Evaluation of Aortic Paravalvular Leak: A Special Reference for Anatomical Localization.

Paravalvular leakage (PVL) remains an unavoidable complication of heart valve surgery and in its severe forms may lead to heart failure and hemolysis. The study aim was to evaluate the echocardiograph...

Procedural Techniques for the Management of Severe Transvalvular and Paravalvular Aortic Regurgitation During TAVR.

Aortic regurgitation (AR) after transcatheter aortic valve replacement (TAVR) is associated with an increased risk of mortality. In severe cases, abrupt hemodynamic changes may occur with a sudden inc...

Transcatheter treatment of 'complex' malfunction of tricuspid valve prosthesis.

A 45-year-old man with Ebstein anomaly of the tricuspid valve, previously submitted for tricuspid valve replacement and plication of the atrialized part of the right ventricle, was referred because of...

New-Onset Hemolytic Anemia after Percutaneous Paravalvular Leak Closure.

Despite being usually clinically silent, paravalvular leak can present with congestive heart failure (CHF) or haemolytic anemia. Here, the case is reported of a paravalvular leak presenting with CHF, ...

Percutaneous Antegrade Trans-Septal Closure of Mitral Paravalvular Leak without Creation of an Arteriovenous Wire Loop in Patients with Coexistent Mechanical Aortic Valve.

Various approaches such as antegrade trans-septal, retrograde transfemoral and transapical techniques have been used to close mitral paravalvular leak (PVL) in patients with an aortic prosthesis. Duri...

The German Plug - Registry

In approximately 10-15% of all patients after surgical or interventional heart valve replacement, flapping defects appear as complications in the long-term course, so-called paravalvular /...

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

To evaluate the performance, efficacy and safety of the percutaneous implantation of the CoreValve® prosthetic aortic valve in patients with severe symptomatic native aortic valve stenosi...

On-X Aortic Prosthetic Heart Valve Low Dose Warfarin Post Approval Clinical Registry Study

The purpose of the proposed study is to assess the occurrence of bleeding, valve-related thromboembolism and valve thrombosis with the On-X Aortic Prosthetic Heart Valve when targeted at a...

Transfemoral Replacement of Aortic Valve With HLT MeriDIAN Valve Feasibility Trial CANADA

To evaluate the safety and performance of the HLT System in patients with severe aortic stenosis who present at high risk for aortic valve replacement surgery.

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.

Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.

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.
