Resumen

MOHANDES, Mohsen et al. Negative angiographic markers in percutaneous coronary intervention of chronic total occlusions. Arch. Cardiol. Méx. [online]. 2018, vol.88, n.2, pp.93-99. ISSN 1665-1731.  https://doi.org/10.1016/j.acmx.2017.01.008.

Objective:

The purpose of this study is to identify negative angiographic predictive variables and the presence of a side branch close to the distal cap of the occlusion in the chronic total occlusion percutaneous coronary intervention outcome.

Methods:

Potential negative angiographic variables were retrospectively evaluated in 156 chronic total occlusions that had undergone a percutaneous coronary intervention. Binary logistic regression with predictive purpose was used to identify a model of variables which, all in all, could successfully predict a negative intervention result.

Results:

Variables independently associated with the procedural failure were multivessel disease (odds ratio = 5.12; 95% confidence interval (CI); 1.94-13.5; P = .001), ambiguous stump presence (odds ratio = 5.08; 95% CI; 2.22-11.63 P < .001), occlusion length ≥20 mm (odds ratio = 3.7; 95% CI; 1.37-9.97 P = .01), and ostial location (odds ratio = 6.53; 95% CI; 1.67-25.63; P = .007). Side branch at distal cap proximity did not remain in the predictive model.

Conclusions:

Multivessel disease, ambiguous stump, a length ≥20 mm, and an ostial location of a chronic total occlusion are independent predictive factors of an unfavourable angioplasty result. A side branch at occlusion distal cap was not associated with the procedural failure.
