AB  - BACKGROUND: Intravascular ultrasound (IVUS) provides better assessment of vessel 
      size, lesion length and plaque characteristics. There is paucity of data 
      regarding the impact of IVUS on stenting pattern during primary percutaneous 
      intervention (PCI) for ST elevation myocardial infarction (STEMI). METHODS: We 
      included patients with STEMI undergoing IVUS-guided primary PCI. Diagnostic 
      angiograms were analysed by two different operators who were not part of 
      procedure. They were asked to formulate a treatment plan which included choice of 
      stent diameters, length and number of stents based on angiographic assessment 
      alone. The data were then compared with actual metrics derived from IVUS 
      evaluation. RESULTS: Sixty-two patients were included. Left anterior descending 
      artery was involved in 38/62(61.3%) cases. Mean stent diameters assessed by 
      angiogram were 2.94 +/- 0.4 mm and 3.01 +/- 0.32 mm by cardiologist 1 and 2, 
      respectively. IVUS-derived mean stent diameter was 3.5 +/- 0.65 mm (p < 0.001). 
      Mean stent length was 42.29 +/- 19.29 mm by IVUS evaluation; while angiographically 
      assessed values were 33.53 +/- 11.53 (cardiologist 1) and 35.24 +/- 12.97 mm 
      (cardiologist 2) with a mean difference of 8.76 mm and 7.05 mm respectively 
      (p < 0.001). Mean number of stents by IVUS evaluation was 1.42 +/- 0.56, while by 
      angiographic evaluation were 1.11 +/- 0.37 and 1.13 +/- 0.34 respectively 
      (p < 0.001). CONCLUSIONS: There was significant difference between IVUS derived 
      and angiographically assessed culprit vessel metrics in patients undergoing 
      primary PCI. Clinical outcomes of this discrepancy need further studies.
