Optimal threshold of postintervention minimum stent area to predict in-stent restenosis in small coronary arteries: An optical coherence tomography analysis

ABSTRACT


OBJECTIVES - The aim of this study was to determine the best threshold of postintervention minimum stent area (MSA) assessed by optical coherence tomography (OCT) to predict long-term in-stent restenosis (ISR) for 2.5 mm-diameter everolimus-eluting stents (EES).

 

BACKGROUND - Percutaneous coronary intervention (PCI) for small coronary arteries remains challenging. Stent underexpansion is a strong predictor of late ISR.

 

METHODS - We performed a retrospective analysis of 69 lesions in 69 patients undergoing PCI with 2.5 mm-diameter stents using OCT for the assessment of postintervention MSA and subsequent 9-month angiographic follow-up.

 

RESULTS - The rates of angiographic ISR and target lesion revascularization were 7.2% and 1.4%. The postintervention OCT-MSA of EES < 3.5 mm(2) for predicting ISR yielded a sensitivity of 80%, specificity of 71%, positive predictive value of 18%, and negative predictive value of 98%. There was a marginally significant trend between increasing MSA quartiles and decreasing ISR rate (P for trend = 0.07).

 

CONCLUSIONS - Postintervention OCT-MSA of 3.5 mm(2) best predicted 9-month ISR following PCI with 2.5-mm-diameter EES. Further large, prospective, observational studies are warranted that validate this result.
