An 85-year-old woman with known coronary artery disease (prior stents in the left anterior descending [LAD] and left circumflex [LCX] coronary arteries placed in 1996), presented with chest pain. A 12-lead electrocardiogram (ECG) revealed 1 mm ST-segment elevation in V4-V6. Bedside two-dimensional echocardiogram demonstrated LAD territory wall-motion abnormalities and the patient was taken emergently to the catheterization laboratory.
Cardiac catheterization revealed multivessel coronary artery disease with severe calcific ostial LAD and LCX disease. An intra-aortic balloon pump was inserted and the symptoms and ECG changes resolved. The patient later became symptomatic in the intensive care unit, with dynamic ECG changes (Figure 1A), but refused surgical revascularization. A high-risk percutaneous coronary intervention was then planned after discussion with the multidisciplinary team.
A percutaneous left ventricular assist device was inserted for hemodynamic support. We devised a novel “GuideLiner-sleeve” technique to perform orbital atherectomy of the ostial LAD and LCX (Figures 1B-1G), protecting each vessel with a coronary guidewire while performing atherectomy of the other vessel. We used two guiding catheters from bilateral radial arteries to wire both the LAD and LCX. We advanced a GuideLiner catheter (Vascular Solutions) as a sleeve over the guidewire in the LAD and performed orbital atherectomy of the LCX ostial lesion, then reversed the configuration to perform atherectomy of the LAD while protecting the LCX. Following orbital atherectomy, left main bifurcation stenting was successfully completed using the double-kissing crush technique.1 The patient was subsequently discharged home in stable condition and remains well at follow-up.
Our novel GuideLiner-sleeve technique enabled use of atherectomy in calcific ostial lesions of the LAD and LCX. Due to the differential sanding effect, the GuideLiner effectively protects the second guidewire, allowing safe access to the second major epicardial vessel throughout the procedure.
