Problems solved by technology

Not all existing related scoring models are suitable for CTO lesions, and their use value before CTO-PCI is also very limited. Therefore, the inventor invented the predictive crown based on the progress of the times, the improvement of surgical technology experience and the continuous updating of instruments. Scoring model for the success rate of interventional therapy for arterial chronic total occlusions

Embodiment

[0025] Scoring model to predict the success rate of interventional therapy for coronary chronic total occlusion lesions, including the following scoring variables: blunt occlusion, 1 point; calcification, 1 point; curvature, 1 point; occlusion length ≥ 20 mm, 1 point; 1 point; collateral circulation, 1 point; previous target vessel CABG history, 1 point; in-stent occlusion, 1 point; orifice occlusion, 1 point; operator variables, -4 points.

[0026] Among them, the judgment criteria of scoring variables are as follows:

[0027] (1) Blunt occlusion: the end of the occlusion does not end in a funnel-shaped, triangular, bead-shaped, etc., but ends in a knife-cut sample, which is a blunt occlusion; If the end does not end in a funnel-shaped, triangular, bead-shaped, etc., but ends in a knife-cut sample, it is blunt occlusion;

[0028] (2) Calcification: There is little difference between entrance and body, mild and severe calcification, that is, if there is calcification in the o...

Abstract

The invention relates to the technical field of coronary artery chronic complete occlusion lesion preoperative evaluation, and discloses a scoring model for predicting the success rate of a coronary artery chronic complete occlusion lesion interventional therapy. The method comprises the following scoring variables: blunt occlusion, 1 point; calcification: 1 point; bending, 1 point; the occlusionlength>=20mm, 1 point; far-end occlusion lesion, 1 point; side branch circulation, 1 point; target blood vessel CABG history, 1 point; occlusion in a stent, 1 point; open occlusion, 1 point, and operator variables, -4 points. The model can be used for evaluating and predicting the complexity of chronic complete occlusion and better predicting the risk of failure of the CTO percutaneous coronary intervention treatment technology, the operator technology and experience are brought into the scoring standard for the first time, scoring variables are increased, and the method has the advantages ofhigh good in applicability and high in prediction capacity.

Description

technical field [0001] The invention relates to the technical field of preoperative assessment of coronary artery chronic total occlusion, in particular to a scoring model for predicting the success rate of interventional therapy for coronary chronic total occlusion. Background technique [0002] Chronic total occlusion (CTO) of coronary arteries refers to coronary artery obstructive lesions with positive TIMI blood flow grade 0 and occlusion time ≥ 3 months. If the TIMI blood flow of the occluded distal vessel is >0 grade, it is still considered as a complete occlusion lesion. Coronary CTO lesions are relatively common, and about 15-25% of coronary heart disease patients undergoing coronary angiography have at least one CTO lesion. Although drug therapy alone can alleviate clinical symptoms in CTO patients, it is not ideal for the improvement of long-term cardiac function and survival rate. [0003] Percutaneous coronary intervention (PCI) for CTO represents the most c...
