Abstract:
We describe two cases of aortic regurgitation with dove-coo murmur that required aortic valve replacements. In the first case, there were three small perforations of the cusps, two in the noncoronary cusp and one in the right coronary cusp. The cause of the cusp perforations was unclear. In the second case, there were two perforations of the cusps, one in the left coronary cusp and another small one in the right coronary cusp, along with a subannular pseudoaneurysm. The cause of the cusp perforations was an infective endocarditis. Before 1955, aortic regurgitations with dove-coo murmur were mostly reported to be originated by retroversion of the valve cusps due to syphilis. After 1960, syphilis was replaced by various diseases that bring about perforations, tears and retroversions of the cusps. The condition which is concerned in the development of the dove-coo murmur is that the aortic valve cusps have lesions without calcification and preserve the flexibility.
