How to perform and evaluate a myocardial perfusion imaging by computed tomography.

Stress computed tomography perfusion (CTP) delivers a comprehensive evaluation of both the anatomical and functional aspects in a single examination. It stands out as the only non-invasive technique capable of quantifying coronary stenosis and assessing its functional impact, offering a consolidated diagnostic and management approach for patients with confirmed or suspected coronary artery disease (CAD). This very practical review ('How to.

Prognostic value of myocardial computed tomography-derived extracellular volume in severe aortic stenosis requiring aortic valve replacement: a systematic review and meta-analysis.

Computed tomography (CT)-derived extracellular volume (ECV) fraction is a non-invasive method to quantify myocardial fibrosis. Evaluating CT-ECV during aortic valve replacement (AVR) planning CT in severe aortic stenosis (AS) may aid prognostic stratification. This meta-analysis evaluated the prognostic significance of CT-ECV in severe AS necessitating AVR.

Vitamin D: A Bridge between Kidney and Heart.

Chronic kidney disease (CKD) and cardiovascular disease (CVD) are highly prevalent conditions, each significantly contributing to the global burden of morbidity and mortality. CVD and CKD share a great number of common risk factors, such as hypertension, diabetes, obesity, and smoking, among others. Their relationship extends beyond these factors, encompassing intricate interplay between the two systems.

The Role of Multimodality Imaging Approach in Acute Aortic Syndromes: Diagnosis, Complications, and Clinical Management.

Acute aortic syndromes are life-threatening conditions with high morbidity and mortality. The principal pathological feature is acute wall damage with possible evolution towards aortic rupture. Accurate and timely diagnosis is mandatory to avoid catastrophic consequences.

Clinical Risk Prediction in Patients With Left Ventricular Myocardial Noncompaction.

Background: Left ventricular noncompaction (LVNC) is a heterogeneous entity with uncertain prognosis.

Objectives: This study sought to develop and validate a prediction model of major adverse cardiovascular events (MACE) and to identify LVNC cases without events during long-term follow-up.

Methods: This is a retrospective longitudinal multicenter cohort study of consecutive patients fulfilling LVNC criteria by echocardiography or cardiovascular magnetic resonance.

Aortic Branch Aneurysms and Vascular Risk in Patients With Marfan Syndrome.

Background: Aortic branch aneurysms are not included in the diagnostic criteria for Marfan syndrome (MFS); however, their prevalence and eventual prognostic significance are unknown.

Objectives: The goal of this study was to assess the prevalence of aortic branch aneurysms in MFS and their relationship with aortic prognosis.

Methods: MFS patients with a pathogenic FBN1 genetic variant and at least one magnetic resonance or computed tomography angiography study assessing aortic branches were included.

Multi-Centre, Multi-Vendor and Multi-Disease Cardiac Segmentation: The M&Ms Challenge.

The emergence of deep learning has considerably advanced the state-of-the-art in cardiac magnetic resonance (CMR) segmentation. Many techniques have been proposed over the last few years, bringing the accuracy of automated segmentation close to human performance. However, these models have been all too often trained and validated using cardiac imaging samples from single clinical centres or homogeneous imaging protocols.

Cardiac Imaging in Anderson-Fabry Disease: Past, Present and Future.

Anderson-Fabrydisease is an X-linked lysosomal storage disorder caused by a deficiency in the lysosomal enzyme α-galactosidase A. This results in pathological accumulation of glycosphingolipids in several tissues and multi-organ progressive dysfunction. The typical clinical phenotype of Anderson-Fabry cardiomyopathy is progressive hypertrophic cardiomyopathy associated with rhythm and conduction disturbances.

Leaflet fusion length is associated with aortic dilation and flow alterations in non-dysfunctional bicuspid aortic valve.

Objective: Bicuspid aortic valve (BAV), the most common congenital valve defect, is associated with increased risk of aortic dilation and related complications; however, current risk assessment is not effective. Most of BAV have three leaflets with a fusion between two of them of variable length. This study aimed to ascertain whether the extent of leaflet fusion (often called raphe) is related to aortic dilation and flow abnormalities in BAV with no significant valvular dysfunction.

Atrial Fibrillation, Cancer and Echocardiography.

Nonvalvular atrial fibrillation (AF) is a relatively frequent arrhythmia in cancer patients; it is possibly due to direct effect of cancer or consequence of cancer therapies. AF creates important problems for both therapeutic management and prognosis in cancer patients. The anticoagulation of cancer patients presenting AF is a main issue because of the difficult balance between thromboembolic and bleeding risks, both elevated in this clinical setting.

Prognostic Value of Hormonal Abnormalities in Heart Failure Patients.

The model used to explain the pathophysiologic substrate and progressive worsening in chronic heart failure (CHF) is based on the hyperactivity of renin-angiotensin-aldosterone system and adrenergic pathway. Although the neurohormonal medical approach has many advantages, it has several pitfalls, as demonstrated by high rates of CHF mortality and hospitalization. A growing body of evidence has led to the hypothesis that CHF is a multiple hormone deficiency syndrome, characterized by a reduced anabolic drive that has relevant functional and prognostic implications.

Sex-specific echocardiographic reference values: the women's point of view.

: Clinical presentation, diagnosis and outcomes of cardiac diseases are influenced by the activity of sex steroid hormones. These hormonal differences explain the later development of heart diseases in women in comparison with men and the different clinical picture, management and prognosis. Echocardiography is a noninvasive and easily available technique for the analysis of cardiac structure and function.

Nuclear imaging in detection and monitoring of cardiotoxicity.

Cardiotoxicity as a result of cancer treatment is a novel and serious public health issue that has a significant impact on a cancer patient's management and outcome. The coexistence of cancer and cardiac disease in the same patient is more common because of aging population and improvements in the efficacy of antitumor agents. Left ventricular dysfunction is the most typical manifestation and can lead to heart failure.
