# Interventional closure of artificial vascular anastomotic fistula after aortic replacement: a case report

## TL;DR

A patient who had aortic replacement surgery developed a heart fistula, which was successfully closed using a minimally invasive procedure.

## Contribution

This case report presents a successful interventional approach to closing an anastomotic fistula after aortic replacement.

## Key findings

- The patient had a successful transcatheter closure of an ascending aorta-right atrial fistula.
- Post-procedure, no abnormal shunt was detected, and short-term outcomes were satisfactory.
- The procedure was effective in treating chronic heart failure caused by the fistula.

## Abstract

Two years ago, the patient suffered from type A aortic dissection. As a result, partial aortic dissection artificial vascular replacement and partial aortic arch artificial vascular replacement were performed. Six months after the operation, an anastomotic fistula in the ascending aorta was detected, which subsequently progressed to chronic heart failure of New York Heart Association (NYHA grade) class III. After eliminating the operation - related contraindications, the patient successfully had the fistula occluded through transcatheter ascending aorta - right atrial fistula in our hospital. After the operation, no abnormal shunt was found, and the short - term treatment effect was satisfactory.
