Retrograde Retrieval of a Novel Large Mitral Clip After Embolization Into the Left Ventricle

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Device Technology

Background:

• Severe secondary mitral regurgitation (SMR) poses significant challenges, particularly with complex left ventricular (LV) anatomy.
• Transcatheter edge-to-edge repair (TEER) is a treatment option for SMR, but challenging anatomies can lead to complications.
• Device embolization is a rare but serious adverse event during TEER procedures.

Observation:

• A novel large mitral clip embolized in a patient with severe SMR, LV dysfunction, dilated LV, and severely tethered mitral valve leaflets.
• The patient presented with anatomy considered challenging for standard TEER.
• The embolized clip necessitated a complex retrieval procedure.

Findings:

• Successful retrieval of the embolized novel large mitral clip was achieved.
• The description details the planning, technical challenges, and potential adverse events encountered during this bailout procedure.
• The case highlights the feasibility of clip retrieval in complex anatomical scenarios.

Implications:

• This case demonstrates a successful strategy for managing mitral clip embolization during TEER.
• It underscores the importance of meticulous planning and technical expertise in interventional cardiology.
• The findings contribute to the understanding of bailout procedures for TEER complications in challenging anatomies.
