New score to predict complications during chronic total occlusion PCI

medwireNews: Researchers have developed a new score to predict complications during chronic total occlusion (CTO) percutaneous coronary intervention (PCI).

Their score – developed by analysing data in the PROGRESS CTO registry from 1569 patients who underwent CTO PCI – takes into account age, CTO length and use of the retrograde approach.

“To the best of our knowledge, this is the first score specifically designed to predict complications during CTO PCI and may be of great value for procedural planning and discussion with the patient”, write study authors Emmanouil Brilakis (Dallas VA Medical Center, Texas, USA) and colleagues.

As reported in the Journal of the American Heart Association, score values of 0–2, 3–4 and >5 were able to identify patients at low, medium and high risk, respectively, for periprocedural complications in both derivation and validation cohorts, with an accuracy of around 75%.

The authors caution that the PROGRESS CTO score has not yet been validated in an external independent cohort, but note that “[the] use of a simple, validated score specific for complications (in addition to scores predicting success and efficiency) can significantly aid physician and patient decision making”.
