3 leaflets ⬇️ + fibrous annulus + 2 papillary 💪🏽 + chordae tendinae + RA/RV ❤️

⬛️ Anterior 🍃 (largest)
◾️Posterior
▪️Septal (smallest)

(note: throughout #tweetorial, see image descriptions for more content) TV is largest and most apically displaced valve (normal TV area is between 7 and 9 cm^2).  Tricuspid annulus = complex nonplanar 3D structure w/low posteroseptal portion (towards the RV apex) & high anterolateral portion.TV has 2 distinct pap muscles (ant & post) + 3rd variable septal pap muscle. Largest pap = typically anterior w/chordae supporting ant & post leaflets. Posterior pap supports post + septal leaflets. Septal pap is variable: absent in up to 20% of normal patients or small, or multiple.Note attachments of leaflets/chordae to papillary muscles, RV free wall, moderator band.
