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.
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.
The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis. Current methods for aortic valve replacement include open-heart surgery , minimally invasive cardiac surgery (MICS) , surgical aortic valve replacement (SAVR) and percutaneous or transcatheter aortic valve replacement ...
Aortic stenosis; In the center an aortic valve with severe stenosis due to rheumatic heart disease. The valve is … surrounded by the aorta. The pulmonary trunk is at the upper right. The right coronary artery, cut lengthwise, is at the lower left. The left main coronary artery, also cut lengthwise, is on the right. Specialty: Cardiac surgery ...
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 ...
Aortic valvuloplasty, also known as balloon aortic valvuloplasty (BAV), is a procedure used to improve blood flow through the aortic valve in conditions that cause aortic stenosis, or narrowing of the aortic valve. It can be performed in various patient populations including fetuses, newborns, children, adults, and pregnant women.
De Musset's sign is a type of rhythmic bobbing of the head in synchrony with the beating of the heart, seen in severe aortic regurgitation. [1]This sign occurs as a result of blood from the aorta regurgitating into the left ventricle due to a defect in the aortic valve.
[31] [32] It was the first aortic valve device to receive FDA approval, in November 2011 for use in inoperable patients and in October 2012 for use in patients at high surgical risk. [33] The device is effective in improving functioning in patients with severe aortic stenosis. It is now approved in more than 50 countries. [citation needed]
