These results suggest that, in this setting, ischaemic preconditioning is mediated, at least in part, by A1 adenosine receptors.

Need of permanent pacemaker implantation after aortic valve replacement seems to be related more to preoperative advanced aortic valve disease rather than pre-existing conducting system abnormalities. An accurate surgical technique for aortic valve replacement probably helps to prevent further impairment of conducting system function requiring early postoperative permanent pacemaker implantation.

Having a bileaflet aortic prosthesis of one size larger did not seem to significantly influence the pattern and the extent of regression of left ventricular hypertrophy after an intermediate period of follow-up.
