Shark Fin Sign in a Patient with Sepsis-induced Cardiomyopathy Associated with Retained Placenta: A Case Report and Review of the Literature

Retained placenta can lead to septic shock; however, sepsis-induced cardiomyopathy (SICM) due to retained placenta has not been reported previously. This report presents a rare case of SICM following septic shock due to retained placenta after miscarriage in a 40-year-old woman, accompanied by the &...

Description
Summary:Retained placenta can lead to septic shock; however, sepsis-induced cardiomyopathy (SICM) due to retained placenta has not been reported previously. This report presents a rare case of SICM following septic shock due to retained placenta after miscarriage in a 40-year-old woman, accompanied by the "shark fin sign" on an electrocardiogram, a pattern typically linked to myocardial ischemia. She experienced ventricular tachycardia and required venoarterial extracorporeal membrane oxygenation; however, she was successfully treated. We also reviewed previous cases of shark fin sign in patients without myocardial infarction. A review showed that half of the cases experienced lethal arrhythmias, even without myocardial infarction.
