Chapters

1. One Trunk, Two Mouths, One Wall
   acoustic guitar, lyrical music, hand clapping, no drums · 3:58
   Explore the foundational anatomy of truncus arteriosus, where a single great vessel overrides the ventricular septum to supply systemic, pulmonary, and coronary circulation, and learn how the Collett-Edwards classification system distinguishes Type II by its posterior and posterolateral pulmonary artery origins.
2. Two Ostia, One Whispered Root
   spoken word poetic, piano jazz · 4:26
   Explore the intricate branching pattern of Type II Truncus Arteriosus, where separate pulmonary artery ostia arise close together from the posterior-left wall of the truncal vessel—learn to identify this subtle anatomical variant and understand why measuring ostial spacing matters for accurate diagnosis.
3. One Root, Two Mouths
   melodic piano, duet male female · 4:02
   Explore how a single arterial trunk disrupts normal blood flow separation in newborns, driving pulmonary overcirculation as lung resistance falls, and learn to recognize the early clinical signs—like feeding difficulty and labored breathing—that signal this dangerous physiological cascade.
4. Single Button, One Clean Snip
   piano, classical, rap · 3:31
   Explore the critical surgical timeline for repairing Type II Truncus Arteriosus, learning why the four-to-six week window matters and how the close proximity of shared pulmonary origins shapes the operative approach.
5. One Root, Two Disguises
   acoustic guitar, lyrical music, hand clapping, no drums · 3:32
   Explore the surgical decision-making behind truncal valve repair versus replacement, plus the escalating challenges of conduit reinterventions as patients with Type II Truncus Arteriosus grow, learning how tissue quality and regurgitation severity guide each critical choice.
6. Spiral Roots, Steady Hands
   acoustic guitar, lyrical music, hand clapping, no drums · 3:52
   Hands-on training in reading angiograms for Type II Truncus Arteriosus, guiding listeners through rotating 3D renders to trace the twin pulmonary roots and precisely mark ostium measurements and take-off angles essential for surgical planning.
7. One Vessel Where Two Should Divide
   melodic piano, duet male female · 4:48
   Trace the origins of truncus arteriosus classification from Wilson's 1798 discovery through the pathologists who spent the 19th century meticulously documenting this rare cardiac anomaly, and learn how their anatomical observations laid the groundwork for the Type II diagnostic criteria used today.
8. One Trunk, Two Futures
   spoken word poetic, piano jazz · 4:37
   Trace the evolution of surgical strategies for Type II Truncus Arteriosus, from early pulmonary artery banding attempts to the development of complete repair techniques, and discover why the anatomy of dual pulmonary branches demanded innovative solutions beyond simple flow restriction.
9. One Long River Through the Trunc
   chill, uk spoken poetry, jazz, bass and piano, slow · 4:28
   Trace the 1949 Collett and Edwards classification system back to its roots in limited autopsy data, and learn how small sample sizes and selection bias still shape the way truncus arteriosus is categorized today.
10. One Trunk, Two Branches, One Truth
    piano, classical, rap · 3:32
    Dive into the anatomy of Type II Truncus Arteriosus, where a single arterial trunk and looping pulmonary branches challenge diagnosis, and discover how echo and CT imaging work together to map a newborn's complex heart.
11. One Trunk, Three Branches
    acoustic guitar, lyrical music, hand clapping, no drums
    Wraps up the curriculum with a review of Type II Truncus Arteriosus, honing in on how the pulmonary branches arise together from the shared arterial trunk and the Collett-Edwards and Van Praagh classification systems learners need to master for their written exam.
