What would be the sound heard for a stenotic mitral valve?
The diastolic murmur of mitral stenosis is of low pitch, rumbling in character, and best heard at the apex with the patient in the left lateral position. It commences after the opening snap of the mitral valve, and the duration of the murmur correlates with the severity of the stenosis.
What sound does a stenosis make?
Aortic stenosis: Murmur: Harsh late-peaking crescendo-decrescendo systolic murmur.
What does a stenotic aortic valve sound like?
The typical murmur of aortic stenosis is a high-pitched, “diamond shaped” crescendo-decrescendo, midsystolic ejection murmur heard best at the right upper sternal border radiating to the neck and carotid arteries (see figure below). In mild aortic stenosis, the murmur peaks in early systole.
What are S1 S2 S3 and S4 heart sounds?
These two phases constitute the heartbeat. In a healthy adult, the heart makes two sounds, commonly described as ‘lub’ and ‘dub. ‘ The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.
Where do you listen for mitral valve?
Standard sites for auscultation – Mitral area – left fifth intercostal space, mid-clavicular line. This is where the mitral valve sounds are best auscultated; – Tricuspid area – left fourth intercostal space, just lateral to the sternum.
What does a murmur sound like?
Heart murmurs are sounds — such as whooshing or swishing — made by turbulent blood in or near your heart. Your doctor can hear these sounds with a stethoscope. A normal heartbeat makes two sounds like “lubb-dupp” (sometimes described as “lub-DUP”) when your heart valves are closing.
Is S1 systole or diastole?
S1 and the 2nd heart sound (S2, a diastolic heart sound) are normal components of the cardiac cycle, the familiar “lub-dub” sounds. S1 occurs just after the beginning of systole and is predominantly due to mitral closure but may also include tricuspid closure components.
What kind of murmur is heard with aortic stenosis?
Stenosis of the aortic or pulmonic valves will result in a systolic murmur, as blood is ejected through the narrowed orifice. Conversely, regurgitation of the same valves will result in a diastolic murmur, as blood flows backward through the diseased valve when ventricular pressures drop during relaxation.
Why 2nd heart sound is soft in aortic stenosis?
The most common cause of paradoxical splitting of the second sound is left bundle branch block. Obstruction to left ventricular outflow of sufficient severity to delay aortic valve closure may also cause paradoxical splitting. In the context of aortic stenosis, such an auscultatory finding implies severe obstruction.
Is S3 a murmur?
The third heart sound or S3 is a rare extra heart sound that occurs soon after the normal two “lub-dub” heart sounds (S1 and S2). S3 is associated with heart failure….

What is S3 and S4 sound?
The main normal heart sounds are the S1 and the S2 heart sound. The S3 can be normal, at times, but may be pathologic. A S4 heart sound is almost always pathologic. Heart sounds can be described by their intensity, pitch, location, quality and timing in the cardiac cycle.
What are the signs and symptoms of aortic valve stenosis?
Signs and symptoms of aortic valve stenosis may include: Aortic valve stenosis may lead to heart failure. Heart failure signs and symptoms include fatigue, shortness of breath, and swollen ankles and feet. If you have a heart murmur, your doctor may recommend that you visit a doctor trained in diseases of the heart (cardiologist).
What is aortic valve stenosis and how is it treated?
Aortic valve stenosis — or aortic stenosis — occurs when the heart’s aortic valve narrows. The valve doesn’t open fully, which reduces or blocks blood flow from your heart into the main artery to your body (aorta) and to the rest of your body. Your treatment depends on the severity of your condition.
Can a stethoscope detect heart valve disease?
One of the primary exams used to detect heart valve disease involves the stethoscope. While this diagnostic device, invented by Rene Laennec in 1816, is not as technologically advanced as 3D-MTEE imaging, stethoscopes can help cardiologists and surgeons quickly identify variable forms of heart valve disease.
What is the most common cause of aortic stenosis?
Causes of Valve Stenosis All types of heart valve disease are more common with age, although some may be caused by congenital heart defects. For example, a type of malformed aortic valve is a bicuspid aortic valve.
