Transcatheter aortic valve‐in‐valve implantation of a corevalve in a degenerated stenotic sapien heart valve prosthesis

Catheterization and Cardiovascular Interventions, 2013
Treatment options for re‐stenotic aortic valve prosthesis implanted by transcatheter technique have not been evaluated systematically. We describe the case of a 75‐year‐old dialysis patient who was treated by transcatheter aortic valve implantation 3.5 years ago and now presented with severe stenosis of the percutaneous heart valve.

Thirty-Year Results After Implantation of the Björk-Shiley Convexo-Concave Heart Valve Prosthesis

The Annals of Thoracic Surgery, 2014
Modifications of the Björk-Shiley valve prosthesis have shown good long-term results. The convexo-concave model, however, was recalled 27 years ago because of a propensity for breakage due to outlet strut fracture. The objective of this study is to describe the 30-year outcome after implantation of the Björk-Shiley convexo-concave mechanical heart ...

Intraoperative Transesophageal and Postoperative Transthoracic Echocardiographic Evaluation of a Mechanical Heart Valve Prosthesis Implanted at Aortic Position

Journal of Cardiothoracic and Vascular Anesthesia, 2018
The aims of this study were to evaluate the intraoperative transesophageal echocardiographic (iTEE) characteristics and Doppler flow profile of aortic Chitra heart valve prosthesis (CHVP) under stable hemodynamic and loading conditions, and to compare and correlate the iTEE data with the postoperative transthoracic echocardiography (TTE) data obtained ...

In vitro study of valve-in-valve performance with the CoreValve self-expandable prosthesis implanted in different positions and sizes within the Trifecta surgical heart valve

Computer Methods in Biomechanics and Biomedical Engineering, 2015
The valve-in-valve (VinV) percutaneous procedure is a valuable alternative for the treatment of failed bioprosthetic surgical heart valves (SHV) in high-risk patients (Dvir et al. 2014).

Heart Valve Replacement with the St. Jude Medical® Valve Prosthesis: Long-Term Experience in 743 Patients Receiving Valve Implants in Switzerland [PDF]

, 1989
From November 1978 to June 1986, 743 patients received 828 ST. JUDE MEDICAL® valves (SJM) at the University Clinics of Basel, Berne, and Lausanne, Switzerland. There were 445 men and 298 women, with a mean age of 57 years (range 1–83 years), who were followed for a mean of 2.6 years (22,768 patient-months).

Transfemoral transcatheter aortic valve implantation in the presence of a mechanical mitral valve prosthesis using a dedicated TAVI guidewire: utility of a patient-specific three-dimensional heart model

Cardiovascular Intervention and Therapeutics, 2016
An 82-year-old woman with severe aortic stenosis was referred. She had previously undergone mitral valve replacement. We planned transcatheter aortic valve implantation (TAVI) with transfemoral approach. We planned to use the Safari-dedicated TAVI guidewire. No studies have reported clinical application of the dedicated TAVI guidewire in a patient with

First percutaneous implantation of a completely tissue-engineered self-expanding pulmonary heart valve prosthesis using a newly developed delivery system: a feasibility study in sheep

Cardiovascular Intervention and Therapeutics, 2016
In a European consortium, a decellularized tissue-engineered heart valve (dTEHV) based on vessel-derived cells, a fast-degrading scaffold and a self-expanding stent has been developed. The aim of this study was to demonstrate that percutaneous delivery is feasible.

Mid-term results after heart valve replacement with the CarboMedics bileaflet prosthesis: experience with 785 implants.

Giornale italiano di cardiologia, 1999
The aim of the study was to evaluate our clinical experience with the CarboMedics Heart Valve Prosthesis.Between October 1991 and December 1997, six hundred seventy-two consecutive patients (361 men, 54%; 311 women, 46%; mean age 57 +/- 12 year, range 6-73 years) underwent mechanical valve implantation at the Division of Cardiac Surgery of the ...

[Iron deficiency following implantation of a heart valve prosthesis].

Zeitschrift fur Kardiologie, 1976
In 44 patients with single or multiple valvular protheses of the heart, the problem of secondary iron deficiency due to mechanical hemolysis was investigated. In 17 cases, elevated serum transferrin values were noted, compared to elevated serum iron levels in only 6 cases.

Expanding the use of total mitral valve preservation in combination with implantation of the CarboMedics heart valve prosthesis.

The Journal of cardiovascular surgery, 1999
Preservation of the mitral valve and subvalvular apparatus was introduced into the clinic in the early sixties, but for two decades the standard technique for mitral valve replacement included excision of both leaflets and their attached chordae tendineae. Lately, increased emphasis has again been placed on retention of the mitral subvalvular apparatus
