Mitral Facies
Mitral facies is a distinctive facial appearance associated with mitral stenosis. Someone with mitral stenosis may present with rosy cheeks, whilst the rest of the face has a bluish tinge due to cyanosis Cyanosis is the change of body tissue color to a bluish-purple hue as a result of having decreased amounts of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. Body tissues that show cyanosis are usually in locations .... This is especially so in severe mitral stenosis. Because low cardiac output in mitral stenosis produces vasoconstriction, peripheral cyanosis is often seen in the lips, the tip of nose, and the cheeks. Occasionally, along with these, malar flush is seen, because of vasodilation (vascular stasis) in the malar area.

Facies (medical)
In medical contexts, a facies is a distinctive facial expression or appearance associated with a specific medical condition. The term comes from Latin for "face". As a fifth declension noun, ''facies'' can be both singular and plural. Types Examples include: * Hippocratic facies – eyes are sunken, temples collapsed, nose is pinched with crusts on the lips, and the forehead is clammy * Moon face (also known as "Cushingoid facies") – Cushing's syndrome * Elfin facies – Williams syndrome * Potter facies – oligohydramnios * Mask like facies – parkinsonism * Leonine facies – lepromatous leprosy or craniometaphyseal dysplasia * Mitral facies – mitral stenosis * Amiodarone facies (deep blue discoloration around malar area and nose) * Acromegalic facies – acromegaly * Flat facies – Down syndrome * Marfanoid facies – Marfan's syndrome * Snarling facies – myasthenia gravis * Myotonic facies – myotonic dystrophy * Torpid facies – myxoedema * Mouse facie ...

Mitral Stenosis
Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. It is almost always caused by rheumatic valvular heart disease. Normally, the mitral valve is about 5 cm2 during diastole. Any decrease in area below 2 cm2 causes mitral stenosis. Early diagnosis of mitral stenosis in pregnancy is very important as the heart cannot tolerate increased cardiac output demand as in the case of exercise and pregnancy. Atrial fibrillation is a common complication of resulting left atrial enlargement, which can lead to systemic thromboembolic complications like stroke. Signs and symptoms Signs and symptoms of mitral stenosis include the following: * Heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea (PND) * Palpitations * Chest pain * Hemoptysis * Thromboembolism in later stages when the left atrial volume is increased (i.e., dilation). The latter leads to increase risk of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanosis
Cyanosis is the change of body tissue color to a bluish-purple hue as a result of having decreased amounts of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. Body tissues that show cyanosis are usually in locations where the skin is thinner, including the mucous membranes, lips, nail beds, and ear lobes. Some medications containing amiodarone or silver, Mongolian spots, large birth marks, and the consumption of food products with blue or purple dyes can also result in the bluish skin tissue discoloration and may be mistaken for cyanosis. Cyanosis is further classified into central cyanosis vs. peripheral cyanosis. Pathophysiology The mechanism behind cyanosis is different depending on whether it is central or peripheral. Central cyanosis Central cyanosis is caused by a decrease in arterial oxygen saturation (SaO2) and begins to show once the concentration of deoxyhemoglobin in the blood reaches a concentration of ≥ 5.0 g/dL (≥ 3.1 mmol/L ...

Medical Signs
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indicatio ...
