Case in brief

A patient with functionally significant stenosis at the ostium of the left anterior descending artery underwent directional coronary atherectomy guided by optical coherence tomography (OCT). To orient the atherectomy device, the operators adapted the intravascular ultrasound tip-detection method using a second guidewire with a curved tip. Matching the guidewire’s fluoroscopic direction to the 3 o’clock position on the OCT cross-section provided three-dimensional spatial co-registration and enabled plaque localization for atherectomy.

What made this case unusual

The tip-detection method, established for intravascular ultrasound, was adapted to OCT-guided atherectomy by using a second curved-tip guidewire to link fluoroscopic orientation with the OCT cross-section.

Diagnostic / clinical pearl

OCT cross-sectional orientation can be co-registered with fluoroscopy using a curved-tip second guidewire, helping localize plaque for directional atherectomy.
