See the lesion. Follow the rerouting. Predict the postoperative physiology. This module is built for residents who need to understand what the operation changes—not memorize a surgeon's technical manual.
Nine high-resolution operative illustrations paired with an explicit flow transformation and resident-level interpretation checkpoint. Select an operation to load its primary image.
Exactly 55 catalogued PTED treatment/procedure entries: four catheter interventions plus 51 treatment/surgical-repair topics. Several catalog entries intentionally point to the same lesion page because PTED groups multiple operations within one illustrated tutorial.
Eponyms are compressed routing instructions. Learn the blood-flow transformation first; the name then becomes useful shorthand rather than trivia.
Use the timeline to understand why older adults with CHD may have operations that residents rarely see performed today.
The original Blalock–Taussig operation, enabled by Vivien Thomas's experimental and technical work, established surgical palliation as a viable strategy for cyanotic CHD.
Glenn-type cavopulmonary connections and Senning's atrial switch showed that circulation could be rerouted rather than simply decompressed.
Atrial baffles and intracardiac ventricular rerouting expanded options for transposition and complex outflow anatomy, but created recognizable late systemic-RV, baffle, rhythm, and conduit problems.
Fontan and Baudet's concept ultimately evolved into modern total cavopulmonary connection for single-ventricle palliation.
Anatomic repair of d-TGA moved the LV back to systemic work and required reliable coronary transfer; it progressively displaced atrial-switch strategies for suitable neonates.
Staged reconstruction made survival possible for anatomy that previously had few surgical options, at the cost of a lifelong single-ventricle circulation.
Complex LVOT/arch obstruction with two usable ventricles could sometimes be treated with a biventricular LVOT-bypass strategy rather than defaulting to single-ventricle palliation.
Current congenital surgery increasingly emphasizes valve preservation, growth potential, catheter-surgical hybrid pathways, lower reintervention burden, and lifetime physiology rather than survival of the index operation alone.
Use these short teaching summaries with the Atlas, PTED animations, and eponym guide before testing yourself.
Review the assessment foundations, then reason from anatomy and physiology. Immediate explanations are deliberate retrieval practice, not merely a score screen.
It is not an operative manual, a substitute for a congenital cardiac surgeon, a dosing guide, or a patient-specific risk calculator. Surgical timing and technique vary with detailed anatomy, institutional strategy, era, and patient condition. The primary Atlas images encode routing concepts rather than patient-specific operative views.
