Aortic stenosis murmur, what are the characteristics

Rheumatic heart disease is quite common nowadays, and aortic valve stenosis is the most common one among them. This disease generally has a symptom of murmur, but many people do not know much about it, so they are not clear what the murmur is like. Here we will introduce you to the related issues about the murmur of aortic valve stenosis.

Patients with aortic valve stenosis may experience a lot of pain. In fact, there is still a lot of disease knowledge that we can consider in understanding the disease management and treatment of aortic valve stenosis. In today's society, when we deal with a disease well, the first thing we need to consider is the patient's condition, so that we can achieve our goal.

Systolic murmur in the aortic valve area: A loud (≥3-4/VI), rough, high-pitched, long-lasting, blowing-like jet-like systolic murmur is heard in the aortic valve area. This murmur is caused by the systolic blood flow through the stenotic valve, causing vortexes in the ascending aorta. The murmur is diamond-shaped, appears after S1, reaches its peak in the middle and late stages of contraction, and disappears after S2. Conducted to the carotid and subclavian arteries on both sides. As the degree of aortic valve stenosis increases, the murmur becomes louder, lasts longer, and the diamond-shaped peak moves backward. However, when severe aortic stenosis is accompanied by heart failure or tachycardia, the murmur becomes short and soft.

Early aortic systolic ejection sound: When the aortic valve is mildly or moderately stenotic, an early systolic ejection sound can be heard in the aortic valve area or the second auscultation area of ​​the aortic valve. Immediately after S1, there is a short and loud extra sound. It is caused by the sudden opening of the aortic valve, which causes high-speed blood flow to impact the stenotic aortic valve and cause vibration. It is more common in congenital aortic valve stenosis in children and adolescents. If it is rheumatic aortic valve stenosis, the valve mobility is affected due to adhesion and thickening of the valve, so this ejection sound is rarely heard.

According to the above introduction, we can understand that aortic valve stenosis mainly causes systolic murmur and systolic murmur. Heart murmurs can reflect the severity of the patient's condition to a certain extent. If we find any signs of heart murmur, we should be alert.
