FETCH™2 Aspiration Catheter Case Study

Manual aspiration thrombectomy of a native coronary artery.

Patient History

  • 64 year old male
  • Former smoker
  • History of hypertension
  • Presented with chest pressure relieved by nitroglycerine in the emergency department
  • EKG demonstrated less than 1 mm of ST depression in the anterior leads
  • Subsequently the troponin increased to 7.23 ng/mL
  • Patient was referred for coronary angiography

Diagnostic Angiogram

  • Initial angiogram showed TIMI 3 flow
  • Pre-wiring, the thrombus grade was 3
  • The left main and left anterior descending arteries had no significant lesions
  • The first obtuse marginal had a sub-total long thrombotic lesion in the proximal vessel (Cine 1: Diagnostic Angiogram)
  • The RCA had a 70% proximal lesion and a 70% mid-vessel lesion


  • Patient was anticoagulated with heparin
  • Post wiring, the thrombus grade was 3 (Cine 2: Post Wire)
  • The obtuse marginal was treated with manual aspiration thrombectomy utilizing the FETCH2 Aspiration Catheter
  • A moderate amount of red thrombus was removed (Cine 3: FETCH2)
  • Post FETCH2, the thrombus grade was 2
  • Angiographic improvement was observed post thrombectomy (Cine 4: Post FETCH2)

Definitive Treatment

Following PTCA with stenting and post-dilatation, the final thrombus grade was 0 with TIMI flow 3 (Cine 5: Definitive Treatment).

Physician Commentary

  • Percutaneous coronary intervention in thrombotic lesions may result in distal embolization, slow flow, and possibly re-infarction
  • Removal of thrombus prior to intervention may prevent these complications
  • Manual aspiration thrombectomy is a simple and effective method to treat patients with thrombotic coronary lesions
  • This case demonstrates how the removal of small-to-moderate thrombus with the FETCH2 catheter can facilitate the definitive treatment and reestablish flow
