Brief Summary:
Attenuated plaque ≥ 5mm by intravascular ultrasound(IVUS) was reported to be high risk for distal embolism in Acute coronary syndrome(ACS). The purpose of this study is to assess the effect of thrombus aspiration catheter and distal protection device (filter wire; Filtrap™) in the aforementioned subgroup of patients at high risk for distal embolism.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Procedure: Filtrap™ + Thrombus aspiration catheter Procedure: Thrombus aspiration catheter Not Applicable

Primary Outcome Measures :
  1. Incidence of no-reflow/slow-flow phenomenon after percutaneous coronary intervention (PCI) [ Time Frame: a day ]

Secondary Outcome Measures :
  1. Rise in CK-MB and troponin I or T the next morning after PCI (Peak of CK too in case of ST-segment elevation myocardial infarction ) [ Time Frame: a day ]
  2. Incidence of clinical events including mortality, major adverse cardiac events, and Hospitalization for heart failure [ Time Frame: 10months ]
  3. Improvement of Thrombolysis in Myocardial Infarction (TIMI) flow grade compared with baseline [ Time Frame: 8-12months ]
  4. TIMI flow grade [ Time Frame: 8-12months ]
  5. Corrected TIMI frame count [ Time Frame: 8-12months ]
  6. Myocardial blush grade [ Time Frame: 8-12months ]
  7. Incidence of any revascularization [ Time Frame: 8-12months ]
  8. Incidence of stent thrombosis [ Time Frame: 8-12months ]
  9. Plaque protrusion by IVUS inside the stent [ Time Frame: 8-12months ]
