# Transcatheter Closure of Complex Multifenestrated Atrial Septal Defect Using Three Septal Occluders: Is Three Too Many?

## TL;DR

This paper describes a complex case of closing a rare type of heart defect using three devices, showing it can be done successfully.

## Contribution

The paper presents a novel approach using three overlapping devices to close a complex heart defect.

## Key findings

- Transcatheter closure of a complex multifenestrated ASD was successfully achieved.
- Three overlapping Amplazter devices were used to manage the defect effectively.
- The procedure demonstrates the feasibility of using multiple devices for complex cases.

## Abstract

Atrial septal defects (ASDs) are a common form of adult congenital heart disease, with surgical or transcatheter closure being the mainstay of treatment in patients with hemodynamic or clinical complications. Transcatheter repair of secundum ASD is safe and effective. Complex secundum ASDs with multifenestrated defects pose a unique challenge to transcatheter repair. We report a successful but complex transcatheter closure of an ASD using three overlapping Amplazter devices.
