Season 6 Episode 9

New History

New History is curated around five confirmed medical threads: Casey's ALCAPA and Takeuchi repair, Dr. Singer's normal pressure hydrocephalus and shunt, Sheldon Morris's obstructive jaundice from clipped bile duct, Gary Clark's anterior MI and angioplasty, and an ER patient's sick sinus syndrome requiring pacemaker care.

Medical Cases in This Episode

These are the patient stories worth unpacking. Open any case for the real-world medicine, what the episode shows, what it leaves out, and source-backed context.

5 cases identified

Case 1

Casey: ALCAPA, Cardiac Asthma, and Takeuchi Repair

Casey's wheezing is cardiac asthma from a rare congenital coronary anomaly.

Episode shows: Casey has anomalous left coronary artery from the pulmonary artery and cardiac asthma. Teddy performs a Takeuchi repair with Cristina assisting, and Casey stabilizes after surgery.
Clinical takeaway: The case is relevant because respiratory symptoms can come from cardiac disease, especially in rare congenital coronary anomalies.

Case 2

Dr. Singer: Normal Pressure Hydrocephalus and Shunt

A retired surgeon's decline is reframed as potentially treatable normal pressure hydrocephalus.

Episode shows: Dr. Singer is brought in by her daughter after cognitive and functional decline. Derek diagnoses normal pressure hydrocephalus and plans a shunt procedure, with Meredith scrubbing in.
Clinical takeaway: The case is relevant because NPH can resemble dementia but may improve with shunting in selected patients.

Case 3

Sheldon Morris: Obstructive Jaundice and Bile Duct Injury

Sheldon's jaundice comes from a clipped common bile duct after cholecystectomy.

Episode shows: Sheldon develops obstructive jaundice after cholecystectomy. Bailey determines his common bile duct was clipped, and the case proceeds to surgery after Charles delays disclosing the finding.
Clinical takeaway: The case is relevant because post-cholecystectomy bile duct injury requires prompt recognition and transparent team communication.

Case 4

Gary Clark: Anterior Myocardial Infarction and Angioplasty

Gary Clark's chest pain is an anterior MI treated with angioplasty by Teddy.

Episode shows: Gary Clark arrives with chest pain and his wife Allison. Teddy diagnoses an anterior myocardial infarction and performs angioplasty, after which Allison thanks her.
Clinical takeaway: The case is relevant because acute chest pain needs rapid MI recognition and cath-lab level intervention.

Case 5

ER Patient: Sick Sinus Syndrome and Pacemaker

A dizzy ER patient is diagnosed with sick sinus syndrome and needs a pacemaker.

Episode shows: One of Teddy's ER patients is dizzy and diagnosed with sick sinus syndrome. The planned treatment is pacemaker placement.
Clinical takeaway: The case is relevant because dizziness can reflect a clinically important bradyarrhythmia.

Episode Summary

New History introduces Teddy Altman through cardiothoracic judgment while pairing her with several diagnostic lessons. Casey's rare ALCAPA explains cardiac asthma and needs Takeuchi repair. Dr. Singer's decline becomes normal pressure hydrocephalus rather than ordinary dementia. Sheldon's jaundice reveals a clipped bile duct after cholecystectomy. Gary Clark's chest pain and another ER patient's dizziness give Teddy rapid cardiac triage moments.

Differential Diagnosis and Testing Logic

Casey's wheezing/dyspnea requires cardiac evaluation rather than assuming asthma. Dr. Singer's decline requires considering reversible NPH alongside dementia. Sheldon's jaundice requires post-cholecystectomy obstruction and bile duct injury workup. Gary's chest pain requires rapid MI evaluation. The dizzy ER patient requires ECG/telemetry for rhythm causes such as sick sinus syndrome.

Medical Accuracy Review

The episode is strongest when it shows diagnostic reframing: cardiac asthma is not asthma, NPH is not automatically dementia, and jaundice after cholecystectomy can be iatrogenic obstruction. It compresses congenital cardiac imaging, NPH testing, bile duct injury repair planning, ACS protocols, pacemaker workup, and follow-up.
