Season 13 Episode 15

Civil War

Civil War is best curated as Sister Agnes's aneurysm clipping before heart surgery, April's patient's colovesical fistula closure, and Gus Endris's hypoplastic left heart syndrome with a Norwood-versus-transplant decision and secret UNOS listing.

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.

3 cases identified

Case 1

Sister Agnes: aneurysm clipping before heart surgery

Sister Agnes needs an aneurysm clipped before a planned heart surgery can proceed.

Episode shows
Sister Agnes is in the hospital for heart surgery, but she also has an aneurysm that needs to be clipped first. The aneurysm surgery goes well, and she is ready for her heart surgery afterward.
Clinical takeaway
The case shows staged surgical planning where one risk must be addressed before a second operation.

Case 2

April's patient: colovesical fistula closure without reconstruction

Catherine consults on April's patient and says the colovesical fistula has closed on its own, avoiding abdominal reconstruction.

Episode shows
April's patient has a colovesical fistula. Catherine consults and says the fistula closed on its own, so abdominal reconstruction is not needed.
Clinical takeaway
The case is a focused surgical reassessment: if a fistula has truly closed, the team may avoid a larger reconstruction.

Case 3

August Endris: hypoplastic left heart syndrome, Norwood debate, and transplant

Gus is diagnosed with hypoplastic left heart syndrome after a newborn murmur, then receives a heart transplant after a disputed Norwood-versus-transplant decision.

Episode shows
August "Gus" Endris has a murmur after birth. After exam and tests, he is diagnosed with hypoplastic left heart syndrome. Nathan wants to wait for a heart transplant, while Alex wants to do a Norwood procedure. Both options are presented to the parents, but Na...
Clinical takeaway
The case combines newborn congenital heart disease, surgical alternatives, transplant allocation, parental consent, and clinician boundary violations.

Episode Summary

Civil War has three concrete medical threads. Sister Agnes needs an aneurysm clipped before planned heart surgery and is ready for the cardiac operation after successful clipping. April's patient has a colovesical fistula that Catherine says closed on its own, avoiding abdominal reconstruction. August "Gus" Endris has a murmur after birth, is diagnosed with hypoplastic left heart syndrome, and receives a heart transplant after a disputed Norwood-versus-transplant decision and Nathan's secret UNOS listing.

Differential Diagnosis and Testing Logic

Sister Agnes's care would require clarifying aneurysm location, rupture risk, cardiac diagnosis, and operative sequencing. April's fistula case would require confirming closure and cause, including diverticular disease, inflammatory bowel disease, malignancy, prior surgery, radiation injury, infection, or trauma. Gus's newborn murmur requires urgent congenital-heart evaluation, including hypoplastic left heart syndrome and other critical defects such as coarctation, aortic stenosis, transposition, pulmonary atresia, tetralogy of Fallot, and ventricular septal defect.

Medical Accuracy Review

The episode gives strongest detail for Gus because it includes presentation, diagnosis, treatment alternatives, consent conflict, listing, and transplant. Sister Agnes and April's patient are supported but thinner. This review avoids adding aneurysm anatomy, heart diagnosis, fistula imaging, Gus's oxygen saturation, echocardiogram findings, prostaglandin use, transplant criteria, operative details, or postoperative outcome.
