Mitral Valve Prolapse-The Role of Cardiac Imaging Modalities.

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Mitral valve prolapse (MVP) is the leading cause of nonischemic mitral regurgitation and a common reason for cardiac surgery in Western countries.
• MVP is increasingly recognized as a complex condition affecting the entire mitral valve apparatus, cardiac function, and heart structure.

Purpose of the Study:

• To review recent advancements in cardiac imaging for mitral valve prolapse (MVP).
• To highlight how new imaging insights aid in MVP diagnosis, risk stratification, treatment, and patient follow-up.

Main Methods:

• Echocardiography (transthoracic and transesophageal) is the primary diagnostic tool for MVP, assessing leaflets, annulus, chords, and papillary muscles.
• Cardiac MRI and CT offer high-resolution anatomical detail, complementing echocardiography.
• Emerging techniques like 3D echocardiography and tissue Doppler imaging provide novel insights into MVP.

Main Results:

• Cardiac imaging is crucial for diagnosing MVP by visualizing leaflet displacement into the left atrium.
• Imaging modalities help assess the anatomical and functional consequences of MVP.
• New imaging techniques are enhancing the understanding of MVP mechanisms and patient outcomes.

Conclusions:

• Cardiac imaging plays a pivotal role in the comprehensive management of mitral valve prolapse.
• Advanced imaging techniques are essential for accurate diagnosis, risk assessment, and guiding treatment strategies for MVP.
• Ongoing developments in cardiac imaging promise further improvements in understanding and managing MVP.
