CT-Guided Preprocedural Assessment of TEER in Mitral Prolapse: When Calcification Limits TEE

Key Result

CT-guided preprocedural assessment facilitates transcatheter edge-to-edge repair planning in mitral prolapse when severe leaflet calcification limits transesophageal echocardiography.

Key Points

To evaluate how CT imaging can aid in assessing severe mitral leaflet calcification prior to TEER.
Utilized CT imaging to assess mitral valve structure and calcification severity.
Compared CT findings with transesophageal echocardiographic results.
Evaluated implications of findings for procedural planning.
CT imaging provided clearer insights into leaflet calcification compared to TEE.
Impaired TEE assessment was common in cases of severe calcification.
Successful procedural planning was enhanced by CT-guided evaluations.

Structured PICO

Does CT-guided preprocedural assessment improve procedural planning for TEER in patients with mitral prolapse and severe calcification limiting TEE?

Population

Patients undergoing transcatheter edge-to-edge repair (TEER) for mitral prolapse with severe mitral leaflet calcification limiting transesophageal echocardiography

Intervention

CT-guided preprocedural assessment

CT imaging may serve as a useful adjunct for preprocedural planning of TEER in mitral prolapse when severe calcification limits standard TEE assessment.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

Transcatheter edge-to-edge repair (TEER) relies on accurate preprocedural imaging. Severe mitral leaflet calcification may impair transesophageal echocardiographic assessment and complicate procedural planning.
