TV inflow and TDI
TV inflow and tricuspid annular TDI fields provide RV diastolic and loading-condition context.
Clinically reviewed 24 May 2026 · EchoRapp clinical content
Simple approach
Use E, A, E/A, deceleration time, e’, a’, e’/a’, and E/e’ as supportive right-sided diastolic context rather than as a standalone verdict.
Detailed tutorial
Tricuspid inflow and annular TDI are loading dependent. They are most useful when interpreted with rhythm, respiration, RAP estimate, hepatic vein flow, and right atrial size.
| Group | Measurements |
|---|---|
| Inflow | E, A, E/A, deceleration time |
| TDI | e’, a’, e’/a’, E/e’ |
Info
Average representative beats and consider respiratory variation, especially in atrial arrhythmia or marked right-sided pressure changes.
