Abstract:
This paper reports on a case in which a heavily-calcified so-called “porcelain aorta” (including the ductus arteriosus) was observed, together with a patent ductus arteriosus and aortic stenosis associated with a bicuspid aortic valve. A 76-year-old man had been referred to our hospital on a diagnosis of aortic stenosis. Since angiography revealed slight contrast in an area on the right side of the heart, echocardiography was performed and revealed patent ductus arteriosus. Severe circumferential calcification of the ascending aorta and aortic arch was observed on CT scans. Almost no calcification was observed in other areas. Aortic valve replacement and closure of the ductus arteriosus (transpulmonary approach) were performed by means of a balloon to temporarily occlude the aorta, as surgical clamping was impossible due to calcification. Hypothermic systemic perfusion and antegrade selective cerebral perfusion were used. The postoperative progress of the patient was good. Bicuspid aortic valve and patent ductus arteriosus are highly likely to be present in combination in cases of congenital cardiac anomaly, and it is therefore necessary to be particularly attentive when diagnosing such cases. It was considered that our patient, an adult suffering patent ductus arteriosus, was a rare case in which the calcified ductus arteriosus was observed and the calcification had spread to the ascending aorta.
