Mitral valve (MV) is composed of several structures working in synchrony to open during diastole and close in systole within the high-pressure systemic environment. Its morphological features ensure a normal leaflet closure that prevents regurgitation of blood back into the left atrium causing loss of ventricular pressure and forward flow. The complex interactions of the normal MV are reliant on each component playing a complete role for the efficient working of the valve. In this review we firstly discuss the overall MV structure in terms of a complex make up of the annulus, the leaflets, their tendinous cords, and the supporting papillary muscles, and then the anatomical changes of each MV components due to left ventricular geometry and function alterations, underlying functional mitral regurgitation

Abstract

Mitral valve (MV) is composed of several structures working in synchrony to open during diastole and close in systole within the high-pressure systemic environment. Its morphological features ensure a normal leaflet closure that prevents regurgitation of blood back into the left atrium causing loss of ventricular pressure and forward flow. The complex interactions of the normal MV are reliant on each component playing a complete role for the efficient working of the valve. In this review we firstly discuss the overall MV structure in terms of a complex make up of the annulus, the leaflets, their tendinous cords, and the supporting papillary muscles, and then the anatomical changes of each MV components due to left ventricular geometry and function alterations, underlying functional mitral regurgitation
