Importance: Diagnostic screening for Anderson-Fabry cardiomyopathy (AFC) is performed in the presence of specific clinical red flags in patients with hypertrophic cardiomyopathy (HCM) older than 25 years. However, left ventricular outflow tract obstruction (LVOTO) has been traditionally considered an exclusion criteria for AFC. Objective: To examine a series of patients diagnosed with HCM and severe basal LVOTO undergoing myectomy in whom the diagnosis of AFC was suspected by the cardiac surgeon intraoperatively and confirmed by histological and genetic examinations...

BACKGROUND: Prognosis of hypertrophic cardiomyopathy (HCM) is particularly heterogeneous. Patients with nonobstructive HCM (NOCM) are thought to be at relatively low-risk as compared with obstructive HCM (HOCM) with no need of major treatment options. However, available evidence of NOCM comes mainly from tertiary centers where a referral bias is likely to occur. Aim of this study was to perform a systematic review and meta-analysis of the published literature on hypertrophic cardiomyopathy (HCM) in order to outline differences in presenting features and long-term outcome between NOCM and HOCM...

BACKGROUND: Fabry Disease (FD) is characterized by globotriaosylceramide-3 (Gb3) accumulation in several tissues and a small fibre neuropathy (SFN), however the underlying mechanisms are poorly known. This study aimed to: 1) ascertain the presence of Gb3 deposits in skin samples, by an immunofluorescence method collected from FD patients with classical GLA mutations or late-onset FD variants or GLA polymorphisms; 2) correlate skin GB3 deposits with skin innervation. METHODS: we studied 52 genetically-defined FD patients (32 with classical GLA mutations and 20 with late-onset variants or GLA polymorphisms), 15 patients with SFN associated with a specific cause and 22 healthy controls...

Aims: Although cardiac amyloidosis (CA) is characterized by significant left atrial (LA) dilatation, the characteristics of LA function remain to be fully investigated. Methods and results: We assessed LA function by speckle-tracking echocardiography in 124 patients with CA and sinus rhythm: 68 with light chain (AL), 29 with mutant (ATTRm), 27 with wild-type (ATTRwt) transthyretin amyloidosis. Conventional and strain-derived parameters, including LA peak longitudinal strain (LS) and strain rate (peak LSR: reservoir function; early LSR: conduit function; late LSR: active function), were assessed compared between CA patients and 20 healthy controls of similar age and gender...

Transthyretin amyloidosis is a rare, life-threatening disease resulting from aggregation and deposition of transthyretin amyloid fibrils in various tissues. There are 2 predominate phenotypic presentations of the disease: transthyretin familial amyloid polyneuropathy, which primarily affects the peripheral nerves, and transthyretin cardiomyopathy (TTR-CM), which primarily affects the heart. However, there is a wide overlap with symptoms at presentation and disease course being highly variable and influenced by the underlying transthyretin mutation, age of the affected individual, sex, and geographic location...

Advances in cardiac imaging have resulted in greater recognition of cardiac amyloidosis in everyday clinical practice, but the diagnosis continues to be made in patients with late-stage disease, suggesting that more needs to be done to improve awareness of its clinical manifestations and the potential of therapeutic intervention to improve prognosis. Light chain cardiac amyloidosis, in particular, if recognized early and treated with targeted plasma cell therapy, can be managed very effectively. For patients with transthyretin amyloidosis, there are numerous therapies that are currently in late-phase clinical trials...

Aims: Wild-type transthyretin amyloidosis (ATTRwt) is mostly considered a disease predominantly of elderly male, characterized by concentric LV hypertrophy, preserved LVEF, and low QRS voltages. We sought to describe the characteristics of a large cohort of ATTRwt patients to better define the disease. Methods and results: Clinical findings of consecutive ATTRwt patients diagnosed at 2 centres were reviewed. ATTRwt was diagnosed histologically or non-invasively (LV hypertrophy ≥12 mm, intense cardiac uptake at 99mTc-DPD scintigraphy and AL exclusion)...

BACKGROUND: Severe left ventricular (LV) systolic dysfunction is an uncommon complication of hypertrophic cardiomyopathy (HCM) that is associated with poor prognosis. Small observational series suggest that patients with rare causes of HCM are more likely to develop systolic impairment than those with idiopathic disease or mutations in cardiac sarcomeric protein genes. The aim of this study was to test this hypothesis by comparing the prevalence of systolic dysfunction and its impact on prognosis in patients with different causes of HCM...

Hypertrophic cardiomyopathy (HCM) is mainly associated with myosin, heavy chain 7 (MYH7) and myosin binding protein C, cardiac (MYBPC3) mutations. In order to better explain the clinical and genetic heterogeneity in HCM patients, in this study, we implemented a target-next generation sequencing (NGS) assay. An Ion AmpliSeq™ Custom Panel for the enrichment of 19 genes, of which 9 of these did not encode thick/intermediate and thin myofilament (TTm) proteins and, among them, 3 responsible of HCM phenocopy, was created...
