A two-dimensional real-time echocardiographic study of a 51-year-old man with arterial emboli revealed an anterior wall aneurysm of the left ventricle containing mobile pedunculated masses. On the basis of this study alone, left ventricular aneurysmectomy and removal of a pedunculated thrombus were successfully performed.

Fatal atrial dislodgement of a lenticular disc occurred seven years after surgery in a 54-year-old patient, who had had a mitral valve replacement with a Cross-Jones prosthesis, for ruptured chordae tendinae. A marked distortion of the titanium ring reinforced silicone rubber lens disc due to material wear was the cause of this complication. From the literature available to us, atrial dislodgement of a prosthetic mitral occluder has not been previously recorded. We therefore intend to recommend elective replacement of the Cross-Jones prosthesis in all patients who have had their artificial valve functioning for more than five years.

Four infants with type C double aortic arch (double aortic arch with aberrant left subclavian artery) are discussed. The diagnosis was based on symptoms and signs of tracheoesophageal compression with a bilateral impression in the frontal plane of the esophagogram, as well as on early visualization of the aberrant left subclavian artery during counter-current right brachial angiography. Division of the atretic segment of the left arch and of the ligamentum arteriosum relieved the symptoms.
