of postoperative arrhythmias in the tetralogy of Fallot: a literature review].

Tetralogy of Fallot (ToF) occurs in about 4 births/1000/year and represents about one tenth of all congenital heart diseases. Nowadays 86% of patients reach adulthood with corrective surgery. Before the 1980s, these patients were treated only with "surgical palliation", which consisted in the creation of a systemic to pulmonary artery shunt or a pulmonary valvulotomy, whereas after the introduction of extracorporeal circulation, corrective surgery is performed electively between 3 and 6 months of life.

Incidence and Predictors of Infections and All-Cause Death in Patients with Cardiac Implantable Electronic Devices: The Italian Nationwide RI-AIAC Registry.

Background: The incidence of infections associated with cardiac implantable electronic devices (CIEDs) and patient outcomes are not fully known.

Aim: To provide a contemporary assessment of the risk of CIEDs infection and associated clinical outcomes.

Methods: In Italy, 18 centres enrolled all consecutive patients undergoing a CIED procedure and entered a 12-months follow-up.

Estimate and reporting of longevity for cardiac implantable electronic devices: a proposal for standardized criteria.

Background: Cardiac implantable electronic devices (CIEDs) are widely used according to consensus guidelines in various patient categories. The longevity of CIED is a major determinant of the frequency with which patients require device replacement. Given the mismatch between the useful life of the devices and patient survival, device replacement is often needed.

Organization and procedures in contemporary catheter ablation centres: data from the 2018 Italian Catheter Ablation Registry.

Aims: This report describes the findings of the 2018 Italian Catheter Ablation Registry of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC).

Methods: The Italian Catheter Ablation Registry systematically collects data on the ablation procedures performed in Italy. Data collection was retrospective.

Mortality after cardioverter-defibrillator replacement: Results of the DECODE survival score index.

Background: Device replacement is the ideal time to reassess health care goals regarding continuing implantable cardioverter-defibrillator (ICD) therapy. Only few data are available on the decision making at this time.

Objectives: The goals of this study were to identify factors associated with poor prognosis at the time of ICD replacement and to develop a prognostic index able to stratify those patients at risk of dying early.

[Position paper of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC) on driving by patients with cardiac implantable electronic devices].

In patients with cardiac implantable electronic devices (CIEDs) (implantable cardioverter-defibrillators [ICDs] and pacemakers [PMs]), the potential risk of suddenly being unable to drive, and hence of causing road accidents, is higher than in the general population. In ICD patients, this risk stems from the possibility that an arrhythmic event leading to loss of consciousness may occur while driving. In PM patients, it may be the result of a device malfunction in a PM-dependent patient.

[The unmet needs of sudden cardiac death. The role of the wearable cardioverter defibrillator when the risk is transient or uncertain].

Sudden cardiac death is defined as a natural death due to termination of cardiac activity associated with loss of consciousness, spontaneous breathing and circulation. Nowadays, the prevention of sudden cardiac death represents a major issue and many areas of uncertainty are not met by current evidences. Among those, reliable tools for risk stratification are still lacking, as well as solution for patients in which the risk of sudden cardiac death is due to a transient or correctable condition.

Temporary transvenous cardiac pacing: a survey on current practice.

Background: Temporary transvenous cardiac pacing (TTCP) is a standard procedure in current practice, despite limited coverage in consensus guidelines. However, many authors reported several complications associated with TTCP, especially development of infections of cardiac implantable electronic devices (CIED). The aim of this survey was to provide a country-wide picture of current practice regarding TTCP.

[Quality and performance in cardiac pacing and electrophysiology. An update to the 2010 Italian Association of Arrhythmology and Cardiac Pacing (AIAC) - Italian Federation of Cardiology (IFC) Document 'Structure and functional organization of Arrhythmology'].

In the last decade the field of cardiac pacing and electrophysiology underwent major advancements thanks to both new ways of arrhythmia management and technological innovations. At the same time, the clinical competence and the procedural qualitative level of Cardiac Rhythm Centers have increased significantly. In 2010 an ad hoc Committee of the Italian Association of Arrhythmology and Cardiac Pacing (AIAC) and the Italian Federation of Cardiology (FIC) published a consensus document on the organization of Cardiac Rhythm Centers and on the standards of professional practice in pacing and electrophysiology in Italy.

Intrahospital organizational model of remote monitoring data sharing, for a global management of patients with cardiac implantable electronic devices: a document of the Italian Association of Arrhythmology and Cardiac Pacing.

: In recent years, the increasing number of patients with a cardiac implantable electronic device (CIED) has required different approaches in terms of the device's control and surveillance. It is increasingly difficult to keep the traditional in-office protocol device's control: we must think of a different organization dedicated to the activity of remote control and monitoring (RC/RM) of devices and patients.A CIED team structured with nurses, technicians and physicians should be organized inside the hospital, with the aim of CIED patients' managing and of creating a network between the various departments.

[ANMCO/SICI-GISE/SIC/SIECVI/SIRM Consensus document: Appropriateness of multimodality imaging in cardiovascular disease].

The complexity of cardiovascular diseases has led to an extensive use of technological instruments and the development of multimodality imaging. This extensive use of different cardiovascular imaging tests in the same patient has increased costs and waiting times.The concept of appropriateness has changed over time.

Methods: A questionnaire consisting of 24 questions on organizational aspects and on the peri-procedural management of anticoagulant therapies and antibiotic prophylaxis was sent via the Internet to 154 Italian arrhythmia centers.

Results: A total of 103 out of 154 centers completed the questionnaire (67% response rate).

Real-life outcome of implantable cardioverter-defibrillator and cardiac resynchronization defibrillator replacement/upgrade in a contemporary population: observations from the multicentre DECODE registry.

Aims: The benefit of prolonged implantable cardioverter-defibrillator (ICD)/cardiac resynchronization therapy defibrillator (CRT-D) therapy following device replacement is hindered by clinical and procedure-related adverse events (AEs). Adverse events rate is highest in more complex devices and at upgrades, as per the REPLACE registry experience, but is changing owing to the improvement in device technology and medical care. We aimed at understanding the extent and type of AEs in a contemporary Italian population.

Clinically oriented device programming in bradycardia patients: part 2 (atrioventricular blocks and neurally mediated syncope). Proposals from AIAC (Italian Association of Arrhythmology and Cardiac Pacing).

: The purpose of this two-part consensus document is to provide specific suggestions (based on an extensive literature review) on appropriate pacemaker setting in relation to patients' clinical features. In part 2, criteria for pacemaker choice and programming in atrioventricular blocks and neurally mediate syncope are proposed. The atrioventricular blocks can be paroxysmal or persistent, isolated or associated with sinus node disease.

Clinically oriented device programming in bradycardia patients: part 1 (sinus node disease). Proposals from AIAC (Italian Association of Arrhythmology and Cardiac Pacing).

: Modern pacemakers have an increasing number of programable parameters and specific algorithms designed to optimize pacing therapy in relation to the individual characteristics of patients. When choosing the most appropriate pacemaker type and programing, the following variables must be taken into account: the type of bradyarrhythmia at the time of pacemaker implantation; the cardiac chamber requiring pacing, and the percentage of pacing actually needed to correct the rhythm disorder; the possible association of multiple rhythm disturbances and conduction diseases; the evolution of conduction disorders during follow-up. The goals of device programing are to preserve or restore the heart rate response to metabolic and hemodynamic demands; to maintain physiological conduction; to maximize device longevity; to detect, prevent, and treat atrial arrhythmia.

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.

Antiarrhythmic strategies in patients with atrial fibrillation managed by cardiologists and internists: Antithrombotic Agents in Atrial Fibrillation (ATA-AF) survey.

Aims: To provide insights on the antiarrhythmic management of atrial fibrillation among patients enrolled in the Antithrombotic Agents in Atrial Fibrillation (ATA-AF) study, and to assess the adherence of the Italian cardiologists and internists to guidelines recommendations.

Methods And Results: The ATA-AF study is a multicenter, observational study with prospective data collection on the management and treatment of patients with atrial fibrillation. From March to July 2010, 6910 patients with atrial fibrillation were recruited in 164 Italian Cardiology (Card) and 196 Internal Medicine (IMed) centers.

Epidemiology of atrial fibrillation: European perspective.

In the last 20 years, atrial fibrillation (AF) has become one of the most important public health problems and a significant cause of increasing health care costs in western countries. The prevalence of AF is increasing due to our greater ability to treat chronic cardiac and noncardiac diseases, and the improved ability to suspect and diagnose AF. At the present time, the prevalence of AF (2%) is double that reported in the last decade.

Evaluation of damaging effects of splicing mutations: validation of an in vitro method for diagnostic laboratories.

Background: Pre-mRNA splicing defects may have an important impact on clinical phenotype in several diseases, but often their pathogenic role is difficult to demonstrate. The aim of this study was to validate an in vitro method to assess the effects of putative splicing variants.

Materials And Methods: We studied three novel variants in vitro using a novel minigene approach and compared results with in silico and ex vivo strategies from patient samples.

[Remarks on the guideline recommendations for cardioverter-defibrillator implantation for primary prevention of sudden cardiac Death in patients with severe ventricular dysfunction. Consensus Document of the Italian Association of Hospital Cardiologists (ANMCO)/Italian Society of Cardiology (SIC)/Italian Association of Arrhythmology and Cardiac Pacing (AIAC)].

The indications for implantable cardioverter-defibrillator (ICD) therapy for the prevention of sudden cardiac death in patients with severe left ventricular dysfunction have rapidly expanded over the last 10 years on the basis of the very satisfying results of the numerous randomized clinical trials that have provided the framework for guidelines. However, the analysis of clinical practice in the real world has highlighted some important criticisms in the complex process of selection-management of those patients candidates for ICD therapy: 1) approximately one fourth of all ICD implantations is not justified by clinical evidence, 2) approximately one half of patients with an indication for ICD therapy do not undergo implantation, 3) the benefits from ICD therapy do not apply uniformly to all patients, 4) the relationship between the lifesaving benefit and the potential for harm of ICD therapy is still scarcely known. The main reason for this clinical scenario can be ascribed to the guideline recommendations that are based only on few standard cut-off criteria and therefore too generic and insufficiently detailed.

Stroke prophylaxis in high-risk patients with atrial fibrillation: rhythm vs. rate control strategy.

Purpose: "Rhythm" and "Rate" control strategies require partially different organization, and a different involvement of Specialists and General Practitioners; we verified whether the strategy assignment modified the approach to stroke prophylaxis.

Methods: Survey in general practice: 233 GPs identified all patients with codified atrial fibrillation (AF) diagnosis, checked the diagnosis (ECG/hospital discharge document), and filled a structured questionnaire on stroke risk-factors, prophylactic therapy, and reasons for warfarin non prescription in CHADS ≥2 patients. Data were collected as an "aggregate.

Indication to cardioverter-defibrillator therapy and outcome in real world primary prevention. Data from the IRIDE [Italian registry of prophylactic implantation of defibrillators] study.

Aims: Several trials demonstrated the life saving role of implantable cardioverter-defibrillators (ICD) in primary prevention of sudden cardiac death (SCD). The aim was to evaluate the clinical characteristics and 4-year outcome of consecutive patients treated in clinical practice by prophylactic ICD implantation on the basis of class I recommendations and up-to-date ICD programming.

Methods And Results: IRIDE multi-center, prospective and observational study enrolled 604 consecutive patients (mean age: 66 ± 10 years) treated by ICD between 01/01/2006 and 30/06/2010.
