Prognostic Value of Malnutrition, Frailty, and Physical Performance in Transthyretin Cardiac Amyloidosis: Insights From a Prospective Multicenter Cohort Study.

Background: The prevalence of transthyretin cardiac amyloidosis among older adults (often octogenarians) is increasing. We aimed to determine whether age and geriatric syndromes bear any impact on the management and outcomes in transthyretin cardiac amyloidosis and assess the risk of ageism.

Methods: In a prospective, multicenter cohort study, 256 patients diagnosed with transthyretin cardiac amyloidosis from March 2021 to March 2024 underwent comprehensive geriatric assessment (CGA).

Myosin-ATPase inhibitor in real-world patients with obstructive HCM: a report by the Cardiomyopathies and Pericardial Diseases WG of the Italian Society of Cardiology.

Introduction: Approximately two-thirds of patients suffering from hypertrophic cardiomyopathy present with an obstructive (HOCM) physiology. For years, medical therapy has been limited to beta blockers, verapamil and/or disopyramide. Recently, a novel class of drugs, the allosteric inhibitors of the cardiac-specific myosin head adenosine triphosphatase (ATPase), have been demonstrated to be effective in relieving the dynamic obstruction and related clinical condition.

Change in prevalence of ATTR variants in Italy - Results from a National Survey.

Introduction: Hereditary transthyretin amyloidosis (ATTRv) is a rare, heterogenous, inherited disorder caused by over 130 gene mutations. Its prevalence was estimated to 4.33/million in 2020 in Italy.

Advances in the Therapy of Light Chain Cardiac Amyloidosis.

Systemic light chain (AL) amyloidosis stems from abnormal production of amyloidogenic immunoglobulin light chains by plasma cells or B-cell disorders. It can present locally or systemically, with systemic forms posing significant mortality risks, especially if cardiac involvement is present. Delayed diagnosis due to nonspecific symptoms leads to progressive organ dysfunction.

Genotype-Phenotype Correlations in ATTR Amyloidosis: A Clinical Update.

Hereditary transthyretin-related amyloidosis (hATTR) is the most common form of familial amyloidosis. It is an autosomal dominant disease caused by a pathogenic variant in the TTR gene. More than 140 TTR gene variants have been associated with hATTR, with the Val30Met variant representing the most common worldwide.

The Role of Echocardiography for the Clinical Diagnosis, Risk Stratification, and Management of Cardiac Amyloidosis.

Amyloidosis is a rare, heterogeneous group of diseases characterized by extracellular infiltration and deposition of misfolded fibrils in different organs and tissues. A timely diagnosis is important as it can improve outcome. Echocardiography has emerged as a powerful tool to prompt suspicion and refer patients to second-level evaluation to reach a definitive diagnosis.

Effect of beta-blockers and angiotensin receptor blockers in reducing the aortic growth rate in children with bicuspid aortic valve-related aortopathy.

Aims: The aim of this study is to evaluate the effect of beta-blockers and angiotensin receptor blockers in reducing the aortic growth rate in children with bicuspid aortic valve (BAV)-related aortopathy and ascending phenotype.

Methods: Consecutive paediatric patients (≤16 years) with BAV and ascending aorta (AsAo) dilation (z-score > 3) were enrolled in this observational retrospective cohort study. Patients receiving prophylactic treatment with either atenolol (0.

Prevalence and Clinical Significance of Intraventricular Conduction Disturbances in Hospitalized Children.

Data on the prevalence and clinical significance of interventricular conduction disturbances (IVCDs) in children are scarce. While incomplete right bundle branch blocks (IRBBBs) seem to be the most frequent and benign findings, complete bundle blocks and fascicular blocks are often seen in children with congenital/acquired cardiac conditions. This study aims to delineate the prevalence and the diagnostic accuracy of IVCD in children admitted to a paediatric cardiology unit.

OCT angiography indices and the choroidal vascularity index in wild-type transthyretin (TTR) amyloidosis (ATTRwt).

Purpose: Retinal angiopathy represents a well-known ocular manifestation of hereditary transthyretin amyloidosis (ATTRv). Until recently, there have been no reports on retinal changes in ATTRwt. In this retrospective observational clinical study, we aimed to determine whether vessel density (VD) indices and the choroidal vascularity index (CVI) could offer insights into retinal and choroidal vascular changes among patients affected by ATTRwt.

[Clinical and genetic manifestations of left ventricular non-compaction in children].

Left ventricular non-compaction (LVNC) is a myocardial disease characterized by a two-layered structure typically seen at the apical and lateral left portions of the ventricular myocardium, distal to the papillary muscles. While considered a rare disease, its prevalence in children is increasing due to the increased awareness of this condition and improved resolution of imaging techniques. The etiology is heterogeneous, ranging from inherited conditions to acquired diseases.

RETRACTED: Left Ventricular Non-Compaction in Children: Aetiology and Diagnostic Criteria.

Left ventricular non-compaction (LVNC) is a heterogeneous myocardial disorder characterized by prominent trabeculae protruding into the left ventricular lumen and deep intertrabecular recesses. LVNC can manifest in isolation or alongside other heart muscle diseases. Its occurrence among children is rising due to advancements in imaging techniques.

Cardiovascular Involvement in Fabry's Disease: New Advances in Diagnostic Strategies, Outcome Prediction and Management.

Cardiovascular involvement is common in Fabry's disease and is the leading cause of morbidity and mortality. The research is focused on identifying diagnostic clues suggestive of cardiovascular involvement in the preclinical stage of the disease through clinical and imaging markers. Different pathophysiologically driven therapies are currently or will soon be available for the treatment of Fabry's disease, with the most significant benefit observed in the early stages of the disease.

Targeted Therapies in Pediatric and Adult Patients With Hypertrophic Heart Disease: From Molecular Pathophysiology to Personalized Medicine.

Hypertrophic cardiomyopathy is a myocardial disease defined by an increased left ventricular wall thickness not solely explained by abnormal loading conditions. It is often genetically determined, with sarcomeric gene mutations accounting for around 50% of cases. Several conditions, including syndromic, metabolic, infiltrative, and neuromuscular diseases, may present with left ventricular hypertrophy, mimicking the hypertrophic cardiomyopathy phenotype but showing a different pathophysiology, clinical course, and outcome.

Prevalence and clinical significance of right ventricular pulmonary arterial uncoupling in cardiac amyloidosis.

Background: This study aims to evaluate the prevalence and the clinical significance of the right ventricular pulmonary arterial (RV-PA) uncoupling in patients with cardiac amyloidosis (CA).

Methods: The study population consisted in 92 consecutive patients with CA (age 71.1 ± 12.

Multimodality Imaging in Arrhythmogenic Left Ventricular Cardiomyopathy.

The term arrhythmogenic cardiomyopathy (ACM) describes a large spectrum of myocardial diseases characterized by progressive fibrotic or fibrofatty replacement, which gives the substrate for the occurrence of ventricular tachyarrhythmias and the development of ventricular dysfunction. This condition may exclusively affect the left ventricle, leading to the introduction of the term arrhythmogenic left ventricular cardiomyopathy (ALVC). The clinical features of ALVC are progressive fibrotic replacement with the absence or mild dilation of the LV and the occurrence of ventricular arrhythmias within the left ventricle.

The Role of Genetic Testing in Patients with Heritable Thoracic Aortic Diseases.

Heritable thoracic aortic disease (HTAD) is a term used to define a large group of disorders characterized by the occurrence of aortic events, mainly represented by aneurysm or dissection. These events generally involve the ascending aorta, although the involvement of other districts of the aorta or peripheral vessels may occur. HTAD can be classified as non-syndromic if the disorder is limited to the aorta, and syndromic when associated with extra-aortic features.

Pathophysiology, Functional Assessment and Prognostic Implications of Nutritional Disorders in Systemic Amyloidosis.

Gastrointestinal involvement is a common clinical feature of patients with systemic amyloidosis. This condition is responsible for invalidating gastrointestinal symptoms, a significant macro and micronutrient deficit, and is a marker of disease severity. Gastrointestinal involvement should be actively sought in patients with systemic amyloidosis, while its diagnosis is challenging in patients with isolated gastrointestinal symptoms.

Medical treatment of patients with hypertrophic cardiomyopathy: An overview of current and emerging therapy.

Several treatments have demonstrated safety and effectiveness in the treatment of patients with hypertrophic cardiomyopathy; however, no drug has been shown to modify the natural history of the disease or to decrease maximal wall thickness. 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.
