Right atrial and right ventricular strain: prognostic value depends on the severity of tricuspid regurgitation
Authors' conclusion
RA and RV strain are independently correlated with echocardiographic and invasive measures of cardiac function. Moreover, preserved RA and RV strain is likely associated with better clinical outcomes.
Study context
- Population
- Patients with tricuspid regurgitation (TR) undergoing same-day echocardiography and right heart catheterization, 2018–2023
- Participants
- 262 patients
- Exposure
- Preserved vs impaired right atrial (RA) and right ventricular (RV) strain
- Outcome
- HF-related death or hospitalization, whichever came first
- Follow-up
- Mean 34 ± 15 months
Methodological detailsconsecutive patients
- Consecutive patients
