This leads to cellular dysfunction in various organs, with cardiovascular compromise being the major cause of morbidity and mortality. This study aimed to provide a comprehensive overview of FD focusing on its genetic, epidemiological, clinical, diagnostic, and therapeutic aspects. This study explored the genetic mutations associated with FD, its epidemiology, clinical phenotypes, cardiac manifestations, diagnostic approaches, and current treatment options. Background: FD is caused by mutations in GLA on the X chromosome, with over 1000 identified variants. Neonatal screening and specific studies have shown an increased incidence of FD. The clinical presentation varies between classic and late phenotypes, with cardiac involvement being a major concern, particularly in late-onset FD. Purpose: This study aimed to summarize the current knowledge on FD, emphasizing cardiac involvement, diagnostic modalities, and treatment options. Methods: A literature review of relevant studies on FD, including genetics, epidemiology, clinical presentation, diagnostic methods, and treatment options, was conducted. Results: Cardiac manifestations of FD included left ventricular hypertrophy (LVH), heart failure, arrhythmias, and sudden death. Diagnostic approaches such as electrocardiography, echocardiography, and cardiac magnetic resonance imaging play crucial roles in the early detection and monitoring of cardiac involvement. Enzyme replacement therapy (ERT) and emerging treatments have shown promise in managing FD, although challenges remain. Conclusions: FD remains a challenging condition in cardiology, with under-diagnosis being a concern. Early detection and specific therapy are essential to improve patient outcomes. Echocardiography and cardiac MRI are valuable tools for diagnosis and follow-up. Despite the advances in treatment, accessibility remains an issue. More research is needed to deepen our understanding of FD and to improve therapeutic strategies.展开更多

While the introduction of primary percutaneous reperfusion and fibrinolysis has reduced the incidence of these complications to less than 1%. These complications pose significant hemodynamic consequences and necessitate prompt diagnosis. Echocardiography, cardiac magnetic resonance imaging, and computed tomography are valuable tools for establishing an accurate and expedited diagnosis. Consequently, it is imperative to conduct further scientific research to enhance hemodynamic stabilization techniques such as intra-aortic balloon counterpulsation and extracorporeal membrane oxygenation, in addition to exploring new surgical procedures that can reduce mortality resulting from mechanical complications. This article aims to provide a comprehensive review of mechanical complications following myocardial infarction and their correlation with multi-imaging, facilitating a better understanding of these complications.展开更多
Background: Cardiac toxicity is currently defined as a symptomatic decrease in Left Ventricular Ejection Fraction (LVEF) of more than 5% or an asymptomatic decrease of at least 10% to a value of under 50% in repeated ...Background: Cardiac toxicity is currently defined as a symptomatic decrease in Left Ventricular Ejection Fraction (LVEF) of more than 5% or an asymptomatic decrease of at least 10% to a value of under 50% in repeated evaluations on conventional transthoracic echocardiogram (TTE), as well as a Global Longitudinal Strain (GLS) value Aims: To highlight using GLS rather than modified Simpson 2D-LVEF for the evaluation of long-term cardiotoxicity. Case Presentation: The case concerns a 73-year-old female patient with a history of breast cancer chemotherapy and anthracyclines-based therapy who presented symptoms of late cardiac toxicity related to the chemotherapeutic treatment. In the following years, the patient remained asymptomatic with a 2D-LVEF of 48%, dilation of the left atrium was found, and the reservoir phase strain was severely decreased. Conclusion: The preferred method for evaluating cardiovascular complications associated with chemotherapy is the TTE, which is performed prior to the start of treatment, during therapy, and in the follow-up. Myocardial deformation as a predictor of cardiotoxicity allows the identification of subclinical heart failure.展开更多
