The disease is commonly asymptomatic and is normally discovered when performing tests for other conditions such as coronary artery disease, stable angina and other acute coronary syndromes. [2] [3] Coronary artery ectasia occurs 4 times more frequently in males than in females and in people who have risk factors for heart disease such as smokers.
The smaller the aneurysm the better the prognosis. There is less risk for ischemic myocardial damage and mortality with smaller aneurysms. Aneurysms with an internal diameter > 8 mm have poorer outcomes, since these aneurysms can be occluded and be associated with complications such as arrhythmias, myocardial infarction, or sudden death. [2]
Thoracic aneurysms are less common than an abdominal aortic aneurysm. [2] However, a syphilitic aneurysm is more likely to be a thoracic aortic aneurysm than an abdominal aortic aneurysm. This condition is commonly treated via a specialized multidisciplinary approach with both vascular surgeons and cardiac surgeons .
An aortic aneurysm is an enlargement (dilatation) of the aorta to greater than 1.5 times normal size. [1] Typically, there are no symptoms except when the aneurysm dissects or ruptures, which causes sudden, severe pain in the abdomen and lower back. [2] [3] The etiology remains an area of active research.
Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease, and heart attacks. [4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [5]
In approximately 33% of individuals, the left coronary artery gives rise to the posterior descending artery [4] which perfuses the posterior and inferior walls of the left ventricle. Sometimes a third branch is formed at the fork between left anterior descending and left circumflex arteries, known as a ramus or intermediate artery .
[1] [5] From 1996 to spring 2007, the US National Commotio Cordis Registry had 188 cases recorded, with about half occurring during organized sports. [6] Almost all (96%) of the victims were male, the mean age of the victims during that period was 14.7 years, and fewer than one in five survived the incident. [6]
For many years, the gold standard treatment for patients with aortic valve disease and aortic root aneurysms was to replace both the aortic valve and the ascending aorta with a composite graft. This also applies to patients with different levels of AI and annuloaortic ectasia, where the aortic valve may be largely preserved without any ...
