Native mitral valve regurgitation. Proactive management can improve outlook

Area of Science:

• Cardiology
• Valvular Heart Disease

Background:

• Mitral regurgitation is a prevalent valvular abnormality associated with significant patient morbidity.
• Primary care physicians play a crucial role in suspecting and identifying mitral regurgitation, particularly in patients with heart failure symptoms.

Purpose of the Study:

• To emphasize the importance of early detection and prompt referral of patients with mitral regurgitation to cardiologists.
• To outline diagnostic and management strategies for mitral regurgitation.

Main Methods:

• Echocardiography is highlighted as a critical diagnostic tool for assessing regurgitation severity, valve integrity, and left ventricular function.
• Clinical presentation, including heart failure symptoms and ventricular dysfunction, guides the need for specialist evaluation.

Main Results:

• Echocardiography effectively determines regurgitation severity, mitral valve apparatus integrity, left ventricular enlargement, and ejection fraction.
• While no definitive medical treatment exists, ACE inhibitors are considered appropriate.
• Severe acute mitral regurgitation due to papillary muscle rupture requires prompt evaluation for ischemia.

Conclusions:

• Prompt identification and referral are paramount for patients with mitral regurgitation, especially those with symptoms or signs of ventricular dysfunction.
• Mitral valve repair is preferred for severe mitral regurgitation with left ventricular dysfunction; replacement with posterior chordal preservation is an alternative if repair is not feasible.
