Under ordinary conditions musculofascial cross-grafts made between pairs of rabbits of the same strain and species elicited classical host-homograft tissue interactions. When the cross-grafting was done 7 to 10 days after exchange transfusions leading to introduction of about 40 per cent of foreign blood, the classical host-homograft reaction failed to develop. In its stead there was an harmoni...
BACKGROUND Aortic valve replacement in a patient with an aortic homograft can be very challenging, especially when concomitant mitral valve surgery needs to be performed. CASE PRESENTATION We report a case of implantation of a sutureless aortic valve bioprosthesis combined with mitral valve replacement in a patient with a severely calcified aortic homograft where conventional valve replacemen...
We thank Dr Dainese from Milan for his comments [1], although we are a little surprised by his first comment. As was already stated in our paper [2], our first implantation was done on 16 December 2008, our second implantation was done in January 2009 and Dainese [3] performed an implantation on 3 February 2009. Nevertheless, we would like to congratulate Dr Dainese and his colleagues and we ac...
BACKGROUND The pulmonary autograft operation (the Ross procedure) involves excision of a portion of the right ventricular (RV) outflow tract, prolonged cross-clamp times, and insertion of a pulmonary homograft. There is concern about the effect of such operations on right ventricular function. METHODS AND RESULTS Twenty-five patients undergoing either pulmonary autograft or homograft replacem...
OBJECTIVE Given the shortage of small-sized cryopreserved homografts for right ventricle (RV) to pulmonary artery (PA) reconstructions, more readily available larger-sized homografts can be used after size reduction by bicuspidalization. The aim of our study was to determine and compare function over time of standard and bicuspidalized homografts in infants younger than 12 months, including pat...
