SCAI Hildner Lecture highlights innovative techniques for plaque imaging

...nd time-consuming to use--they require threading a catheter into the arteries of the heart--but they have the potential to provide a wealth of anatomic and functional information. For example, virtual histology uses intravascular ultrasound to re-create a picture of the plaque, whereas optical computed tomogr...

SCAI Founders' Lecture traces impressive progress in interventional cardiology

...ened procedure times. Development of the perfusion catheter meant that interventional cardiologists could re-establish blood flow to the heart and stabilize patients in case of a sudden arterial blockage. Bare metal stents and new anti-clotting medications reduced the chances of sudden arterial closure. Howe...
