Aortic valve disease is a type of heart valve disease. In this condition, the valve between the lower left heart chamber and the body's main artery doesn't work properly. The aortic valve helps keep blood flowing in the correct direction through the heart. A damaged or diseased aortic valve can affect blood flow to the rest of the heart and body.

2024年7月10日 · The aortic valve is between the lower left heart chamber and the body's main artery, called the aorta. Aortic valve calcification is a condition in which calcium builds up on the aortic valve. Buildups of calcium can cause the valve opening to become narrow.

2024年6月11日 · Aortic valve stenosis. The aortic valve flaps, called cusps, become thick and stiff, or they connect together. The valve becomes narrowed or doesn't open fully. This reduces or blocks blood flow. Aortic valve stenosis may be caused by a heart condition present at birth or by some infections that affect the heart valve.

2024年10月18日 · In aortic valve stenosis, the valve between the lower left heart chamber, called the left ventricle, and the body's main artery, called the aorta, is narrowed and doesn't open completely. This narrowing is called stenosis. When the aortic valve opening is narrowed, the heart must work harder to pump enough blood to the body.

During aortic valve repair, the surgeon may do one or all of the following: Separate valve flaps that have fused. Add support to the base of the valve. Reshape or remove excess valve tissue so that the cusps can close tightly. Patch holes or tears in a …

2023年10月4日 · Aortic valve regurgitation — also called aortic regurgitation — is a type of heart valve disease. The valve between the lower left heart chamber and the body's main artery doesn't close tightly. As a result, some of the blood pumped out of the heart's main pumping chamber, called the left ventricle, leaks backward.

2024年10月18日 · Aortic valve replacement. Aortic valve replacement is often needed to treat aortic valve stenosis. In aortic valve replacement, the surgeon takes out the damaged valve and replaces it with a mechanical valve or a valve made from cow, pig or human heart tissue. A tissue valve is called a biological tissue valve.

2023年10月4日 · Aortic valve repair. To repair an aortic valve, surgeons may separate valve flaps, also called cusps, that have connected. They might reshape or remove excess valve tissue so that the cusps can close tightly. Or they might patch holes in a valve. A catheter procedure may be done to place a plug or device in a leaking replacement aortic valve.

Mitral valve regurgitation. The mitral valve flaps, also called leaflets, may not close tightly. This causes blood to leak backward. Mitral valve stenosis. The flaps of the mitral valve become thick or stiff, and they can fuse together. This narrows the valve opening, which reduces blood flow from the left atrium to the left ventricle.

2023年11月22日 · Transcatheter aortic valve replacement (TAVR) is a type of heart valve surgery. It's done to replace a narrowed aortic valve, a condition called aortic valve stenosis. A doctor inserts a flexible tube called a catheter into a blood vessel and guides it into the heart. A replacement valve made of cow or pig tissue goes through the tube to the ...
