Mitral valve prolapse (MVP) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. [4] It is the primary form of myxomatous degeneration of the valve.
It is one of the two most common valvular heart diseases in the elderly, [27] and the commonest type of valvular heart disease in low and middle income countries. [3] In a study of 595 male elite football players aged 18–38 and 47 sedentary non-athletes, mitral regurgitation was found in 20% football players and 15% in control group. Football ...
If pulmonary hypertension secondary to mitral stenosis is severe, the P 2 (pulmonic) component of the second heart sound (S 2) will become loud. [citation needed] An opening snap that is a high-pitch additional sound may be heard after the A 2 (aortic) component of the second heart sound (S 2), which correlates to the forceful opening of the ...
These are short, high-pitched sounds. [citation needed] The mitral valve in cases of mitral stenosis may open with an opening snap [1] [2] on the beginning of diastole. Patients with mitral valve prolapse may have a mid-systolic click along with a murmur, referred to as apical late systolic murmur. [3]
Valve failure or dysfunction can result in diminished heart functionality, though the particular consequences are dependent on the type and severity of valvular disease. Treatment of damaged valves may involve medication alone, but often involves surgical valve repair or valve replacement. [citation needed]
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia.
A valve prolapse can result in mitral insufficiency, which is the regurgitation or backflow of blood from the left ventricle to the left atrium due to the incomplete closure of the valve causing a systolic murmur heard at the apex of the heart. This increase in pressure in the left atrium and pulmonary circuit can lead to symptoms like fatigue ...
Propafenone generally needs to be started in a hospital setting to assure ECG monitoring of the patient. There are many different dosages of propafenone, depending on clinical presentation of the arrhythmia. The treatment is generally begun with a relatively high dose (450–900 mg/d), decreasing to near 300 mg/d.
