What is Mitral Regurgitation?

Mitral regurgitation occurs when the mitral valve fails to close completely during left ventricular contraction, allowing blood to flow back into the left atrium instead of forward into the ventricle. This places additional volume and pressure load on the left heart.

The most common causes of primary mitral regurgitation are mitral valve prolapse, rheumatic heart disease, and infective endocarditis. Secondary (functional) mitral regurgitation arises secondary to heart failure or ischemic heart disease.

Chronic cases may remain asymptomatic for many years. Planning intervention before left ventricular dysfunction or pulmonary hypertension develops is important to preserve cardiac function.

Symptoms

Shortness of breath on exertion and at rest
Fatigue and reduced exercise capacity
Palpitations and atrial fibrillation
Swelling of the legs and ankles
Cough (from fluid in the lungs)
Heart murmur (detected on examination)

Risk Factors

Mitral valve prolapse
History of rheumatic fever
Infective endocarditis
Dilated cardiomyopathy
Prior heart attack

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • For echocardiographic assessment when a murmur is detected
  • If exertional dyspnea or fatigue worsens
  • If atrial fibrillation or palpitations develop
  • For periodic echocardiography every six months with cardiology follow-up

Treatment Methods

01
Follow-up echocardiography and medical therapy in mild-to-moderate cases
02
Diuretics and RAAS blockers for symptom control
03
Mitral valve repair (preferred when valve anatomy is suitable)
04
Mitral valve replacement (when repair is not possible)
05
Transcatheter mitral valve repair (in high-risk patients)

Hypertension (High Blood Pressure)

Kardiyoloji

Hypertension is a condition in which blood pressure readings remain above 140/90 mmHg; early treatment helps prevent serious complications.

Coronary Artery Disease

Kardiyoloji

Narrowing of the coronary arteries due to atherosclerosis can cause chest pain (angina) and heart attack.

Heart Failure

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial Fibrillation

Kardiyoloji

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
