If your doctor suspects you have tricuspid valve stenosis based on your history and physical exam, your doctor will likely order an echocardiogram (echo). An echo is a noninvasive test that uses sound waves to create a moving picture of the heart and will show pressure differences across the tricuspid valve as well as thickened valve leaflets (door-like structures that open to allow blood to flow out of the heart and close to prevent it from leaking backward), reduced valve movement, and an enlargement of the right atrium.
Other tests that may help to confirm a diagnosis of tricuspid valve stenosis include the following:
- Electrocardiogram (ECG or EKG) – This test measures the heart's electrical activity.
- Chest X-ray – This test uses a beam with a small amount of radiation to show images of the bones, heart and lungs, and blood vessels.
- Cardiac magnetic resonance imaging (MRI) – This test uses magnetic fields and radio waves to create detailed heart images.
- Liver function tests – These blood tests measure different enzymes, proteins, and other substances made by the liver.
