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...
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...
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...
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...
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, ...
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.
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.
