Arrhythmic Mitral Valve Prolapse: Pathophysiology, Diagnostics, and Management Strategies

Area of Science:

• Cardiology
• Cardiac Electrophysiology

Background:

• Mitral valve prolapse (MVP) is a common valvular heart condition.
• MVP is associated with an elevated risk of ventricular arrhythmias and sudden cardiac death.
• Arrhythmias can be the initial clinical manifestation of MVP.

Purpose of the Study:

• To review the pathological mechanisms underlying ventricular arrhythmias in MVP.
• To summarize current diagnostic strategies for MVP.
• To discuss contemporary management approaches for MVP.

Main Methods:

• Literature review of relevant studies on MVP, ventricular arrhythmias, diagnosis, and management.
• Synthesis of evidence from preclinical and clinical research.
• Analysis of current clinical guidelines and expert consensus.

Main Results:

• Pathological mechanisms include valvular-related myocardial changes and neurohormonal activation.
• Diagnostic tools include echocardiography and electrophysiological studies.
• Management strategies range from observation to antiarrhythmic drugs and interventions.

Conclusions:

• Understanding MVP's arrhythmogenic potential is crucial for risk stratification.
• Early diagnosis and appropriate management can mitigate the risk of sudden cardiac death.
• Further research is needed to refine risk prediction and treatment protocols.
