European multicenter experience with valve-sparing reoperations after the Ross procedure

Reoperations after the Ross procedure.

Spectrum and outcome of reoperations after the Ross procedure.

BACKGROUND Proposed advantages to the Ross procedure included presumed increased freedom from reoperation and simpler reoperation for pulmonary conduit replacement if needed. It is increasingly apparent, however, that reoperations are frequent after the Ross procedure and that when required, they may be more complex than previously thought. METHODS AND RESULTS Between September 1991 and Augus...

Reoperations after paediatric Ross operation.

not good because of the recurrent inflammatory disorder. You cannot preserve. Dr Hraska: Okay. Is mechanical aortic valve replacement only, without root replacement, justifiable when the long-term future of the neoaortic root is unclear? Can you comment on that? Dr Alsoufi: This is definitely a good question, and I am already trying to get echocardiograms in those patients who had the aortic va...

Does histocompatibility affect homograft valve function after the Ross procedure?

BACKGROUND Homograft valves have been shown to be immunogenic, but it is unknown whether this affects valve function. Therefore, we prospectively studied the degree of histoincompatibility (defined as the number of human leukocyte antigen [HLA] mismatches between valve donor and recipient) and the response of the recipient (measured by antibodies against HLA) in relation to echocardiographic pa...

Autograft regurgitation and aortic root dimensions after the Ross procedure: the German Ross Registry experience.

BACKGROUND Autograft regurgitation and root dilatation after the Ross procedure is of major concern. We reviewed data from the German Ross Registry to document the development of autograft regurgitation and root dilatation with time and also to compare 2 different techniques of autograft implantation. METHODS AND RESULTS Between 1990 and 2006 1014 patients (786 men, 228 women; mean age 41.2+/...
