High-tech primary percutaneous coronary intervention.

Coronary recanalization by means of primary percutaneous coronary intervention is actually the treatment of choice in patients with ST-elevation myocardial infarction. However, conventional primary percutaneous coronary intervention still presents several limitations. In recent years sophisticated new devices and techniques have been developed to further improve the results of primary percutaneous coronary intervention: it seems to be appropriate to refer to their utilization using the definition "high-tech primary percutaneous coronary intervention". Although the study data available are controversial and clinical benefits have not clearly been shown, adjunctive devices have been used in many procedures. Patient and lesion selection appears to be crucial and the health economics as well as the safety of high-tech devices should be carefully evaluated.
