[Complications of cardiac catheterisation in congenital heart disease. 30 years of experience. A new risk-adjusted score].

OBJETIVE: To present a risk-ajusted score of complications during cardias catheterization in congenital heart disease.

DESIGN

observational, analitic, ambispective of 3.504 cases. The data analyzed included age, heart disease, type of procedure, major and minor complications.

METHODS

3.504 procedures performed between october 1987 and may 2019. The variables were age, heart disease, procedere and clinical stege. Each patients was categorized as low risk 5 to 7 points, moderate risk 8 to 11 points and higt risk 12 to 22 points. The score was validated using the Hosmer-Lemeshow test and the ROC curve (Receiver Operating Characteristic).

RESULTS

complications 177 (5%) 66 major (1.9%) and 111 minor (3.1%). Mortality was 0.4% (15 patients). The low-risk group (n = 825) had 1.5% complications; moderate risk (n = 2,221) 4.9%; high risk (n: 458) 12% (p < 0.001). The analysis of the retrospective data (n = 2953) was validated with prospective (n = 551) using the Hosmer-Lemeshow test, showed that the predicted values are similar to those observed.

CONCLUSIONS

Complications continue to occur despite the evolution of the technique. The score was useful for stratifying patients and knowing the probability of complication before the procedere.
