Ruptured Aneurysm of Anterior Mitral Leaflet in Aortic Valve Infective Endocarditis

Mini‐ We report the case of a 71‐year‐old man admitted with acute heart failure and suspicion of infective endocarditis (IE). Three‐dimensional transesophageal echocardiography (3DTEE) showed ruptured aneurysm of anterior mitral leaflet (AAML) in scallop A2 with severe mitral regurgitation and perforation of right and noncoronary aortic cusps with severe aortic regurgitation. TEE is more sensitive than transthoracic echocardiography for the diagnosis of AAML and 3DTEE provides further morphological information as well about the relationship with adjacent structures. This information has important implications for medical and surgical purposes.
