Optimal Oversizing Index Depending on Valve Type and Leakage-Proof Function for Preventing Paravalvular Leakage after Transcatheter Aortic Valve Implantation [PDF]

Journal of Clinical Medicine, 2020
Paravalvular leak (PVL) is an important complication of transcatheter aortic valve implantation (TAVI) and is associated with poor prognosis. We aimed to identify the risk factors for PVL after TAVI including patient (calcium amount or location), device (

A fast in silico model for preoperative risk assessment of paravalvular leakage. [PDF]

Biomech Model Mechanobiol
AbstractIn silico simulations can be used to evaluate and optimize the safety, quality, efficacy and applicability of medical devices. Furthermore, in silico modeling is a powerful tool in therapy planning to optimally tailor treatment for each patient.

Prediction of paravalvular leakage after transcatheter aortic valve implantation. [PDF]

Int J Cardiovasc Imaging, 2015
Significant paravalvular leakage (PVL) after transcatheter aortic valve implantation (TAVI) is related to patient mortality. Predicting the development of PVL has focused on computed tomography (CT) derived variables but literature targeting CoreValve devices is limited, controversial, and did not make use of standardized echocardiographic methods.

Management of Transapical Mitral Paravalvular Leakage Device Closure Complication with Perfect Result

Research in Cardiovascular Medicine
Paravalvular leakage following surgical valve replacement is one of the major complications that have long-term morbidity. The gold standard of treatment was surgery in most literature, but transcatheter procedures showed promising results.

Evaluation of Paravalvular Leakage in Novel Mechanical Heart Valve

Volume 3: 19th International Conference on Advanced Vehicle Technologies; 14th International Conference on Design Education; 10th Frontiers in Biomedical Devices, 2017
We developed a new mechanical heart valve prototype with a unique mechanism for attachment to cardiac tissue. The development of novel prosthetic heart valve systems requires careful assessment of paravalvular leaks — leakage of fluid that takes place between the valve and the cardiac tissue it is attached to.

The Lotus dilemma-respond to paravalvular leakage, but not answering pacemaker implantations? [PDF]

J Thorac Dis, 2017
The treatment of symptomatic aortic valve stenosis has been revolutionized by transcatheter aortic valve replacement (TAVR), evolving from a last resort therapy to the standard treatment of patients at intermediate or high risk for conventional surgery (1,2).

Evaluation of the Transcatheter Aortic Valve Replacement Results in Patients with Borderline Aortic Annulus and the Impact of Under- or Oversizing the Valve

Anatolian Journal of Cardiology, 2023
Background: Optimal valve sizing provides improved results in transcatheter aortic valve replacement. Operators hesitate about the valve size when the annulus measurements fall into borderline area.
