Echocardiographic Outcomes With Transcatheter Edge-to-Edge Repair for Degenerative Mitral Regurgitation in Prohibitive Surgical Risk Patients

JACC Cardiovasc ImagingPublished

  • Secondary analysis of the CLASP IID randomised trial
  • independent echocardiographic core laboratory

Authors' conclusion

Treatment with PASCAL and a smaller flail gap were significant factors in sustaining MR ≤1+ to 6 months.

Study context

Population
Patients at prohibitive surgical risk with significant symptomatic degenerative mitral regurgitation (MR)randomized
Participants
180 patients
Comparison
PASCAL vs MitraClip for mitral transcatheter edge-to-edge repair (M-TEER)
  • PASCALn = 117
  • MitraClipn = 63reference
Primary endpoint
Echocardiographic outcomes and baseline variables associated with residual MR ≤1+

Primary result

Residual MR ≤1+

Adjusted odds ratio

2.72

95% CI 1.08–6.89

By group

PASCAL vs MitraClip
adjusted OR 2.72 (95% CI 1.08–6.89)

As reported in the abstract

Smaller flail gap: MR ≤1+ at discharge, adjusted OR
0.70 (95% CI 0.50-0.99)
Smaller flail gap: sustained MR ≤1+ to 6 months, adjusted OR
0.76 (95% CI 0.60-0.98)

Further findings

MR ≤2+ at discharge

All patients achieved MR ≤2+ at discharge
