Insights

Trans-catheter aortic valve replacement (TAVR) can cause guide-wire thrombosis, risking stroke. A novel aspiration thrombectomy technique successfully removed a large thrombus during TAVR, preventing potential neurological events in a high-risk patient.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Device Technology

Background:

  • Trans-catheter aortic valve replacement (TAVR) is a critical option for severe symptomatic aortic stenosis in high-risk patients.
  • Guide-wire thrombosis during TAVR is a known complication with potential for embolic events, including stroke.

Observation:

  • A large, >1cm thrombus was identified on the intra-ventricular guide-wire during a TAVR procedure using trans-esophageal echocardiogram (TEE).
  • Despite thrombus detection, balloon aortic valvuloplasty and valve deployment were successfully completed.

Findings:

  • A novel aspiration thrombectomy technique was employed using a guiding catheter and continuous suction.
  • The guide-wire and thrombus were safely retrieved as a single unit, preventing embolization.

Implications:

  • This case demonstrates a new method for managing guide-wire thrombosis during TAVR.
  • Successful thrombus retrieval may reduce the risk of neurological complications, such as stroke, in TAVR patients.
  • Further experience with TAVR necessitates strategies to mitigate procedural complications like thrombus formation and embolization.
