In this high-yield embryology video, I break down tracheoesophageal anomalies in a way that actually sticks for exams—especially esophageal atresia and tracheoesophageal fistula (TEF). I focus on what’s going wrong embryologically (abnormal separation of the foregut into the trachea and esophagus), and then I translate that into the classic clinical presentations you’re expected to recognize quickly. If you’ve ever mixed up which baby can’t pass an NG tube vs which one gets coughing/choking with feeds, this is the kind of framework I use to stop memorizing and start understanding. I also walk through the “why” behind the symptoms—like polyhydramnios when swallowing can’t happen, and aspiration-type symptoms when there’s an abnormal connection to the airway. My goal is to make you confident with the patterns: how to spot them, how to talk through them on a question stem, and what the most testable associations are. This is one of those topics that shows up everywhere (pre-clinical exams, Step-style questions, and pediatrics), so I’m intentionally keeping it concise, structured, and super exam-focused.
