The ascending aorta may be the site of origin of systemic embolization in some cases that do not have an identifiable source. We report a case in which a free-floating thrombus in the noncoronary sinus of Valsalva was detected by transesophageal echocardiography as a source of left axillary artery embolism. After removal of this pedunculated thrombus of unknown cause, which was attached on a macroscopically and histologically normal aortic wall, the patient made an uneventful recovery.

Functional results of aortic valve repair with cusp extension using fresh pericardium have been satisfactory at medium term, particularly in children with a small aortic anulus at the time of initial repair, because the expansion potential of fresh autologous pericardium is equivalent to that of the growing sinotubular junction and aortic anulus diameters.

A rare case of congenital mitral insufficiency characterized by the hypoplasia of the posterior leaflet is reported. At operation, the mitral valve was successfully repaired by a ring annuloplasty, which created a satisfactory surface of coaptation between the anterior leaflet and the bulky posterior muscular structure. The presence of this posterior muscular structure represents a developmental arrest at the stage of conversion from muscular chordae and leaflets to thin connective structures.
