# Cardioversion-Induced Takotsubo Cardiomyopathy

## TL;DR

A 77-year-old woman developed takotsubo cardiomyopathy after a cardioversion procedure for atrial fibrillation, but her heart function improved after treatment.

## Contribution

This case report highlights a rare instance of takotsubo cardiomyopathy triggered by cardioversion rather than typical stressors.

## Key findings

- The patient developed takotsubo cardiomyopathy four days after cardioversion.
- Her symptoms resolved within three days with IV diuretic treatment.
- Echocardiogram showed significant improvement in cardiac function before discharge.

## Abstract

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or "broken heart syndrome," is a rare and reversible condition characterized by transient left ventricular dysfunction. It is typically triggered by acute emotional or physical stressors. Here, we present a unique case of TCM occurring in a 77-year-old woman following cardioversion for persistent and symptomatic atrial fibrillation. The patient underwent uncomplicated cardioversion with recent imaging showing intact global systolic function. She presented four days post-procedure for chest pain, shortness of breath, and peripheral edema. A repeat echocardiogram showed a marked decrease in cardiac function evidenced by an ejection fraction of 20-25%. The patient was readmitted and managed with IV diuretics. Symptoms resolved within three days and the patient showed improved cardiac function on imaging prior to discharge.
