Very high-power short-duration radiofrequency ablation in patients with typical atrial flutter: rationale and design of the FASD-HP randomized trial.

Background: The aim of cavotricuspid isthmus (CTI)-dependent flutter ablation is the bidirectional conduction block of the CTI. Very-high-power short-duration (vHPSD) radiofrequency ablation aims to minimize conductive heating and increase resistive heating to create shallower but wider lesions in a very short time, while reducing the risk of collateral tissue damage. Experimental studies have shown that it produces effective transmural lesions with an equal or better safety profile compared to conventional parameters.

Prognostic impact of the findings of the genetic test in left dominant arrhythmogenic cardiomyopathy.

Background: The diagnosis of left dominant arrhythmogenic cardiomyopathy (LDAC) is sometimes complex. The Padua group recently published a document with criteria to identify patients with LDAC, requiring a compatible genetic variant for diagnosis. Due to the gaps in the knowledge of the role of genetics in its pathogenesis, our objective is to describe the findings of the genetic test in patients with LDAC in our center and its prognostic impact.

A Novel Technique of Placing Desfibrillator Leads in Patients with Persistent Left Superior Vena Cava.

Persistent left superior vena cava is the most common thoracic venous anomaly. It is usually asymptomatic, but it can make implanting intracardiac devices difficult.We present a novel technique to facilitate desfibrillator lead implantation in patients with persistent left superior vena cava and the absence of the right superior vena cava.

Outcomes of leadless pacemaker implantation in patients with mechanical heart valves.

Introduction: Device infections constitute a major complication of transvenous pacemakers. Mechanical heart valves (MHV) increase the risk of infective endocarditis (IE) and pacemaker infection, requiring lifelong vitamin K-antagonists (VKA), which may affect patient management. Leadless pacemakers (LP) are associated with low infection rates, posing an attractive option in MHV patients requiring permanent pacing.

A case report of a triad causing platypnoea-orthodeoxia syndrome.

Background: Platypnoea-orthodeoxia syndrome (POS) is a rare condition characterized by hypoxaemia and dyspnoea when changing from a recumbent to an upright position. Diagnosis requires a high clinical suspicion and is often underdiagnosed.

Case Summary: We report a case of POS in a 50-year-old woman with dyspnoea and new-onset atrial fibrillation.

Importance of cardiac magnetic resonance findings in the diagnosis of left dominant arrythmogenic cardiomyopathy.

Introduction And Objectives: Left dominant arrhythmogenic cardiomyopathy (LDAC) has recently been recognized as falling on the spectrum of arrhythmogenic cardiomyopathy. It is characterized by fibroadipose replacement of the left ventricle. The aim of this study was to describe the most frequent forms of clinical presentation of LDAC, imaging findings, and events at follow-up, highlighting the importance of cardiac magnetic resonance (CMR).

One-year efficacy and safety of prasugrel and ticagrelor in patients with acute coronary syndromes: Results from a prospective and multicentre ACHILLES registry.

Background: Prasugrel and ticagrelor have demonstrated higher efficacy than clopidogrel in their main clinical trials for patients with acute coronary syndrome (ACS). However, the long-term prognosis and different clinical characteristics related to the type of antiplatelet prescription in current clinical practice ACS patients have not been analysed in depth. The objective of this study was to analyse the clinical profile of ACS and the efficacy and safety of novel oral P2Y inhibitors in current clinical practice patients discharged afterACS.

Time-to-Effect-Based Dosing Strategy for Cryoballoon Ablation in Patients With Paroxysmal Atrial Fibrillation: Results of the plusONE Multicenter Randomized Controlled Noninferiority Trial.

Background: The optimal dosage of cryotherapy during cryoballoon ablation of pulmonary veins is still unclear. This trial tested the noninferiority of a novel, individualized, cryotherapy-dosing strategy for each vein.

Methods And Results: This prospective, randomized, multicenter, noninferiority study included 140 patients with paroxysmal atrial fibrillation, which was refractory to antiarrhythmic drugs.

The HAS-BLED score predicts long-term major bleeding and death in anticoagulated non-valvular atrial fibrillation patients undergoing electrical cardioversion.

Background: Atrial fibrillation (AF) patients eligible for cardioversion tend to be younger and are at lower risk than 'general' AF clinic populations. We evaluated the incidence of major bleeding and death, as well as the predictive value of the HAS-BLED score in non-valvular AF patients who underwent electrical cardioversion (ECV).

Methods: Consecutive non-valvular AF patients who underwent ECV were recruited.
