12 Conclusions The sinuses of Valsalva rarely dilate significantly after AVR and aortic repairThe sinuses of Valsalva rarely dilate significantly after AVR and aortic repair Separate valve and graft remains a reasonable option in the absence of significant root dilatationSeparate valve and graft remains a reasonable option in the absence of significant root dilatation The ascending aorta remains at risk of late dilatation if treated with aortoplastyThe ascending aorta remains at risk of late dilatation if treated with aortoplasty
