Paravalvular Leak Leading to Severe Aortic Valve Regurgitation after TAVI: Percutaneous Closure Strategy.

Regurgitation due to a paravalvular leak (PVL) is a complication that may affect patients undergoing surgical mechanical or bioprosthetic heart valve replacement. PVL can also occur after transcathete...

Influence of baseline ejection fraction on the prognostic value of paravalvular leak after transcatheter aortic valve implantation.

Moderate or severe paravalvular leak (PVL≥moderate) after transcatheter aortic valve implantation (TAVI) is associated with poor outcomes. The aim of this study was to assess whether the baseline ej...

Transcatheter, valve-in-valve transapical aortic and mitral valve implantation, in a high risk patient with aortic and mitral prosthetic valve stenoses.

Transcatheter valve implantation continues to grow worldwide and has been used principally for the nonsurgical management of native aortic valvular disease-as a potentially less invasive method of val...

Successful implantation of a second-generation aortic valve in severe aortic regurgitation secondary to a traumatic cusp lesion.

A 67-year-old man with a dilated cardiomyopathy and severe aortic regurgitation (AR) secondary to a traumatic cusp lesion was referred to our institution because of progressive worsening of dyspnea. A...

Prosthetic Valve Endocarditis Five Months following Transcatheter Aortic Valve Implantation and Review of Literature.

There are only a few cases of prosthetic valve endocarditis (PVE) following transcatheter aortic valve implantation (TAVI) reported in the literature. Though not very frequent, this is a serious conce...

Minimally Invasive Aortic Valve Replacement Versus Conventional Aortic Valve Replacement. a Long Term Registry

The aim of the present study is to assess in a "real life" caselist the outcome of three different surgical approches for isolated aortic valve surgery in terms of surgery times, morbidity...

CoreValve® System Australia/New Zealand Clinical Study

Conservative Aortic Valve Surgery for Aortic Insufficiency and Aneurysms of the Aortic Root. CAVIAAR

The primary objective of the CAVIAAR study is to prove that aortic valve sparing is associated with a 50% increase of 3 years-survival rate without increased mortality or serious increased...

Assessment and Cardiovascular Rehabilitation in Patients With Severe Aortic Stenosis

This study will evaluate hemodynamic and functional changes resulting from valve intervention in patients with severe aortic stenosis undergoing valve replacement (AVR) or transcatheter ao...

Medical and Biotech [MESH] Definitions

The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.

Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).

A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

A condition caused by underdevelopment of the whole left half of the heart. It is characterized by hypoplasia of the left cardiac chambers (HEART ATRIUM; HEART VENTRICLE), the AORTA, the AORTIC VALVE, and the MITRAL VALVE. Severe symptoms appear in early infancy when DUCTUS ARTERIOSUS closes.
