| Popis: | The aim was to study papillary muscles of the right ventricular septomarginal trabecula. Materials and methods: 98 formalinfixed normal hearts from human fetuses aged 17 to 28 weeks were studied by means stereomicroscope. Results. Muscles in such position were found to be in 55.1%. The free-standing papillary muscles predominated over the muscles of fixe type. The muscles had monolithic base, one belly and mostly one apex. Tendinous chords of these muscles entered only the septal cusp of the right atrioventricular valve. A potential clinical importance of the papillary muscles was mentioned. Conclusion. The papillary muscles situated at the septomarginal trabecula are proposed to regard as particular subgroup of septal papillary muscles. |
