Kissing ulcer of the aortic wall in a patient with aortic valve endocarditis.

In patients with aortic valve endocarditis, lesion of the mitral valve leaflets caused by jet strike or vegetation touch (kissing) is a well-described complication. We present a case of infectious aortic ulcer caused by aortic valve vegetation kissing. A 72-year-old woman who underwent operation for Streptococcus viridans aortic valve endocarditis presented with a "kissing ulcer" in the aortic wall disclosed by intraoperative transesophageal echocardiography. The aortic valve was replaced by a bileaflet prosthesis, and the ulcer was closed with a small patch of autologous pericardium after thorough inspection. Transesophageal echocardiography performed before discharge showed a good surgical result without signs of infection recurrence. To the best of our knowledge, this is the first report of aortic wall involvement by the mechanism described.
