title: A lesion marker to facilitate placement of the Simpson's atherocath device during directional atherectomy of left anterior descending coronary artery stenoses.
abstract: Placement of the directional coronary atherectomy cutter requires frequent angiographic contrast injections to aid in the precise location of the device in relation to the target stenosis. A method is described to enable rapid positioning of this device across stenotic lesions occurring in the left anterior descending coronary artery, with the use of a simple lesion marker. Two short lines demarcating the limits of the stenotic lesion are drawn onto a transparent one-sided adhesive plastic sheet that has been pasted beforehand onto the active monitor screen. Using this reference marker, the atherectomy device can be reliably positioned across the stenotic lesion.
