The natural history of mitral stenosis secondary to rheumatic fever (the most common cause) is an asymptomatic latent phase following the initial episode of rheumatic fever. This latent period lasts an average of 16.3 ± 5.2 years. Once symptoms of mitral stenosis begin to develop, progression to severe disability takes 9.2 ± 4.3 years.
The symptoms and signs of left atrial myxomata often mimic mitral stenosis. General symptoms may also be present, such as: [3] Cough; Pulmonary edema – as blood backs up into the pulmonary artery, after increased pressures in the left atrium and atrial dilation; Hemoptysis; Fever; Cachexia – Involuntary weight loss; General discomfort ...
Symptoms of mitral stenosis increase with exercise and pregnancy [16] On auscultation of a patient with mitral stenosis, typically the most prominent sign is a loud S 1. [16] Another finding is an opening snap followed by a low-pitched diastolic rumble with presystolic accentuation.
In general, unless the ASD and mitral stenosis causing Lutembacher's syndrome is severe, symptoms may not appear until the second and third decade of the patient's life. [ citation needed ] As many of the patients are asymptomatic and symptoms may not appear until later in life, the duration or frequency of the symptoms varies.
Mitral stenosis causes left atrial pressure to increase, which, if left untreated, can lead to ventricular dilation, hypertrophy, atrial fibrillation, and thrombus creation. Symptoms include shortness of breath ( dyspnea ) on exertion, when lying flat ( orthopnea ) or during the night ( paroxysmal nocturnal dyspnea ), and fatigue.
Mitral stenosis presents as a diastolic low-pitched decrescendo murmur. It is best heard at the cardiac apex in the left lateral decubitus position. Mitral stenosis may have an opening snap. Increasing severity will shorten the time between S2 (A2) and the opening snap. For example, in severe MS the opening snap will occur earlier after A2.
Mitral valve stenosis may cause malar flush due to CO 2 retention, which causes vasodilation of arterioles in the cheeks. [1] It can also be associated with other conditions, such as lupus, [2] polycythemia vera [3] and homocystinuria. [4]
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. This is especially so in severe mitral stenosis. Because low cardiac output in mitral stenosis produces vasoconstriction, peripheral cyanosis ...
