Echocardiographic studies of the left ventricular papillary muscles: structural variations as morphological predispositions for the development of cardiac biomechanical dysfunction

Abstract

The papillary muscles of the left ventricle are a key component of the subvalvular apparatus of the mitral valve. They play a crucial role in ensuring its stability during systole. Abnormalities in their anatomical structure or spatial organization can lead to changes in chordal tension and impaired coaptation of the mitral valve leaflets, which is one of the mechanisms underlying the development of valvular dysfunction. The study of the morphological characteristics of the papillary muscles is of great importance for clinical cardiology and cardiac surgery. Aim: To analyze the morphological variants of the papillary muscles of the left ventricle and assess their clinical significance based on echocardiographic findings and current literature data.
