title: The application of scanning electron microscopy in the investigation of acute rheumatic valvulitis.
abstract: Four surgically resected cardiac valves received from three female patients showed the presence of acute and chronic rheumatic valvulitis. The material was studied by means of transmission and scanning electron microscopy. This is the first time that there has been an investigation of the ultrastructure in acute rheumatic valvulitis.
