Background: Rotablation is one of the strategic options for technical success of percutaneous coronary intervention (PCI) in the severely calcified lesion. However, long-term clinical prognosis after PCI with rotablation has not been fully discussed in the drug-eluting stent (DES) era.
Methods: This study included 404 consecutive patients who underwent PCI with rotablation between 2004 and 2013. Enrolled patients were retrospectively divided into 2 groups due to the incidence of major adverse cardiac event (MACE) at 2 years after PCI. MACE included cardiovascular death, target lesion revascularization, non-fatal myocardial infarction and stent thrombosis.
Results: Overall MACE was observed in 108 patients (27%) at 2 years. Patients with MACE were significantly younger, and frequently had diabetes, current smoking, chronic kidney disease (CKD) and lower left ventricular ejection fraction (LVEF). As for angiographic parameters, lower rate of left anterior descending (LAD) lesion was targeted in patients with MACE. Logistic regression analysis revealed that CKD, low age, low LVEF and Non-LAD lesion were independent predictors for 2-year MACE (Figure). Positive correlation between 2-year MACE and score of those predictors was observed (p<0.001, Figure). Score ≥2 had 67.6% sensitivity and 74.0% specificity for predicting 2-year MACE, and PPV was 67.6%.
Conclusions: In the DES era, specific clinical and angiographic parameters at baseline may predict long-term prognosis after rotablation.
