[Asymptomatic aortic dissection in a patient with aortic valve prosthesis]. / Disección aórtica asintomática en paciente con prótesis valvular aórtica.

ABSTRACT

The occurrence of iatrogenic aortic dissection after aortic valve replacement is uncommon, usually late, and exceptionally asymptomatic. We present here a case of dissecting aneurysm suspected by excessive mediastinal dilatation observed in the routine annual roentgenogram exam of a patient who has had an aortic valve prosthesis for thirteen years. The confirmation with other diagnostic methods and its successful surgical treatment are also described.
