Summary

This observational study will analyze data from 3,000 people with complex congenital heart disease who have had or will have heart surgery in China. Researchers aim to identify key risk factors affecting recovery and build a quality control system to improve surgical care. Participants' medical records and follow-up data will be collected and combined into a registry.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could lead to better surgical care and recovery for people with complex congenital heart disease in China.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly test a new therapy. Results may not apply outside China or to all patient groups.
