To diagnose these disorders, healthcare providers typically rely on a combination of clinical evaluation, imaging studies, and specific diagnostic criteria. Below are the key criteria and methods used in the diagnosis of nonrheumatic tricuspid valve disorders.

Clinical Evaluation

Symptoms

Patients may present with a range of symptoms that can indicate tricuspid valve disorders, including:
- Fatigue: Often due to reduced cardiac output.
- Swelling: Edema in the legs, abdomen, or other areas due to fluid retention.
- Palpitations: Irregular heartbeats or a sensation of a racing heart.
- Shortness of Breath: Particularly during exertion or when lying flat, which may indicate heart failure.

Medical History

A thorough medical history is essential. Clinicians will inquire about:
- Previous heart conditions or surgeries.
- Family history of heart disease.
- Symptoms of heart failure or arrhythmias.
- Any history of endocarditis or other infections.

Diagnostic Imaging

Echocardiography

Echocardiography is the primary diagnostic tool for assessing tricuspid valve disorders. It provides detailed images of the heart's structure and function. Key aspects evaluated include:
- Valve Structure: Assessment of the tricuspid valve for abnormalities such as stenosis (narrowing) or regurgitation (leakage).
- Chamber Size: Evaluation of the right atrium and ventricle for dilation, which can occur due to increased pressure or volume overload.
