Complications of cardiac catheterization in pediatric patients: a single center experience.

Abstract

We analyzed 519 catheterization procedures performed over a period of two years retrospectively. Several risk factors related to the patient or catheterization were analyzed. The incidence of complications was 6.2%. The most common major and minor complications were arterial thrombosis that required intervention and transient arrhythmias, respectively. The incidence of complications during interventional studies was higher (9.7%) when compared to that in diagnostic procedures (5.4%). The independent risk of any complication was greatest up to 1 year of age (p = 0.02). The risks of a major complication (p = 0.003) and development of arterial thrombosis (p = 0.02) were significantly greater in patients
