# Progress in the treatment of subarterial ventricular septal defect

## TL;DR

This paper discusses the treatment of a specific heart defect in children that requires timely intervention due to its complex anatomy and limited self-healing ability.

## Contribution

The paper summarizes current surgical approaches and outcomes for treating a specific congenital heart defect.

## Key findings

- Doubly committed ventricular septal defect (dcVSD) has low self-healing potential and requires timely treatment.
- Interventional treatment via femoral vein radiation is challenging and has limited application.
- Extracorporeal bypass and transthoracic occlusion are the main treatment methods for dcVSD.

## Abstract

Ventricular septal defect is the most common congenital heart disease in children. Among them, doubly committed ventricular septal defect (dcVSD) can be accompanied by aortic valve lesions in the early stage due to its particular anatomical structure. With its low self‐healing, once diagnosed, it needs to be treated timely. Currently, the interventional treatment of proper femoral vein radiation intervention in the department of cardiology is challenging to operate. The scope of application is small, and dcVSD is mainly treated by extracorporeal bypass and transthoracic occlusion. The indications, surgical experience, and prognosis of surgery are summarized.
