Watchful waiting for severe mitral regurgitation

Area of Science:

• Cardiology
• Cardiac Surgery
• Clinical Medicine

Background:

• Severe organic mitral regurgitation (OMR) management involves watchful waiting for asymptomatic patients.
• Current guidelines define surgical indications based on symptoms, left ventricular (LV) function, and LV size.
• The optimal timing for surgical intervention in asymptomatic patients with preserved LV function remains debated.

Purpose of the Study:

• To review the established strategy of watchful waiting for severe OMR.
• To discuss the current indications for surgical intervention in OMR.
• To highlight the importance of individualized decision-making in managing OMR.

Main Methods:

• Review of European Society of Cardiology and American Heart Association/American College of Cardiology guidelines.
• Analysis of clinical and echocardiographic follow-up strategies.
• Consideration of patient-specific factors and surgical risks.

Main Results:

• Watchful waiting is effective when patients are monitored clinically and echocardiographically.
• Surgery in expert centers leads to excellent outcomes.
• Early recognition and referral are crucial to avoid delayed treatment.

Conclusions:

• Watchful waiting, combined with periodic monitoring and timely surgery, offers excellent outcomes for severe OMR.
• Individualized treatment decisions considering disease natural history, surgical risk, and repair likelihood are paramount.
• Further research may clarify the role of surgery in asymptomatic patients with preserved LV function.
