Repositionable self-expanding aortic bioprosthesis

Expert Review of Medical Devices, 2017
Transcatheter aortic valve implantation/replacement (TAVI or TAVR) has been established as a first line therapy in patients with symptomatic severe aortic stenosis (AS) at high or prohibitive surgical risk and as an alternative in elderly patients with intermediate surgical risk.

Thromboembolism with low profile bioprosthesis

European Heart Journal, 1984
Low profile bioprosthesis late follow-up indicates a low incidence of thromboembolism. For the entire series of 415 consecutively operated patients (rigid and flexible stents) the actuarial probability of freedom at 6 years is 90.3% (87.8% for MVR and 92.27% for AVR and 95.24% for MVR + AVR).

Balloon valvoplasty of mitral bioprosthesis

International Journal of Cardiology, 1991
We describe a case of percutaneous balloon valvoplasty of a stenotic Ionescu-Shiley mitral bioprosthesis with the help of an original emboli-protecting device. The procedure reduced diastolic gradient from 29 to 9 mmHg. The calculated area of the orifice increased from 0.7 to 1.7 cm2.

Conduit-on-valve replacement of a degenerated mitral bioprosthesis with a bioprosthesis

The Annals of Thoracic Surgery, 2003
Explantation of a degenerated mitral bioprosthesis with reimplantation of a new bioprosthesis is time-consuming and can be associated with several life-threatening complications. We developed a technique to simplify this procedure and avoid the complications by attaching a new bioprosthesis supported by a pericardium-covered Dacron tube to the intact ...

Fracture of small Mitroflow® aortic bioprosthesis following valve‐in‐valve transcatheter aortic valve replacement with ACURATE neo valve—From bench testing to clinical practice

Catheterization and cardiovascular interventions, 2020
Valve‐in‐valve (ViV) transcatheter procedures have emerged as a feasible, less‐invasive treatment option for bioprosthetic structural valve deterioration.

Long-term results and durability of the CoreValve transcatheter aortic bioprosthesis: outcomes beyond five years.

EuroIntervention, 2019
AIMS The aim of this study was to determine the long-term outcomes of high-risk patients who underwent transcatheter aortic valve implantation (TAVI) with the third-generation CoreValve device, according to the 2017 EAPCI/ESC/EACTS definition of valve ...

MYOCARDIAL BIOPROSTHESIS: MIMICKING NATURE

Drugs of the Future, 2013
Cardiac diseases of ischemic origin are threatening clinical conditions characterized by enlarged dysfunctional hearts and the risk of sudden death, with myocardial infarction being the most common disease. The only definitive treatment at present is a cardiac transplant, but new therapeutic approaches, such as the implantation of isolated cells with ...

Repeat replacement of aortic valve bioprosthesis

The Annals of Thoracic Surgery, 1995
We describe a safe and simple technique for replacing an aortic valve bioprosthesis in a patient who also had a previously implanted ascending aortic graft and multiple coronary artery bypass grafts. This method allows for isolated valve replacement without removal of the ascending aortic graft or alteration of the coronary artery bypass graft ...

The New Labcor-Santiago Pericardial Bioprosthesis

Journal of Cardiac Surgery, 1991
The Labcor-Santiago pericardial valve has been designed to minimize mechanical stress and to avoid abrasion wear, at the same time preserving the concept of mounting the pericardium outside the posts for full orifice opening. The new design has preserved the traditional superior hemodynamic performance of pericardial valves, avoiding abrasion by ...

The INTACT Bioprosthesis - Early Results

Journal of Cardiac Surgery, 1988
The INTACT (previously Xenotech) valve incorporates three major departures from previously available bioprostheses. The following innovations are aimed at reducing calcification and improving durability: (1) the stent has a high profile configuration and the sinuses are deeply excavated.
