A rare case of inverted takotsubo cardiomyopathy led to fatal ventricular fibrillation in a 34-year-old woman. Autopsy confirmed this cardiac condition as the cause of death.
Area of Science:
- Cardiology
- Pathology
Background:
- Takotsubo cardiomyopathy (TCM) is a form of non-ischemic heart muscle dysfunction.
- Inverted takotsubo cardiomyopathy (iTCM) is a less common variant with basal ballooning.
Observation:
- A 34-year-old woman experienced out-of-hospital cardiac arrest with ventricular fibrillation.
- She developed recurrent polymorphic ventricular tachycardia and ventricular fibrillation in the hospital.
- Echocardiography revealed features consistent with iTCM.
Findings:
- The patient suffered a fatal episode of polymorphic ventricular tachycardia 24 hours after admission.
- Postmortem autopsy confirmed inverted takotsubo cardiomyopathy as the cause of death.
- This case highlights the potential for iTCM to cause life-threatening arrhythmias.
Implications:
- Understanding iTCM is crucial for diagnosing and managing patients with unexplained cardiac arrest.
- Pathological examination is vital for confirming iTCM in fatal cases.
- Further research into the mechanisms and management of iTCM is warranted.
