Arterial dissections happen when the inside wall of your artery tears. Blood gets in the tear and separates the layers of the artery wall. This dissection creates a weak spot that can lead to a life-threatening leak.
Can you survive SCAD?
Doctors used to view SCAD as frequently fatal but now think the mortality rate is low, ranging between 1% and 5%. But SCAD happens again more than previously believed, returning in more than 20% of people followed for a decade. Early and proper diagnosis is crucial to save lives and prevent sudden cardiac death.
