This study is looking at people with Congenital Heart Disease (a heart condition present at birth) who are already scheduled to have a Cardiac Catheterization (a procedure where a thin tube is inserted into a blood vessel to reach the heart). During this procedure, an additional test called invasive Cardiopulmonary Exercise Testing (CPET) will be performed. The main goal is to see how well these tests, done both at rest and during exercise, can find problems with blood flow in the heart. Researchers also want to compare these invasive tests to non-invasive (Doppler-derived) tests and understand how they relate to the severity of your heart condition. You can join if you are 18 or older, have Congenital Heart Disease, and are already having a clinically necessary Cardiac Catheterization. The study aims to enroll 200 participants.

Study design

This is an interventional study, meaning participants will receive a specific intervention. It plans to enroll 200 participants.

What's involved

You will undergo a standard Cardiac Catheterization, and during this procedure, invasive Cardiopulmonary Exercise Testing (CPET) will also be performed.

Compensation

Not stated in the trial record.

Follow-up

The primary measurements will be taken at Baseline (during the procedure).
