Paravalvular aortic regurgitation (PAR) negatively affects the prognosis after transcatheter aortic valve replacement (TAVR) with dramatically increased morbidity and mortality in patients with more than mild PAR. Because transcatheter heart valves are implanted in a sutureless fashion using oversizing to anchor the prosthesis stent frame at the level of the virtual aortic annulus, stent frame ...

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 ...

The first mechanical heart valve prosthesis, designed by Dr Charles Hufnagel, was implanted to the descending aorta of a 30-year-old woman with severe aortic regurgitation in 1952.1 Eight years after the initial successful prosthetic valve implantation, Dr Harken sutured a prosthetic valve (Starr Edwards Valve) to the aortic annulus after removing the diseased native valve. During the ensuing y...

Prosthetic valve re-operation has greater mortality and morbidity than primary valve replacement. By recognition of factors influencing on causes of redo operation and preoperative survival, one can select appropriate prosthesis at primary valve replacement and when operation performed at appropriate time, surgical risk can be reduced.Methods and Materials: Two hundred patients that underwent p...

OBJECTIVES This study sought to evaluate the use of the Direct Flow Medical (DFM) transcatheter heart valve (Direct Flow Medical, Santa Rosa, California) for the treatment of noncalcific pure aortic regurgitation (AR). BACKGROUND The treatment of noncalcific AR has remained a relative contraindication with transcatheter heart valves due to challenges in anchoring devices in the absence of cal...
