Predictors of Left Atrial Compliance and V-Wave Response in Patients Undergoing Transcatheter Mitral Valve Therapy
Authors' conclusion
Low LA strain and prior AF intervention or LAA ligation may predict low invasive LA compliance and limited V-wave reduction after TMVT.
Study context
- Population
- Patients undergoing transcatheter edge-to-edge repair or valve-in-valve TMVR at the Cleveland Clinic, 2019–2023
- Participants
- 255 patients
- Exposure
- Compliant vs noncompliant left atrial (LA) in patients undergoing transcatheter mitral valve therapy (TMVT)
- Compliant LAn = 107reference
- Noncompliant LAn = 148
- Outcome
- Noninvasive predictors of invasive LA compliance and V-wave response
