Evaluation of the frequency of complications and affecting factors in children undergoing cardiac catheterisation

Abstract Background: This study aims to identify the factors affecting the development of complications and to present the necessary data to the literature in order to reduce the frequency of complications as a result of some measures that can be taken against them. Methods: This retrospective study included 609 patients between the ages of 0 and 18 who underwent cardiac catheterisation between 2012 and 2020 by our Department of Paediatric Cardiology. The patient’s demographic data, cardiac catheterisation-related data, laboratory results, and all data in the post-procedure records are scanned and evaluated. Results: Of the patients aged between 0 and 216 months (mean 67.1 ± 55.8 months), 371 were female (60.9%). Interventional catheterisation was performed in 419 (68.4%) of the patients, and diagnostic catheterisation was performed in 193 (31.6%). Complications were detected in 39 patients (6.4%). The most frequent complications were vascular complications in 16 patients (41%), bleeding in 5 patients (12.8%), anaemia in 4 patients (10.3%), and arrhythmia in 3 patients (7.7%). Mortality occurred in 2 patients (0.3%). Risk factors for the development of complications were determined as
