Authors' objectives:

1. To identify the literature on intravascular ultrasound (IVUS) for guiding coronary interventions, and to synthesise evidence about outcomes compared with outcomes when IVUS guidance has not been used.

2. To use this evidence, together with other information about costs and outcomes, to model the cost effectiveness of IVUS guidance.

3. To synthesise the evidence on the reproducibility of measurements of cross-sectional area made using IVUS.

Authors' results and conclusions: Only one study on IVUS-guided angioplasty satisfied the inclusion criteria, and there were no studies on IVUS-guided atherectomy or other IVUS-guided interventions that satisfied the inclusion criteria. Of the 15 articles on IVUS-guided stenting that satisfied the inclusion criteria, seven presented data on outcomes at 6 months post-intervention. The angiographic restenosis rate was 16 +/-1%. This compared with 24 +/-2% derived from five articles on stenting without IVUS guidance. Data for follow-up periods longer than 6 months were presented in only two studies. The smallest changes in cross-sectional area that could be measured were 1.6 mm2 by a single observer and 1.9 mm2 by different observers.
Authors' recommendations: The evidence available is too weak for there to be any reliable implications for clinical practice.
