Abstract
Pulmonary stenosis caused by calcium deposits on pulmonary valve is relatively rare. We experienced such as case in a 67-year-old man. In March 1992 the patient developed heart failure and internal treatment resulted in remission. Cardiac catheterization study and echocardiography showed a valvular PS. Chest CT and cineangiogram showed the calcified pulmonary valve and annulus.
In July pulmonary valve replacement with a bioprosthetic valve was performed under thoracotomy and ASD was closed by a patch. There were severe calcification of the pulmonary valve, adhered commissure and sclerotic valve ring.
Postoperative course was uneventful, however, the patient developed cardiac tamponade on the 12th day after the operation. Reoperation was carried out. No clear hemorrhage was found and only drainage was done. The patient gradually became worse to develop renal failure and DIC, and died of MOF on 34th postoperative day.
