Sev­en­teen ­years ­after cor­rec­tive sur­gery for a ­double ­outlet ­right ven­tricle and pul­mo­nary sten­osis, a 30-­year-old ­patient was ­admitted for reop­er­a­tion for a crit­ical sten­osis of a por­cine-­valved ­Dacron® con­duit ­between the ­right ven­tricle and pul­mo­nary ­artery. A ­residual ven­tric­ular ­septal ­defect was ­present. Induc­tion of ­anaesthesia ­resulted in an inad­e­quate pul­mo­nary ­flow and uncon­trol­lable ven­tric­ular arrhyth­mias. At ­autopsy the con­duit ­showed a dis­sec­tion ­between the con­duit ­wall and the ­peel for­ma­tion, ­leaving a ­residual ­lumen ­with a diam­eter of ­less ­than a ­third of the orig­inal. ­Patients ­with a ­right ­sided bio­pros­thetic ­valved con­duit ­must be eval­u­ated reg­u­larly and oper­ated ­before the sten­osis ­becomes crit­ical.
