Aims: Our aim was to assess the clinical and prognostic significance of the left ventricular (LV) hypercontractile phenotype (HP) in hypertrophic cardiomyopathy (HCM), which until now remains unclear.
Methods And Results: We enrolled 1533 HCM patients (age 51 ± 15 years, 965 males, 63%) with ejection fraction (EF) ≥ 50%, referred for rest transthoracic echocardiography (TTE) in 27 laboratories from 13 countries. Two-dimensional volumetric TTE assessment included LV outflow tract gradient (LVOTG), LV EF, and LV force (systolic blood pressure + LVOTG/ESV, mmHg/mL).
Background: In Hypertrophic cardiomyopathy (HCM) increasing evidence suggests left atrial (LA) remodelling plays a critical role in disease progression. Traditional static LA size measurements, while established as risk markers, do not reflect the dynamic nature of LA changes over time.
Objectives: This study aimed to define long-term LA remodelling trajectories in HCM and assess their prognostic value for predicting atrial fibrillation (AF), sudden cardiac death (SCD), and heart failure (HF) death.
Hypertrophic cardiomyopathy (HCM) is a genetic heart disorder defined by the presence of a maximal wall thickness of at least 15 mm with two main forms: obstructive (oHCM) and nonobstructive (nHCM). While oHCM is characterized by left ventricular (LV) outflow tract obstruction (LVOTO), nHCM lacks this feature and shows significant variability in its hemodynamic and anatomical traits. In nHCM, LV hypertrophy (LVH) presents diverse morphologies, including apical hypertrophy and reverse septal curvature, the latter potentially causing mid-ventricular obstruction and near-complete LV emptying.

Background: Hereditary transthyretin (ATTRv) amyloidosis is rare, autosomal dominant disease with a fatal outcome if left untreated. Early stages detection is crucial for intervention. We aimed identifying early indexes of cardiac involvement and their eventual correlation with neurological indexes, in pre-symptomatic subjects with TTR gene mutation.

In patients with severe left ventricle hypertrophy and aortic stenosis, the presence of intraventricular gradient should always be investigated. Its prompt recognition enables a precise diagnosis and safe treatment of both conditions. We report 2 cases demonstrating a successful and novel approach to this clinical situation.

Introduction: Delay in arterial hypertension (AH) diagnosis and late therapy initiation may affect progression towards hypertensive-mediated organ damage (HMOD) and blood pressure (BP) control.
Aim: We aimed to assess the impact of time-to-therapy on BP control and HMOD in patients receiving AH diagnosis.
Methods: We analysed data from the Campania Salute Network, a prospective registry of hypertensive patients (NCT02211365).
Background: Sex-specific differences in left ventricular (LV) geometry might help in developing tailored strategies for hypertension management.
Objectives: The purpose of the study was to evaluate sex-related differences in LV geometry at baseline and over time in hypertension.
Methods: From a prospective registry, we included hypertensives without prevalent cardiovascular disease, incident myocardial infarction, chronic kidney disease > stage III, and with normal LV ejection fraction.

Background: In obstructive hypertrophic cardiomyopathy (HOCM), disopyramide is used in patients who remain symptomatic despite -blockers or verapamil. However, effectiveness of disopyramide therapy has not been clearly established due to inconsistent definition of responders and the insufficient length of follow-ups reported in literature. To address these shortcomings, we have conducted a retrospective analysis from detailed databases with long follow-up, from two HCM Referral Centers.

Hypertrophic Cardiomyopathy (HCM) presents a complex diagnostic and prognostic challenge due to its heterogeneous phenotype and clinical course. Artificial Intelligence (AI) and Machine Learning (ML) techniques hold promise in transforming the role of Electrocardiography (ECG) in HCM diagnosis, prognosis, and management. AI, including Deep Learning (DL), enables computers to learn patterns from data, allowing for the development of models capable of analyzing ECG signals.

Early detection of the phenotypic expression of the disease in genetic carriers without LVH (Gen+/Phen-) is crucial for emerging therapies. This clinical study aims to identify echocardiographic predictors of phenotypic development in Gen+/Phen-.

Introduction: No data are available on the diagnostic algorithms recommended by guidelines for the assessment of diastolic dysfunction (DD) in patients with arterial hypertension.
Aim: To fill this gap, we evaluated diastolic function in hypertensive patients with and without LVH matched with healthy subjects by applying 2016 American Society of Echocardiography-European Association of Cardiovascular Imaging Guidelines for the evaluation of LV diastolic function.
Methods: 717 healthy and hypertensives with normal LV ejection fraction and with and without LV hypertrophy (LVH), matched 1:1:1 from two prospective registries, represented the study population.

Background And Aim: Atrial fibrillation (AF) is the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM) with significant effects on outcome. We aim to compare the left atrial (LA) diameter measurement with HCM-AF Score in predicting atrial fibrillation (AF) development in HCM.
Methods: From the regional cohort of the Campania Region, Italy, 519 HCM patients (38% women, age45 ± 17 years) without history of AF, were enrolled in the study.

Aortic stenosis (AS) is a valvular heart disease that significantly contributes to cardiovascular morbidity and mortality worldwide. The condition is characterized by calcification and thickening of the aortic valve leaflets, resulting in a narrowed orifice and increased pressure gradient across the valve. AS typically progresses from a subclinical phase known as aortic sclerosis, where valve calcification occurs without a transvalvular gradient, to a more advanced stage marked by a triad of symptoms: heart failure, syncope, and angina.

Hypertrophic cardiomyopathy (HCM) is a genetic disease with heterogeneous clinical presentation and prognosis. Within the broad phenotypic expression of HCM, there is a subgroup of patients with a left ventricular (LV) apical aneurysm, which has an estimated prevalence between 2% and 5%. LV apical aneurysm is characterized by an area of apical dyskinesis or akinesis, often associated with regional scarring.

The accurate assessment of aortic valve area and mean pressure gradient is crucial to determine which patients are appropriate candidates for aortic valve replacement. Nowadays, these values can be obtained noninvasively or invasively, with similar results.

The diffusion of next-generation sequencing (NGS)-based approaches allows for the identification of pathogenic mutations of cardiomyopathies and channelopathies in more than 200 different genes. Since genes considered uncommon for a clinical phenotype are also now included in molecular testing, the detection rate of disease-causing variants has increased. Here, we report the prevalence of genetic variants detected by using a NGS custom panel in a cohort of 133 patients with inherited cardiomyopathies (n = 77) or channelopathies (n = 56).

Improvement in our knowledge of the physiopathology of the disease has permitted the development of new therapeutical approaches, including sarcomere modulators and gene therapy. A sarcomere modulator - mavacamten - has been shown to improve exercise capacity, left ventricular outflow tract obstruction, New York Heart Association functional class and health status in a phase 3 trial.
