Aortic regurgitation (AR), also known as aortic insufficiency (AI), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal.
Heyde's syndrome; A stenotic aortic valve: Specialty: Cardiology, general surgery, Hematology: Symptoms: Aortic valve stenosis symptoms: Chest pain (angina) or tightness Shortness of breath, especially during exertion or when lying down Fatigue or weakness Irregular heartbeat or heart palpitations Dizziness or fainting episodes Gastrointestinal bleeding symptoms: Occult (hidden) or overt ...
Aortic valve replacement is also recommended in patients that are asymptomatic but have chronic severe aortic regurgitation and left ventricular ejection fraction of less than 50%. [8] Hypertension is treated in patients with chronic aortic regurgitation, with the anti-hypersensives of choice being calcium channel blockers, ACE inhibitors, or ...
Regurgitation may also (in part) be due to congenital malformation of the aortic valve or concomitant stretching of a tricuspid aortic valve. Life expectancy may be limited by severe aortic regurgitation. The aneurysm of the ascending aorta may also become so large that it can develop rupture or dissection as life-threatening complications.
Just like aortic stenosis, treatment for aortic regurgitation is replacement of the valve after symptoms and left ventricular dysfunction develops. SUMMARY All right, as a quick recap…. Aortic stenosis happens if the aortic valve doesn’t open all the way, and aortic valve regurgitation happens if the valve doesn’t close all the way.
Men are more likely than women to develop idiopathic annuloaortic ectasia, which usually manifests in the fourth or sixth decades of life. Additional factors that contribute to this condition include osteogenesis imperfecta , inflammatory aortic diseases, intrinsic valve disease, Loeys-Dietz syndrome , Marfan syndrome , and operated congenital ...
Regurgitation in or near the heart is often caused by valvular insufficiency (insufficient function, with incomplete closure, of the heart valves); for example, aortic valve insufficiency causes regurgitation through that valve, called aortic regurgitation, and the terms aortic insufficiency and aortic regurgitation are so closely linked as ...
Aortic regurgitation, on the other hand, has many causes: degeneration of the cusps, endocarditis, bicuspid aortic valve, aortic root dilatation, trauma, connective tissue disorders such as Marfan syndrome or Ehlers-Danlos lead to imperfect closure of the valve during diastole, hence the blood is returning from the aorta towards the left ...
