Arterial dissections occur when there is a tear or damage to the inner wall or lining of an artery. Dissections occur most often in the aorta, the carotid artery and the vertebral artery. An aortic dissection occurs when the inner layer or lining of the aorta tears and allows blood to enter into the wall of the aorta.
Hereof, what causes a tear in your heart?
An aortic dissection occurs in a weakened area of the aortic wall. Chronic high blood pressure may stress the aortic tissue, making it more susceptible to tearing. Rarely, aortic dissections are caused by traumatic injury to the chest area, such as during motor vehicle accidents.
What causes a tear in the carotid artery?
Arterial dissection of the carotid arteries occurs when a small tear forms in the innermost lining of the arterial wall (known as the tunica intima). Blood is then able to enter the space between the inner and outer layers of the vessel, causing narrowing (stenosis) or complete occlusion.
What does a tear in the heart mean?
Myocardial rupture is a laceration of the ventricles or atria of the heart, of the interatrial or interventricular septum, or of the papillary muscles. It is most commonly seen as a serious sequela of an acute myocardial infarction (heart attack).
