Congenital aneurysms located in the sinuses of Valsalva typically expand and may eventually rapture into the right atrium or ventricle. In 1957, Dr Lillehei and colleagues reported 3 patients who underwent successful repair of raptured sinus of Valsalva aneurysms at the University of Minnesota. This achievement required an accurate understanding of the pathology and anatomy of sinus of Valsalva aneurysms, as well as the successful application of surgical science to solve the problems posed by the repair of these aneurysms. Doctor Lillehei's article is a classic in the field of cardiothoracic surgery and is now reviewed 36 years after its publication. © 1993.
