A case of spontaneous incomplete non-traumatic rupture of the ascending aorta with acute aortic insufficiency (successful emergency surgical repair).

Spontaneous incomplete non traumatic rupture of the ascending aorta is rare but life-threatening; it may well remain unnoticed until emergency surgery becomes necessary. Its possibility should be considered in all patients presenting signs of tamponade, chest pain or aortic regurgitation, and it must be diagnosed by appropriate procedures.
