Homograft valve replacement for aortic valve disease.
Our experience with homograft replacement of the aortic valve now includes 175 patients operated on over a period of almost three years, and we have come to aceept this method as the best surgical treatment for aortic incompetence and for calcific aortic stenosis. As others continue to use a ball valve prosthesis, it is important to analyse the results with the homograft valve, paying particula...
متن کاملTransplantation of human homograft aortic valve.
We report the correction of aortic regurgitation by the insertion of a homograft aortic valve. The valve had been stored in buffered formaldehyde for six months, and this technique of preservation is the purpose of this communication. Formaldehyde in acetate buffer for the preservation of valve tissue was suggested to us by Lord Brock (1962), and this report of its use is believed to be the fir...
متن کاملHomograft - the optimal aortic valve substitute?
valvuloplasty can be performed safely and with satisfactory results in over 85% of these patients. It is also possible that repeat PMV can be performed in these patients with acceptable risks and results. In our own single centre experience in about 390 procedures repeat percutaneous balloon valvuloplasty was performed in 17 cases (mean age 65 13 years) without any increase in the rate of acute...
متن کاملTransaortic valve-in-valve implantation after previous aortic root homograft.
Catheter-based valve implantation techniques are becoming a viable option in various clinical situations to replace difficult redo open heart surgical procedures. This is a report of a first, to our knowledge, successful valve-in-valve (VinV) transcatheter aortic valve implantation (TAVI) into a homograft through the transaortic (TAo) access route using an Edwards SAPIEN valve prosthesis (Edwar...
متن کاملHomograft Aortic Valve Replacement in Aortic Incompetence and Stenosis.
The surgery of aortic incompetence and calcific aortic stenosis has made disappointing progress, chiefly because of the need for partial or total valve replacement in many of these patients and the technical problems inherent in designing an artificial valve. In rheumatic aortic incompetence it is now fairly clear that total replacement of the valve is almost always required (McGoon, Mankin, an...
