Key result
A continuous stellate ganglion block successfully controlled angina and prevented further defibrillation episodes in a pregnant patient with refractory ventricular fibrillation and Prinzmetal angina.
Case Report (n=1)
Continuous stellate ganglion block may be an effective and safe intervention for managing refractory ventricular fibrillation and Prinzmetal angina during pregnancy.

May offer a temporizing option for refractory VF in pregnancy; hypothesis-generating and requires prospective validation.
A patient with a history of Prinzmetal angina, refractory ventricular fibrillation, cardiac arrest with an implantable cardioverter-defibrillator, and obesity presented to the emergency department at 17 weeks gestational age with a chief complaint of angina and multiple episodes of defibrillation. A T3/4 thoracic epidural was placed to assess the effectiveness of a partial chemical sympathectomy in alleviating symptoms of angina as well as decreasing the amount of defibrillation episodes. Once this proved to be beneficial in accomplishing both of these goals, a more specific approach was designed. A continuous stellate ganglion block was then placed controlling both her angina and preventing further episodes of defibrillation long enough for her pregnancy to progress beyond 24 weeks gestational age.

Scalercio et al. (2018) conducted a case report in Prinzmetal angina and refractory ventricular fibrillation during pregnancy (n=1). Continuous stellate ganglion block was evaluated on Alleviation of angina symptoms and decrease in defibrillation episodes. A continuous stellate ganglion block successfully controlled angina and prevented further defibrillation episodes in a pregnant patient with refractory ventricular fibrillation and Prinzmetal angina.
