Impact of SARS-Cov-2 infection in patients with hypertrophic cardiomyopathy: results of an international multicentre registry.

Aims: To describe the natural history of SARS-CoV-2 infection in patients with hypertrophic cardiomyopathy (HCM) compared with a control group and to identify predictors of adverse events.

Methods And Results: Three hundred and five patients [age 56.6 ± 16.

Characterization of hereditary transthyretin cardiac amyloidosis in Spain.

Introduction And Objectives: Hereditary transthyretin amyloidosis (hATTR) is a disease caused by mutations in the transthyretin gene that frequently shows cardiac involvement due to amyloid deposition in the myocardium. Our objective was to identify cardiac involvement in a Spanish cohort.

Methods: Retrospective multicenter study of patients diagnosed with hATTR with cardiac involvement from Spanish centers.

Long-term prognosis of women with Brugada syndrome and electrophysiological study.

Background: A male predominance in Brugada syndrome (BrS) has been widely reported, but scarce information on female patients with BrS is available.

Objective: The purpose of this study was to investigate the clinical characteristics and long-term prognosis of women with BrS.

Methods: A multicenter retrospective study of patients diagnosed with BrS and previous electrophysiological study (EPS) was performed.

Clinical Findings and Prognosis of Danon Disease. An Analysis of the Spanish Multicenter Danon Registry.

Introduction And Objectives: Danon disease (DD) is caused by mutations in the LAMP2 gene. It is considered a multisystemic disease characterized by hypertrophic cardiomyopathy with pre-excitation and extreme hypertrophy, intellectual disability, myopathy, childhood presentation, and worse prognosis in men. There are scarce data on the clinical characteristics and prognosis of DD.

Plan of Action for Inherited Cardiovascular Diseases: Synthesis of Recommendations and Action Algorithms.

The term inherited cardiovascular disease encompasses a group of cardiovascular diseases (cardiomyopathies, channelopathies, certain aortic diseases, and other syndromes) with a number of common characteristics: they have a genetic basis, a familial presentation, a heterogeneous clinical course, and, finally, can all be associated with sudden cardiac death. The present document summarizes some important concepts related to recent advances in sequencing techniques and understanding of the genetic bases of these diseases. We propose diagnostic algorithms and clinical practice recommendations and discuss controversial aspects of current clinical interest.

Diagnostic Approach to Unexplained Cardiac Arrest (from the FIVI-Gen Study).

Unexplained cardiac arrest (UCA) can be caused by low-penetrance genetic disorders. The aim of this cross-sectional study is to assess the usefulness of a new diagnostic protocol: Thirty-five patients were recruited from 9 Spanish centers. Electrocardiogram, echocardiogram, and coronary catheterization were used to rule out electrical or structural heart disease in all subjects.

Phenotypic patterns of right ventricular dysfunction: analysis by cardiac magnetic imaging.

The aim of this study was to use magnetic resonance imaging (MRI) to classify the morphological changes and remodeling of the right ventricle (RV) that occur in different clinical situations and that have an impact on RV function. Most literature has traditionally focused on the left ventricle (LV) and as a result, few studies analyze RV behavior and remodeling. The study evaluated all cardiac MRI performed at our center from 2008 to 2010.

Predictors of renal dysfunction at 1 year in heart transplant patients.

Background: Renal dysfunction (RD) is one of the most significant long-term complications of heart transplantation (HT). Although RD is generally attributed to a direct effect of calcineurin inhibitors, it is more probable that multiple factors contribute to its development. The aim of this study was to search for predictor variables of RD at 1 year after HT.

Reversal of protein-losing enteropathy after heart transplantation in young patients.

Protein-losing enteropathy is a rare but life-threatening complication that occurs in some patients who develop intestinal lymphangiectasis secondary to increased systemic venous pressure. Although different forms of treatment have been tried, with varying results, the majority were reported to be unsuccessful. The aim of this study was to demonstrate that heart transplantation may be an appropriate therapeutic option for patients who do not respond to medical treatment.
