Mitral Stenosis

What is Mitral Stenosis:

Mitral stenosis is a heart condition characterized by the narrowing of the mitral valve, which controls blood flow between the upper and lower chambers of the heart.

This narrowing restricts the blood flow from the left atrium to the left ventricle, leading to various symptoms and complications.

Side effects of Mitral Stenosis:

Patients with mitral stenosis may experience a range of symptoms, including shortness of breath, especially during physical activity or when lying down flat (orthopnea), fatigue, palpitations, chest pain, coughing, and even fainting episodes in severe cases.

Over time, untreated mitral stenosis can lead to serious complications such as atrial fibrillation, heart failure, pulmonary hypertension, and an increased risk of blood clots and stroke.

How is Mitral Stenosis diagnosed?:

Diagnosing mitral stenosis typically involves a combination of medical history review, physical examination, and various diagnostic tests. Doctors may listen to the heart using a stethoscope to detect abnormal heart sounds (such as a heart murmur) and may order tests such as echocardiography (including transesophageal echocardiography), electrocardiogram (ECG), chest X-ray, cardiac catheterization, and cardiac magnetic resonance imaging (MRI) to confirm the diagnosis and assess the severity of the condition.

Potential treatments of Mitral Stenosis:

The treatment approach for mitral stenosis depends on the severity of the condition and the presence of symptoms. In mild cases, close monitoring by a cardiologist may be sufficient.

However, for patients with moderate to severe mitral stenosis or those experiencing symptoms, various treatment options may be considered:

• Medications: Medications such as diuretics (to reduce fluid buildup), beta-blockers (to control heart rate), and anticoagulants (to prevent blood clots) may be prescribed to manage symptoms and reduce the risk of complications.

• Percutaneous Mitral Balloon Valvuloplasty (PMBV): This minimally invasive procedure involves inserting a deflated balloon through a catheter into the narrowed mitral valve and then inflating it to widen the valve opening, improving blood flow. PMBV can be an effective treatment for suitable candidates, often providing symptomatic relief and improving heart function.

• Mitral Valve Repair or Replacement Surgery: In cases where other treatments are ineffective or unsuitable, surgical intervention may be necessary. Mitral valve repair aims to restore the function of the native valve by removing excess tissue or repairing damaged components, while mitral valve replacement involves replacing the diseased valve with a mechanical or biological prosthetic valve. Both procedures can significantly improve symptoms and quality of life for patients with severe mitral stenosis.

• Watchful Waiting: In some cases, particularly in elderly patients or those with multiple comorbidities, a conservative approach involving close monitoring of symptoms and periodic assessments may be recommended instead of immediate intervention.
