The 2021 European Society of Cardiology (ESC) screening recommendations for individuals carrying a pathogenic transthyretin amyloidosis variant (ATTRv) are based on expert opinion. We aimed to (i) determine the penetrance ATTRv cardiomyopathy (ATTRv-CM) at baseline; (ii) examine value serial evaluation; and (iii) establish yield first-line diagnostic tests (i.e. electrocardiogram, echocardiogram, laboratory tests) as per ESC position statement.

Tafamidis improves clinical outcomes in transthyretin amyloid cardiomyopathy (ATTR-CM), yet how tafamidis affects cardiac structure and function remains poorly described. This study prospectively analysed the effect of on 12-month longitudinal changes by magnetic resonance (CMR) compared with natural course disease an untreated historic control cohort.

Sex-related differences in prevalence, clinical presentation, and outcome of cardiac channelopathies are increasingly recognized, despite their autosomal transmission hence equal genetic predisposition among sexes. In congenital long-QT syndrome, adult women carry a greater risk for Torsades de pointes sudden death than do men. contrast, Brugada syndrome is observed predominantly men, with considerably higher arrhythmic men women. both conditions, the arrhythmias varies age. Sex-associated...

Even though it has been more than a decade since renal denervation (RDN) was first used to treat hypertension and an intense effort on researching this therapy made, is still not clear how RDN fits into the antihypertensive arsenal. There no question that lowers blood pressure (BP), does so extent at best corresponding one drug. The procedure excellent safety record. However, remains clinically impossible predict whose BP responds not. Long-term efficacy data reduction are unconvincing...

Background Transthyretin amyloid cardiomyopathy (ATTR-CM) often coexists with severe aortic stenosis (AS). Although strain analysis from cardiac MRI and echocardiography was demonstrated to predict coexisting ATTR-CM, comparable data four-dimensional (4D) CT are lacking despite wide availability. Purpose To evaluate the diagnostic performance of 4D CT-derived parameters in identifying ATTR-CM older adults considered for transcatheter valve implantation (TAVI). Materials Methods This...

Background: Despite being the most commonly performed valvular intervention, risk prediction for aortic valve replacement in patients with severe stenosis by currently used scores remains challenging. The study aim was to develop a biomarker-based score means of neuronal network. Methods: In this multicenter study, 3595 were divided into test and validation cohorts (70% 30%) random allocation. Input variables ABC-AS age, cardiac biomarker high-sensitivity troponin T, patient history...

Transthyretin amyloid cardiomyopathy (ATTR-CM) is a frequent concomitant condition in patients with severe aortic stenosis (AS), yet it often remains undetected. This study aims to comprehensively evaluate artificial intelligence-based models developed based on preprocedural and routinely collected data detect ATTR-CM AS planned for transcatheter valve implantation (TAVI).

Systemic amyloidosis is a heterogeneous group of diseases associated with protein misfolding into insoluble beta-sheet rich structures that deposit extracellularly in different organs, eventually compromising their function. There are more than 30 proteins, known to be amyloidogenic “light chain” (AL)-amyloidosis being the most common type, followed by transthyretin (ATTR)-, and amyloid A (AA)-amyloidosis. rare disease an incidence around 10 patients 1 million inhabitants. Recently several...
