Overview
Patients with mitral stenosis who develop atrial fibrillation require anticoagulation and rate control. Medical therapy for mitral stenosis includes anticoagulation and rate control (to increase diastolic filling time) in those patients with atrial fibrillation. Medical therapy can relieve symptoms, but the patient may need surgery to relieve the blood flow obstruction by mitral stenosis. Surgical treatment in the symptomatic patient reduces the mortality rate of mitral stenosis compared to medical treatment.[1][2][3] The interventional and surgical treatments for mitral stenosis include: percutaneous mitral balloon valvotomy (PMBV), closed commissurotomy, open commissurotomy (valve repair), mitral valve replacement.
Medical Therapy
Treatment of Acute Decompensation
Digoxin
- Digitalis may be used among patients with AS and symptomatic right ventricular or left ventricular dysfunction.
- Digitalis may be used to strengthen the heartbeat and to slow the ventricular response in patients with atrial arrhythmias. Slowing the heart rate prolongs the diastolic filling time and allows better filling of the left ventricle.
Diuretics
- Diuretics may be used to remove excess fluid in the lungs in patients with pulmonary edema.
Low Sodium Diet
A low-sodium diet may be helpful.
Activity Restriction
Once a a patient develops symptoms, activity may be restricted.
Systemic Embolization Prevention
Anticoagulation therapy is indicated for thromboembolic events prevention among AS patients in any of the following conditions:(Class I, Level of Evidence B)
- Paroxysmal, persistent, or permanent atrial fibrillation
- Prior embolization event
- Left atrial thrombus
Rate Control
Rate control with either beta blockers or calcium channel blocker is indicated in MS in the following conditions:
- Atrial fibrillation associated with fast ventricular response (Class IIa, Level of Evidence C)
- Normal sinus rhythm plus symptoms associated with exercise (Class IIb, Level of Evidence B)
Secondary Prevention of Rheumatic Fever
Prevention of Endocarditis
2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart Disease: Executive Summary[4]
| Class I |
"1. Anticoagulation (vitamin K antagonist or heparin) is indicated in patients with:
|
| Class IIa |
| "1. Heart rate control can be beneficial in patients with MS and AF and fast ventricular response. (Level of Evidence: C) " |
| Class IIb |
| "1. Heart rate control may be considered for patients with MS in normal sinus rhythm and symptoms associated with exercise. (Level of Evidence: B) " |
2008 and Incorporated 2006 ACC/AHA Guidelines for the Management of Patients with Valvular Heart Disease (DO NOT EDIT)[5]
Systemic Embolization Prevention (DO NOT EDIT)[5]
| Class I |
| "1. Anticoagulation is indicated in patients with mitral stenosis and atrial fibrillation (paroxysmal, persistent, or permanent). (Level of Evidence: B) " |
| "2. Anticoagulation is indicated in patients with mitral stenosis and a prior embolic event, even in sinus rhythm. (Level of Evidence: B) " |
| "3. Anticoagulation is indicated in patients with mitral stenosis with left atrial thrombus. (Level of Evidence: B) " |
| Class IIb |
| "1. Anticoagulation may be considered for asymptomatic patients with severe mitral stenosis and left atrial dimension greater than or equal to 55 mm by echocardiography.* (Level of Evidence: B) " |
| "2. Anticoagulation may be considered for patients with severe mitral stenosis, an enlarged left atrium, and spontaneous contrast on echocardiography. (Level of Evidence: C) " |
