High-sensitivity troponin I concentrations are a marker of an advanced hypertrophic response and adverse outcomes in patients with aortic stenosis [PDF]

, 2014
Aims: High-sensitivity cardiac troponin I (cTnI) assays hold promise in detecting the transition from hypertrophy to heart failure in aortic stenosis.

Biological niches within human calcified aortic valves. Towards understanding of the pathological biomineralization process [PDF]

, 2015
Despite recent advances, mineralization site, its microarchitecture, and composition in calcific heart valve remain poorly understood. A multiscale investigation, using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ...

Imaging of Low-Gradient Severe Aortic Stenosis

JACC: Cardiovascular Imaging, 2013
Although most patients with severe aortic stenosis (AS) have high peak velocity and mean transvalvular gradient, there is a subset of patients with low-flow, low-gradient severe AS (LGSAS). Assessment and management of such patients can be difficult and dobutamine echocardiography has been recommended to distinguish those with pseudo-AS (low calculated

Aortic Stenosis Suspected to Be Severe Despite Low Gradients [PDF]

Circulation: Cardiovascular Imaging, 2014
The American College of Cardiology/American Heart Association and European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines generally recommend aortic valve replacement (AVR) in patients with severe aortic stenosis (AS) who have symptoms, have left ventricular (LV) systolic dysfunction, or undergo coronary artery bypass

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.

Arrhythmic risk in elderly patients candidates to transcatheter aortic valve replacement. predicative role of repolarization temporal dispersion [PDF]

, 2019
Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities ...

Low “gradient”, low flow aortic stenosis [PDF]

Heart, 2006
Aortic stenosis is thought to have a long, asymptomatic latent phase during which the risk of sudden death is low. In fact symptoms can be revealed by treadmill exercise in a large proportion of apparently asymptomatic patients.1 Patients may limit exercise to avoid symptoms or may fail to recognise the presence of exertional breathlessness or ascribe ...

Comprehensive assessment of the aortic valve in critically ill patients for the non-cardiologist. Part I: Aortic stenosis of the native valve

Anaesthesiology Intensive Therapy, 2021
Aortic stenosis (AS) causes left ventricular outflow obstruction. Severe AS has major haemodynamic implications in critically ill patients, in whom increased cardiac output and oxygen delivery are often required.

Surgery for severe aortic stenosis with low transvalvular gradient and poor left ventricular function – a single centre experience and review of the literature

Journal of Cardiothoracic Surgery, 2007
Background A retrospective comparative study was designed to determine whether the transvalvular gradient has a predictive value in the assessment of operative outcome in patients with severe aortic stenosis and poor left ventricular function.
