Cardiac Troponin I Elevation After Orogenital Sex During Pregnancy

Venous air embolism due to orogenital sex in pregnancy is an uncommon clinical event. A previously healthy, 29-week pregnant woman presented to the emergency room unconscious 1 hour after engaging in orogenital sex with her partner. The cardiology service was consulted due to troponin elevation. Assessment was that the patient had likely suffered an air embolism with associated troponin leak. Although a rare clinical event, air embolism from air insufflation of the vagina can result in troponin elevation and should be considered in the differential diagnosis in pregnant patients with a history of orogenital sex.
