چکیده انگلیسی


• Rotablation is proposed during PCI in complex and severely calcified lesions.
• Per-lesion calcium score on MDCT is a simple marker of regional calcified plaque condition.
• High per-lesion calcium score was an independent predictor for the addition of Rotablation during PCI.

BackgroundRotational atherectomy (rotablation) has been proposed as a potentially superior strategy for percutaneous coronary intervention (PCI) in complex and severely calcified lesions.ObjectivesWe hypothesized that a per-lesion coronary artery calcium score determined by multidetector computed tomography (MDCT) would be useful for predicting the requriement for rotablation during PCI.MethodsMDCT was performed in patients with stable angina pectoris who were scheduled for first PCI. In 116 consecutive subjects (168 target lesions) with successful PCI, MDCT and quantitative coronary angiography (QCA) data were retrospectively evaluated regarding their ability to predict rotablation.ResultsPCI without rotablation was performed in 105 patients (154 lesions), and rotablation was added in 11 patients (14 lesions). Patients with rotablation had significantly higher SYNTAX scores (p = 0.007) and total calcium scores (p < 0.001) than those without rotablation. Per-lesion, a lesion length ≥20 mm and diameter stenosis ≥74% on QCA as well as a per-lesion calcium score ≥453 and calcification arc ≥270 in MDCT predicted rotablation. After adjustment for potential confounding variables, a high per-lesion calcium score was an independent predictor of rotablation (odds ratio 31.3, 95% confidence interval 2.8-345, p = 0.005, sensitivity 93% and specificity 88%).ConclusionThe extent of target lesion calcification in MDCT, a simple marker of calcified plaque, is useful for predicting the need for rotablation during PCI.
