Morphology of the papillary muscles and the chordae tendineae of the ventricles of adult human hearts
M Hosapatna, A DSouza, VH Ankolekar - Cardiovascular Pathology, 2022 - Elsevier
Introduction The papillary muscles (PM) play a vital role in atrioventricular (AV) valve
function. The PM and their chordae tendineae (CT) regulate the closure of the AV valve
during systole. The present study was undertaken to categorize the PM based on their
shapes and variant patterns and CT based on their types and the branching pattern.
Methods This study included formalin-fixed ten adult cadaveric heart specimens. We
observed the number, shape, length, breadth, pattern, and presence of extra PM. The …
