This paper reports on a case in
which a heavily-calcified so-called gporcelain aortah (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.
