2024 European Heart Rhythm Association/Heart Rhythm Society/Asia Pacific Heart Rhythm Society/Latin American Heart Rhythm Society expert consensus statement on catheter and surgical ablation of atrial fibrillation.

In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007, the first joint expert consensus document was issued, guiding healthcare professionals involved in catheter or surgical AF ablation. Mounting research evidence and technological advances have resulted in a rapidly changing landscape in the field of catheter and surgical AF ablation, thus stressing the need for regularly updated versions of this partnership which were issued in 2012 and 2017.

Infliximab Limits Injury in Myocardial Infarction.

Background: The purpose of this study was to investigate a therapeutic approach targeting the inflammatory response and consequent remodeling from ischemic myocardial injury.

Methods And Results: Coronary thrombus aspirates were collected from patients at the time of ST-segment-elevation myocardial infarction and subjected to array-based proteome analysis. Clinically indistinguishable at myocardial infarction (MI), patients were stratified into vulnerable and resilient on the basis of 1-year left ventricular ejection fraction and death.

Rationale and design of the ELEANOR trial early aortic valve surgery versus watchful waiting strategy in severe asymptomatic aortic regurgitation, ACRONYM: ELEANOR.

Background: The optimal treatment of patients with severe symptomatic aortic regurgitation (AR) is state-of-the-art surgery. Asymptomatic patients with advanced left ventricular (LV) dilatation and/or impaired ejection fraction should undergo surgical treatment, but there is no guidelines consensus on cut-off values for this recommendation. Multimodality imaging has brought new tools for the accurate selection of asymptomatic patients at risk of early clinical deterioration, however, prospective and randomized data are pending.

Clinical Impact of the Endo-aortic Clamp for Redo Mitral Valve Surgery.

Aim of this study was to compare redo MV surgery patients undergoing right mini-thoracotomy and EAC with redo MV patients undergoing surgery through other approaches. Redo MV patients from 7 European centers were analyzed. Primary endpoint was 30-day mortality; secondary endpoints were stroke, re-exploration, low cardiac output syndrome (LCOS), respiratory failure, and intensive care unit (ICU) and in-hospital length-of-stay.

Coronary CT Angiography in the Cath Lab: Leveraging Artificial Intelligence to Plan and Guide Percutaneous Coronary Intervention.

The role of coronary CT angiography for the diagnosis and risk stratification of coronary artery disease is well established. However, its potential beyond the diagnostic phase remains to be determined. The current review focuses on the insights that coronary CT angiography can provide when planning and performing percutaneous coronary interventions.

The role of physiology in the contemporary management of coronary artery disease.

Coronary physiology assessment, including epicardial and microvascular investigations, is a fundamental tool in the contemporary management of patients with coronary artery disease. Coronary revascularisation guided by functional evaluation has demonstrated superiority over angiography-only-guided treatment. In patients with chronic coronary syndrome, revascularisation did not demonstrate prognostic advantage in terms of mortality over optimal medical therapy (OMT).

Doxorubicin-induced cardiovascular toxicity: a longitudinal evaluation of functional and molecular markers.

Aims: Apart from cardiotoxicity, the chemotherapeutic doxorubicin (DOX) induces vascular toxicity, represented by arterial stiffness and endothelial dysfunction. Both parameters are of interest for cardiovascular risk stratification as they are independent predictors of future cardiovascular events in the general population. However, the time course of DOX-induced cardiovascular toxicity remains unclear.

Deep learning-based prediction of future myocardial infarction using invasive coronary angiography: a feasibility study.

Background: Angiographic parameters can facilitate the risk stratification of coronary lesions but remain insufficient in the prediction of future myocardial infarction (MI).

Aims: We compared the ability of humans, angiographic parameters and deep learning (DL) to predict the lesion that would be responsible for a future MI in a population of patients with non-significant CAD at baseline.

Methods: We retrospectively included patients who underwent invasive coronary angiography (ICA) for MI, in whom a previous angiogram had been performed within 5 years.

A novel technique of proximal optimization with kissing balloon inflation in bifurcation lesions.

Background: Percutaneous coronary interventions (PCI) of bifurcation lesions poses a technical challenge with a high complication rate. Kissing balloon inflation (KBI) and proximal optimization technique (POT) are used to correct bifurcation carina after stenting. However, both may still lead to uncomplete strut apposition to the side branch (SB) lateral wall.

The Impact of Radiofrequency Wide Circumferential Pulmonary Vein Isolation on Left Atrial Geometry in Patients with Recurrent Atrial Fibrillation.

Purpose: The aim of the study was to investigate the effect of wide area circumferential radiofrequency catheter ablation (WACA) pulmonary vein isolation on left atrium (LA) geometry.

Methods: Seventy-one patients underwent WACA, for recurrent paroxysmal (n = 31) and persistent (n = 40) atrial fibrillation (AF). A three-dimension rotational angiography of the LA was obtained immediately prior to index and repeat procedure.

Determinants of functional significance of coronary bifurcation lesions and clinical outcomes after physiology-guided treatment.

Objectives: To determine the rate of functionally significant (fractional flow reserve, FFR ≤ 0.80) coronary bifurcation stenoses that are considered anatomically significant based on angiographic estimation and to define predictors of functional significance of stenoses in main vessel and side branch.

Background: To date, the rate of functionally significant stenoses in angiographic significant coronary bifurcation stenoses has not been specifically determined.

Bifurcation functional significance score as predictor of mortality: a validating study.

Considerable progress has been made in the treatment of coronary bifurcation stenosis. Anatomical characteristics of the vessel and lesion, however, fail to give information about the functional significance of the bifurcation stenosis. To the best of our knowledge, there is no study that systematically establishes the baseline functional significance of coronary stenosis and its effect on procedural and clinical outcomes.

Clinical inertia in the treatment of heart failure: a major issue to tackle.

Despite an enormous improvement in heart failure management during the last decades, the hospitalization and mortality rate of heart failure patients still remain very high. Clinical inertia, defined as the lack of treatment intensification in a patient not at evidence-based goals for care, is an important underlying cause. Clinical inertia is extensively described in hypertension and type 2 diabetes mellitus, but increasingly recognized in heart failure as well.

Impact of increased venous pressure on kidney function and mortality in cardiovascular patients with preserved ejection fraction.

Right but not left ventricular hemodynamic parameters have been found to be independently associated with adverse renal outcomes in patients with acute decompensated heart failure (HF). To investigate the hemodynamic profile of patients without acute decompensated heart failure and left ventricular ejection fraction >50% referred for elective left and right heart catheterization and to correlate left and right filling pressures, stroke volume and arterial blood pressure to renal function parameters. Subsequently, we tested the hypothesis that right ventricle and left ventricle hemodynamic parameters can predict all-cause mortality in our non-HF subjects.

Feasibility of single position endoscopic laser balloon ablation for atrial fibrillation: The open 8 approach.

Introduction: Ablation without shaft repositioning may make the endoscopic laser ablation system (EAS) more like a single shot approach. We tested the feasibility of wide circumferential ablation (WCA; no carina ablation and no shaft repositioning) in an "open 8" pattern for pulmonary vein isolation (PVI).

Methods And Results: Forty-eight patients (n = 48, age 64.

Treatment of diabetic patients with non-ST-elevation myocardial infarction.

Diabetic patients with non-ST-elevation myocardial infarction represent a group of patients at higher risk of mortality. The lower access to aggressive treatment strategies and suboptimal efficacy of pharmacologic therapies contribute to this inherent risk. This article underscores the importance of providing diabetic patients with more aggressive treatment strategies as well as recent, more effective pharmacologic therapies.

Lack of correlation between platelet reactivity and glycaemic control in type 2 diabetes mellitus patients treated with aspirin and clopidogrel.

The relationship between glycaemic control and platelet reactivity in patients with type 2 diabetes mellitus (DM) on dual antiplatelet therapy is still unclear. A total of 155 consecutive stable angina patients with type 2 DM scheduled for elective percutaneous coronary intervention (PCI) were recruited. All patients were taking aspirin and received a 600-mg loading dose of clopidogrel at least 12 h before intervention.
