BACKGROUND: The acute adaptation of the nitinol-based stent frame self expandable valve to the aortic root after deployment is poorly understood. Accordingly, this study aimed to assess the occurrence, degree and determinants of acute adaptation of the nitinol-based stent frame self-expandable valves after implantation. METHODS: This is a single-site prospective registry including patients undergoing transcatheter aortic valve replacement (TAVR) with a widely used second-generation nitinol-based self-expandable device (Evolut R, Medtronic, Minneapolis, Minnesota, USA)...

BACKGROUND: Although sex disparities between patients with acute myocardial infarction are well known, the data regarding sex differences among symptomatic patients with acute chest pain (ACP) are limited. METHODS: We retrospectively evaluated the records of 1000 consecutive patients with ACP and hospitalized in a tertiary medical center chest pain unit (CPU). Patients were divided according to sex. The primary outcome was defined as a composite end point of readmission because of chest pain, incidence of acute coronary syndrome, revascularization, and death at 90 days and 1 year...

BACKGROUND: Arterial stiffness indices are used to assess the material properties of the arterial wall and are associated with cardiovascular events. Aortic stenosis (AS) is commonly caused by degenerative calcification and can be associated with increased arterial stiffness. However, the clinical implications of arterial stiffness indices in AS patients before and after treatment are unknown. METHODS: This single-center observational study enrolled 150 consecutive patients who underwent transcatheter aortic valve implantation (TAVI) for severe AS...

BACKGROUND: Preparticipation screenings have been conceived for the potential to prevent sudden cardiac death in young athletes by early identification of hidden cardiac diseases. Commonly used protocols include family history collection, physical examination, and resting electrocardiogram. Transthoracic echocardiography has been hypothesized to have a primary role in the preparticipation screening. AIMS: The present study aimed to evaluate the additional role of echocardiogram in identifying cardiovascular abnormalities that might be undetected by commonly used preparticipation screening...

AIMS: Data regarding the pulmonary hypertension (PH)-related mortality and relative trends in the Italian population remain scant. We sought to assess the PH mortality rates and relative trends among the Italian population between 2005 and 2017. METHODS: Data regarding the cause-specific mortality and population size by sex in 5-year age groups were extracted from the WHO global mortality database. The age-standardized mortality rates, with relative 95% confidence intervals (CIs), also stratified by sex, were using the direct method...

AIMS: Inflammation in the epicardial adipose tissue (EAT) is a contributor to atrial fibrillation. Studies have reported that sodium glucose co-transporter 2 inhibitor (SGLT2i) can alleviate EAT inflammation. However, the mechanism remains elusive. This study aims to investigate the molecular mechanism of SGLT2i in reducing EAT inflammation and to explore the effects of SGLT2i on atrial fibrosis in atrial fibrillation. METHODS: Sprague-Dawley rats were injected with angiotensin II to induce atrial fibrillation and randomly assigned to receive SGLT2i (n = 6) or vehicle (n = 6)...

BACKGROUND AND AIMS: High epicardial adipose tissue (EAT) attenuation is a key characteristic of adipose tissue dysfunction and associated with coronary artery disease (CAD). As little is known about the modulation of EAT attenuation by metabolic disorders, we investigated the association between EAT attenuation and CAD risk factors, CAD presence and CAD severity in type 2 diabetes mellitus (T2DM) patients. METHODS: We included 276 inpatients with T2DM and 305 control patients with normal glucose metabolism (NGM), who underwent cardiac computed tomography angiography (CCTA) and coronary artery calcium (CAC) scoring...

Stent dislodgement during angioplasty is a rare but potentially fatal complication if not properly managed. We described a case of an elderly man who had previously undergone coronary angioplasty and now presented with an inferior wall myocardial infarction and required emergency angioplasty. Because of the loss of antegrade flow during the procedure, the proximal lesion was stented first. Undeployed stent was dislodged into proximal stent during distal stent deployment through proximal stent. This complication was addressed by crushing the undeployed stent and deploying another stent to secure the crushed stent to the arterial wall...

AIMS: Recent studies suggest an association between epicardial adipose tissue (EAT) and atrial fibrillation. The aim of the study is to evaluate the quantitative and qualitative characteristics of EAT in relation to atrial fibrillation burden after coronary artery bypass graft (CABG). METHODS: This prospective single-centre study included patients undergoing CABG. The patients underwent transthoracic echocardiography and collection of a bioptic sample containing right appendage and EAT during CABG for histological characterization...

As our understanding of atherosclerotic vascular injury continues to evolve, so should our diagnostic approaches. Emerging data have recently challenged our basic understanding in linking ischemia to its adverse outcomes as well as the need for invasive testing for both diagnosis and treatment. The advent of coronary computed tomography in providing improved visualization of coronary arteries has led to the identification of both subclinical atherosclerosis and high-risk coronary lesions. Recognition of asymptomatic coronary artery disease (CAD) with objective localization of subclinical coronary atherosclerosis improves atherosclerotic cardiovascular risk assessment and allows healthcare providers to take effective primary prevention measures...
