# Case Report: Diagnosis and treatment of congenital right atrial dissection associated with atrial aneurysm

## TL;DR

This case report describes a rare congenital heart condition diagnosed in a fetus and successfully treated with surgery in infancy.

## Contribution

The novelty lies in the first reported case of congenital right atrial dissection with atrial aneurysm diagnosed prenatally and treated surgically in infancy.

## Key findings

- The condition was diagnosed in the fetal period and successfully treated with surgery under extracorporeal circulation.
- The infant recovered and was discharged, but the optimal timing for surgical intervention remains unclear.

## Abstract

Spontaneous atrial dissection and atrial aneurysm are extremely rare conditions. This may be the first reported case diagnosed in the fetal period and successfully treated with surgery under extracorporeal circulation in infancy. Although the infant in this case underwent surgery successfully, recovered, and was discharged, the optimal timing for surgical intervention in such cases remains unclear. This report aims to provide a treatment reference for similar cases.
