Pulmonary Valve Substituted For Aortic  A new technique of homograft valve replacement in which the patient's own pulmonary valve is used to replace a defective aortic or mitral valve was described at the annual Clinical Congress of the American College of Surgeons.The report by Donald N. Ross, MB, ChB, attracted considerable attention among surgeons attending the Chicago meeting.Dr. Ross, one of the pioneers of homograft valve surgery, uses a cadaver aortic valve to replace the excised pulmonary valve. He said the technique may lessen some of the late complications of valve replacement.Late complications of cardiac valve replacement continue to be a problem whether the replacement is homograft or an artificial prosthesis.The embolic complications which occur with the use of an artificial valve are not seen in the homograft. On the other hand, calcification of the homograft has been observed at reoperation or autopsy in patients
