Residual paravalvular moderate or severe aortic regurgitation (AR) has been an independent risk factor for mortality after transcatheter aortic valve implantation (TAVI). The design of the third gener...
Paravalvular regurgitation is an important complication of mitral valve replacement. Although surgical repair is mostly recommended, it is associated with significant morbidity. On the other hand, per...
Significant paravalvular leak (PVL) occurs in up to 13% of patients after transcatheter aortic valve replacement (TAVR) with a balloon-expandable bioprosthesis. Transcatheter PVL repair has emerged as...
Prostheses attachment is critical in aortic valve replacement surgery, yet reliable prosthetic security remains a challenge. Accurate techniques to analyze prosthetic fixation pressures may enable the...
The SAPIEN 3 (S3; Edwards Lifescience, Irvine, CA, USA) is a new-generation percutaneous aortic valve with better profile, more precise handling and positioning, designed to reduce the risk of post-pr...
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...
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...
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...
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.
A prospective single arm study evaluating feasibility and safety of a catheter-based transapical implantation of the Ventor Embracer™ aortic valve bioprosthesis in patients with severe a...
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.
