Septal papillary muscles (musculi papillares septales, MPS), similarly to other papillary muscles, areessential elements of the heart valvular system. Dam- age to their structure may lead to a considerablelife risk [5, 10]. Two groups of septal papillary muscles were distinguished, i.e. constant and variable. To the firstgroup belongs a muscle of the arterial cone (m. conti arteriosi or m. subarterialis, MCA) that always oc-curs and lies on the most anterior part of the sep- tum...

The term annulus fibrous is still used in anatomical and clinical terminology but  does not exist in anatomical nomenclature. This structure is proposed as an  anatomical substrate for circus movement of excitation...

The anatomy of the tricuspid valvar complex is highly sophisticated [13, 18–20], but understanding  of it may be helpful in the practice of cardiac surgery, especially in the partial transfer of leaflets of the tricuspid valve for mitral valve repairs [1, 2, 4]. The right atrioventricular valve region may be involved in severe cardiac malformations [5, 7–11, 15...

The tricuspid valve is heterogeneous [6] and is topographically related to the atrioventricular junctional area [3]. The shape of the right atrioventricular orifice evolves during life from a triangular to a more elliptical shape [7]...
