A Clinical and Angiographic Scoring System to Predict the Probability of Successful First-Attempt Percutaneous Coronary Intervention in Patients With Total Chronic Coronary Occlusion

Abstract

This clinical and angiographic score predicted the final CTO-PCI procedural outcome of our study population.

Intravascular ultrasound in percutanous coronary intervention for chronic total occlusions: predictors of use, indications and in-hospital outcome

“…The absence of a well-defined (ambigous) stump is a major limitation for CTO recanalization [16,17]. The major indication of IVUS in our study was antegrade proximal cap puncture.…”

Chronic Total Occlusion Percutaneous Coronary Intervention: Evidence and Controversies

“…Several scoring systems have been developed to determine the likelihood of CTO PCI technical success and the potential difficulty of the procedure (measured as time required to cross the occlusion), such as the CL Clinical and lesion‐related) score,34 Ellis score,35 Japan‐chronic total occlusion score (J‐CTO),36 Ostial, Rentrop grade, Age score (ORA),37 PROGRESS‐CTO score,38 and RECHARGE score39 (Table 3). These scores combine various clinical and angiographic characteristics and can provide a quantitative assessment of the likelihood of success and the difficulty of the case, as long as they are applied in similar settings as the ones that they were developed on.…”

Predicting endovascular intervention outcomes in patients with chronic total occlusion of coronary artery. Can we forecast the result?

“…[24] разработали шкалу CL, которая включает как клинический, так и ангиографический предикторы: предыдущее аортокоронарное шунтирование (+1,5), предшествующий инфаркт миокарда (+1), выражен-ный кальциноз (+2), длина ХОКА >20 мм (+1,5), хро-ническую окклюзию коронарных артерий не передней нисходящей артерии (+1), плоскую форму культи (+1). Шкала CL направлена на прогнозирование успеха про-цедуры (технический успех процедуры при отсутс-твии значимых осложнений на госпитальном этапе).…”
