Combined aortic valve replacement and closure of patent ductus arteriosus in the elderly

Two cases of patent ductus arteriosus (PDA) and aortic stenosis are presented. Both were diagnosed at routine cardiac catheterization and significant aortic gradient was concomitantly encountered. The first patient had subacute bacterial endocarditis due to B. cereus infection. Eventually it was proven to be localized on the PDA on the pulmonary artery side. Both patients underwent closure of PDA through endopulmonary closure and aortic valve replacement. Postoperative courses were uneventful. These cases demonstrated the technically easy closure of the PDA in the elderly. The literature has documented only six cases including our two cases.
