Aortic Valve Replacement for Calcified Aortic Valves

Aortic valve replacement with homograft and autograft valves. Performance of 615 valves over 15 years.

Homograft valve replacement of the diseased aortic valve with a homologous aortic valve inserted in the sub-coronary position was first performed in July 1962 (Ross 1962). The procedure of transferring the patients autologous pulmonary valve to the aortic position has been used since 1967 (Ross 1967). The long term performance of homograft vaives has not been regarded as satis facrory in some c...

Transcatheter pulmonary valve replacement: valves, techniques of implantation and outcomes

Transcatheter pulmonary valve replacement has changed the way we approach congenital and structural heart disease. In patients with a conduit between the right ventricle and pulmonary artery or a bioprosthetic pulmonary valve, there will eventually be pulmonary valve dysfunction. This leads to right ventricular failure and possibly arrhythmias. Due to prior operations and the comorbid condition...

Is a stentless aortic valve superior to conventional bioprosthetic valves for aortic valve replacement?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether a stentless valve is superior to conventional stented valves when tissue aortic valve replacement is performed. Altogether more than 515 papers were found using the reported search, of which 16 represented the best evidence to answer the clinical question. The authors, jou...

Failing stentless aortic valves: redo aortic root replacement or valve in a valve?

OBJECTIVES Reoperation for failing stentless aortic valve replacement is a technically demanding procedure that has traditionally been tackled in one of two ways: either root replacement or the more conservative option of implanting a stented valve within the valve. We sought to determine the relative operative risks, follow-up status and medium to long-term survival of these two methods. MET...
