| | To overcome these limitations, intravascular ultrasound (IVUS) was developed towards the end of the 1980's and has been refined and its clinical importance assessed through the 1990’s 1. | | | The technique is similar to balloon angioplasty: a 6 to 8 French access sheath and guiding catheter are used through which a conventional angioplasty guidewire is passed to the distal part of the artery under scrutiny. | | | Future developments of IVUS-based technology are likely to allow on-line blood-flow measurement, forward views of chronic total occlusions, higher definition discrimination of stable and unstable plaques and the potential for ultrasound-based lysis of culprit plaques in acute myocardial infarction. |
