The papillary muscles as shock absorbers of the mitral valve complex. An experimental study.
OBJECTIVE Although it is known that the papillary muscles ensure the continuity between the left ventricle (LV) and the mitral apparatus, their precise mechanism needs further study. We hypothesize that the papillary muscles function as shock absorbers to maintain a constant distance between their tips and the mitral annulus during the entire cardiac cycle. MATERIALS AND METHODS Sonomicrometr...
متن کاملMorphological Study of Tricuspid Valve And Its Variations in Adult Human Hearts
Introduction: The tricuspid valve is a heterogeneous structure with great variability in its structure and has remained unexamined despite intense interest in cardioanatomy. The tricuspid valve complex is of great clinical importance in the light of progress in cardiosurgery and the development of novel operating techniques. Materials and methods: The present work was done by dissecting 42 form...
متن کاملProvision of tricuspid valve leaflets by septal papillary muscles in the right ventricle of human and other mammal hearts.
Leaflets of the tricuspid valve are provided by tendinous cords extending from the papillary muscles. The situation is complicated with the septal muscles, which generally occur in two groups, one as constant musculus coni arteriosi and the second as other variable septal muscles. We tested whether there is a variability in the provision of the tricuspid valve in different taxonomical groups of...

15 صفحه اولP.Dharmendra et al CLINICALLY SIGNIFICANT ANATOMICAL VARIATIONS OF THE LEFT CORONARY ARTERY IN HUMAN CADAVERIC HEARTS
The anatomy of the coronary vessels has been described in detail for atleast 3 centuries. Detailed appreciation of the normal origin, course, branching and myocardial distribution of these vessels is vital so that variations of the normal anatomy can be more easily recognized and applied to clinical practice. Knowledge of normal anatomy and variations in the branching pattern of coronary arteri...
