Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. [1] It is almost always caused by rheumatic valvular heart disease . Normally, the mitral valve is about 5 cm 2 during diastole.
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
Mitral valve replacement is a procedure whereby the diseased mitral valve of a patient's heart is replaced by either a mechanical or tissue (bioprosthetic) valve. The mitral valve may need to be replaced because: [1] The valve is leaky (mitral valve regurgitation) The valve is narrowed and doesn't open properly (mitral valve stenosis)
If the mitral valve doesn’t shut all the way, blood can leak back into the left atrium, called mitral valve regurgitation. During diastole, the mitral valve opens and lets blood fill into the ventricle. If the mitral valve doesn’t open enough, it gets harder to fill the left ventricle, called mitral valve stenosis.
In general, the shorter the duration (S2 to Opening Snap), the more severe the mitral stenosis. However, this rule can be misleading in situations where the stenosis is so severe that the flow becomes reduced, or during high-output situations such as pregnancy where a less severe stenosis may still produce a strong murmur.
Acute coronary syndrome (ACS) is a syndrome due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. [1] The most common symptom is centrally located pressure-like chest pain , often radiating to the left shoulder [ 2 ] or angle of the jaw, and associated with nausea and ...
The left side of the heart is more muscular than the right side of the heart. It pumps oxygenated blood from the lungs into the aorta to perfuse the rest of the body. [4] When the heart has to pump against increased resistance, or afterload, as in the case of a ventricular obstruction, it compensates by growing in size. This adaptation is ...
Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart.
