Implantation of heart valve prostheses without anticoagulants

Trans-catheter Bioprosthetic Heart Valve Implantation in Iran (Tehran Heart Centre Experience)

Introduction: With the development of interventional cardiology in the world, in addition to coronary and aortic diseases, the treatment of heart valve diseases through catheters has recently begun. The treatment of aortic stenosis (which was only possible with open surgery and valve replacement) was first performed in the world in 2002 by Alain Cribier in France with catheter insertion of the ...

Hancock, and Carpentier-Edwards heart valve prostheses

From 1975 to 1979, 540 patients undergoing valve replacement were entered into a randomized trial and received either a Bjdrk-Shiley (273 patients) or a porcine heterograft prosthesis (initially a Hancock valve [107 patients] and later a Carpentier-Edwards prosthesis [ 160 patients]). Two hundred and sixty-two patients required mitral valve replacement, 210 required aortic valve replacement, 60...

Transapical aortic valve implantation with anatomically oriented prostheses.

Prediction of hemorrhagic and thrombotic events in patients with mechanical heart valve prostheses treated with oral anticoagulants.

BACKGROUND Variability in the intensity of anticoagulant therapy is considered a risk factor for complications, but it is unclear how best to quantify variability. OBJECTIVE We evaluated the association of three methods to measure variability with complications of oral anticoagulant therapy. METHODS We conducted a nested case-control study within a cohort of patients with prosthetic heart v...

Annular injuries following the insertion of heart valve prostheses.

Bowes, V. F., Datta, B. N., Silver, M. D. and Minielly, J. A. (1974). Thorax, 29, 530-533. Annular injuries following the insertion of heart valve prostheses. The clinical presentation and morphological findings in eight cases of annular injury associated with the insertion of prosthetic heart valves are discussed. The lesions presented as a separation of the left atrium and ventricle at the mi...
