Spontaneous coronary artery dissection (SCAD) is an uncommon but potentially lethal condition in which one of the coronary arteries that supply the heart, spontaneously develops a blood collection, or hematoma, within the artery wall due to a tear in the wall.
Arterial dissections become life-threatening when growth of the false lumen prevents perfusion of the true lumen and the related end organs. For example, in an aortic dissection, if the left subclavian artery orifice were distal to the origin of the dissection, then the left subclavian would be said to be perfused by the false lumen, while the left common carotid (and its end organ, the left ...
Evidence remains inconclusive about whether these risks outweigh the benefit of a coronary arterial stent. [3] [4] Inflammation may play a causal role in coronary artery disease and subsequent myocardial infarction due to coronary thrombosis. Increased levels of inflammation may lead to higher risk of clotting as well as an increased risk of ...
Purulent Pericarditis; Echocardiogram showing pericardial effusion with signs of cardiac tamponade: Specialty: Cardiology: Symptoms: substernal chest pain (exacerbated supine and with breathing deeply), dyspnea, fever, rigors/chills, and cardiorespiratory signs (i.e., tachycardia, friction rub, pulsus paradoxus, pericardial effusion, cardiac tamponade, pleural effusion)
Ventricular aneurysms are one of the many complications that may occur after a heart attack.The word aneurysm refers to a bulge or 'pocketing' of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum, or within the aorta.
The incidence of spontaneous carotid artery dissection is low, and incidence rates for internal carotid artery dissection have been reported to be around 2.6 to 2.9 incidents per 100,000. [14] Though the incidence is low, it is the cause of the vast majority of strokes in young people. [15]
It refers to a dissection that occurs solely in the superior mesenteric artery (SMA), typically spontaneously, and does not involve the aorta. [1] Although aortic dissection can frequently extend into its peripheral territories, it is rare for these branches to have dissection without main aortic trunk involvement. The SMA is the most common ...
