Why does Gallavardin phenomenon occur?
This is the result of radiation of the murmur of aortic valve stenosis to the apex rather than coexistent mitral regurgitation. This finding is sometimes referred to as “Gallavardin dissociation.”
Does aortic sclerosis radiate to carotids?
Aortic stenosis radiates to the right carotid artery and aortic sclerosis does not.
What causes crescendo decrescendo murmur?
Mid-systolic murmurs typically have a crescendo-decrescendo character, that is, they start softly and become loudest near mid-systole, followed by a decrease in sound intensity as shown in the figure to the right. This type of murmur is caused by either aortic or pulmonic valve stenosis.
What is the most common cause of aortic stenosis in adults as?
In most elderly adults, aortic stenosis is caused by a build-up of calcium (a mineral found in your blood) on the valve leaflets. Over time, this causes the leaflets to become stiff, reducing their ability to fully open and close.
How can you tell the difference between aortic stenosis and aortic sclerosis?
Aortic sclerosis is thickening of the valve without any significant effect on the function of the valve itself. Aortic stenosis is thickening and tightening of the valve that leads to the heart having to work harder and the possibility of not enough blood being delivered to the body.
Why does handgrip increase afterload?
The handgrip maneuver increases afterload by squeezing the arterioles and increasing total peripheral resistance.
What is a decrescendo murmur?
Decrescendo murmurs progressively decrease in intensity. With crescendo—decrescendo murmurs (diamond or kite-shaped murmurs), a progressive increase in intensity is followed by a progressive decrease in intensity. Plateau murmurs maintain a relatively constant intensity.
What symptoms indicate worsening of aortic stenosis?
Call your doctor about new or worsening symptoms, including:
- Chest pain or tightness.
- Rapid fluttering heartbeat.
- Shortness of breath.
- Dizziness or faintness.
- Increased exhaustion after activity.
- Swollen ankles and feet.
- Difficulty sleeping.
