[Endocarditis complicated by anterior myocardial infarction: a case report. What the guidelines do not say].

Acute myocardial infarction is an uncommon complication of infective endocarditis, burdened by high mortality and often underdiagnosed. Due to its reduced frequency, current guidelines do not always highlight this condition or provide clear indications regarding treatment. We present a case of acute coronary syndrome induced by the occlusion of the anterior descending artery, due to a septic embolus and treated by aspiration of the embolic material.

The Impact of the COVID-19 Outbreak on Patients' Adherence to PCSK9 Inhibitors Therapy.

PCSK9 inhibitors (PCSK9i) are monoclonal antibodies that have been shown to be effective in reducing both LDL cholesterol (LDL-C) values and major cardiovascular events in patients at high cardiovascular risk. Adherence to PCSK9i is critical for the success of the treatment. The aim of the present study is to evaluate patients' adherence to PCSK9i during the COVID-19 pandemic.

Global Left Ventricular Myocardial Work Efficiency in Heart Failure Patients with Cardiac Amyloidosis: Pathophysiological Implications and Role in Differential Diagnosis.

Introduction: Cardiac amyloidosis (CA) is an infiltrative cardiomyopathy and a common cause of heart failure with preserved and mid-range ejection fraction (HFpEF and HFmrEF). Left ventricular (LV) systolic assessment is pivotal in differential diagnostic and prognostic stratification in CA. However, nondeformation and deformation-based parameters classically implied had many limitations.

The Role of New Imaging Technologies in the Diagnosis of Cardiac Amyloidosis.

Cardiac amyloidosis is an infiltrative disorder caused by transthyretin or immunoglobulin free light-chain deposition, which determines clinical disease with similar phenotype but different time course, prognosis and therapy. Multimodality imaging is the cornerstone for disease diagnosis and management. Multimodality imaging has revolutionized the approach to the disease favoring its awareness and simplifying its diagnosis, especially in ATTR cardiac amyloidosis.

Stress Echo 2030: The Novel ABCDE-(FGLPR) Protocol to Define the Future of Imaging.

With stress echo (SE) 2020 study, a new standard of practice in stress imaging was developed and disseminated: the ABCDE protocol for functional testing within and beyond CAD. ABCDE protocol was the fruit of SE 2020, and is the seed of SE 2030, which is articulated in 12 projects: 1-SE in coronary artery disease (SECAD); 2-SE in diastolic heart failure (SEDIA); 3-SE in hypertrophic cardiomyopathy (SEHCA); 4-SE post-chest radiotherapy and chemotherapy (SERA); 5-Artificial intelligence SE evaluation (AI-SEE); 6-Environmental stress echocardiography and air pollution (ESTER); 7-SE in repaired Tetralogy of Fallot (SETOF); 8-SE in post-COVID-19 (SECOV); 9: Recovery by stress echo of conventionally unfit donor good hearts (RESURGE); 10-SE for mitral ischemic regurgitation (SEMIR); 11-SE in valvular heart disease (SEVA); 12-SE for coronary vasospasm (SESPASM). The study aims to recruit in the next 5 years (2021-2025) ≥10,000 patients followed for ≥5 years (up to 2030) from ≥20 quality-controlled laboratories from ≥10 countries.

Regulation of Inflammation and Oxidative Stress by Formyl Peptide Receptors in Cardiovascular Disease Progression.

G protein-coupled receptors (GPCRs) are the most important regulators of cardiac function and are commonly targeted for medical therapeutics. Formyl-Peptide Receptors (FPRs) are members of the GPCR superfamily and play an emerging role in cardiovascular pathologies. FPRs can modulate oxidative stress through nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-dependent reactive oxygen species (ROS) production whose dysregulation has been observed in different cardiovascular diseases.

Impact of synchronous atrioventricular delay optimization on left ventricle flow force angle evaluated by echocardiographic particle image velocimetry.

Purpose: To evaluate the improvement in electrical synchrony and left ventricle (LV) hemodynamics provided by combining the dynamic atrioventricular delay (AVD) of SyncAV CRT and the multiple LV pacing sites of MultiPoint pacing (MPP).

Methods: Patients with LBBB and QRS duration (QRSd) > 140 ms implanted with a CRT-D or CRT-P device and quadripolar LV lead were enrolled in this prospective study. During a post-implant follow-up visit, QRSd was measured from 12-lead surface electrograms by experts blinded to pacing configurations.

Infective Endocarditis: Echocardiographic Imaging and New Imaging Modalities.

Infective endocarditis (IE) is a rare disease with a significant impact and an increasing mortality despite earlier diagnosis and surgical intervention. It is related to several and the main etiological agents are the Gram-positive cocci. The new guidelines propose new diagnostic criteria that consider the potentiality on integrated multimodality imaging.

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.

Network Medicine: A Clinical Approach for Precision Medicine and Personalized Therapy in Coronary Heart Disease.

Early identification of coronary atherosclerotic pathogenic mechanisms is useful for predicting the risk of coronary heart disease (CHD) and future cardiac events. Epigenome changes may clarify a significant fraction of this "missing hereditability", thus offering novel potential biomarkers for prevention and care of CHD. The rapidly growing disciplines of systems biology and network science are now poised to meet the fields of precision medicine and personalized therapy.

Anesthesiological Management in Transcatheter Mitral Valve Repair With MitraClip: Beyond the EVEREST Criteria.

Percutaneous mitral valve repair with the MitraClip system recently emerged as a viable and less invasive therapeutic option in patients with severe mitral regurgitation deemed to be high-risk surgical candidates. Mitral valve morphology and geometry features are key elements for MitraClip eligibility. In the setting of functional mitral regurgitation, the presence of a leaflet coaptation gap due to advanced left ventricle remodeling can be a potential exclusion criterion for MitraClip therapy.

Significant functional mitral regurgitation affects left atrial function in heart failure patients: haemodynamic correlations and prognostic implications.

Aims: Functional mitral regurgitation (FMR) is a well-known pathophysiological factor in heart failure (HF) patients, and left atrial function (LAF) is a novel determinant of clinical status and outcome in this setting. However, little is known about the pathophysiological role of FMR on LAF in HFrEF patients. Aim of this study is to explore the possible interplay between the severity of FMR and LAF in heart failure with reduce ejection fraction (HFrEF) patients and their possible consequences.

Interactive role of diastolic dysfunction and ventricular remodeling in asymptomatic subjects at increased risk of heart failure.

Diastolic dysfunction (DD) and left ventricular remodeling (LVR) characterize patients at risk for heart failure (HF). To assess the prognostic impact of different diastolic function algorithms and a complex LVR classification (CRC) in asymptomatic subjects with preserved ejection fraction (EF) at risk for HF. We analyzed 1923 asymptomatic patients (male 43%; age 57, 33-76 years) with at least one cardiovascular risk factor and preserved (> 50%) EF.

Transcatheter Aortic Valve Replacement and Cardiac Resynchronization Therapy in Cancer-Related Cardiotoxicity.

Cardiotoxicity related to antineoplastic agents is a rising and growing issue, therefore early recognition and prompt management can impact on the overall prognosis of cancer patients. We report the case of a 70-year-old woman without cardiovascular risk factors, with a medical history of non-Hodgkin lymphoma and chronic myeloid leukemia treated with chemotherapy and radiotherapy, who underwent transcatheter aortic valve replacement for severe aortic stenosis and cardiac resynchronization therapy for further development of complete left bundle branch block, with a significant improvement of her functional status and left ventricle systolic function in a long-term follow-up.

Reference Ranges and Physiologic Variations of Left ' Ratio in Healthy Adults: Clinical and Echocardiographic Correlates.

Background: Transthoracic Doppler echocardiographic examination is commonly performed to define the diastolic ventricular function since it is widely available, noninvasive, and inexpensive with respect to other diagnostic imaging modalities. However, data regarding age- and gender-matched reference values are scanty and sometimes conflicting. This study aims to explore the physiologic variations of left ventricular (LV) ' ratio as assessed in a large cohort of healthy adults and to investigate clinical and echocardiographic correlates.

Prognostic Value of a Tissue Doppler Index of Systodiastolic Function in Patients with Asymptomatic Heart Failure.

Introduction: Doppler echocardiography with early diastolic transmitral velocity (E)/early mitral annular diastolic velocity (E') ratio has been proposed as the best predictor for evaluating left ventricle (LV) filling pressure. A dimensionless index E/(E' × S') ratio (S' = systolic mitral annulus velocity) resulted in readily, reproducible, and reliable predictor of LV filling pressure. We assessed the prognostic impact of E/E' × S') in patients with asymptomatic heart failure (HF).

The mitral-to-aortic flow-velocity integral ratio in the real world echocardiographic evaluation of functional mitral regurgitation before and after percutaneous repair.

Introduction: Percutaneous mitral valve repair (PMVR) using MitraClip system has emerged as a therapeutic option for patients with functional severe mitral regurgitation (FMR) at prohibitive risk for surgery. In this setting, the echocardiographic assessment of FMR severity is challenging because the traditional echocardiographic methods have important limitations. The aim of this study was to assess the accuracy and reliability of a simple Doppler index, the mitral/aortic flow velocity integral ratio (MAVIR), to evaluate residual FMR severity after PMVR.

Classification and Prognostic Evaluation of Left Ventricular Remodeling in Patients With Asymptomatic Heart Failure.

Patients with asymptomatic heart failure (HF; stage A and B) are characterized by maladaptive left ventricular (LV) remodeling. Classic 4-group classification of remodeling considers only LV mass index and relative wall thickness as variables. Complex remodeling classification (CRC) includes also LV end-diastolic volume index.

Transcranial Doppler ultrasonography: From methodology to major clinical applications.

Non-invasive Doppler ultrasonographic study of cerebral arteries [transcranial Doppler (TCD)] has been extensively applied on both outpatient and inpatient settings. It is performed placing a low-frequency (≤ 2 MHz) transducer on the scalp of the patient over specific acoustic windows, in order to visualize the intracranial arterial vessels and to evaluate the cerebral blood flow velocity and its alteration in many different conditions. Nowadays the most widespread indication for TCD in outpatient setting is the research of right to left shunting, responsable of so called "paradoxical embolism", most often due to patency of foramen ovale which is responsable of the majority of cryptogenic strokes occuring in patients younger than 55 years old.

Prevalence and Prognostic Impact of Metabolic Syndrome in Asymptomatic (Stage A and B Heart Failure) Patients.

Background: Metabolic syndrome (MS) has an increased risk of cardiovascular events. Its relationship with asymptomatic left ventricular dysfunction (LVD) and prognosis has not been completely clarified.

Objectives: To determine, in asymptomatic patients (Stage A, B heart failure, HF), whether MS is associated with left ventricular systolic dysfunction (LVSD) and left ventricular diastolic dysfunction and its predictive role for cardiovascular events.

The role of new echocardiographic techniques in athlete's heart.

'Athlete's heart' is a common term for the various adaptive changes induced by intensive exercise. Exercise causes alterations of the heart in hemodynamic response to the increased systemic and pulmonary demand during exercise. The understanding of these adaptations is of high importance, since they may overlap with those caused by pathological conditions.
