    Complications of cardiac catheterization in pediatric patients: a single center experience
    (Turkish J Pediatrics, 2012) Yilmazer, Murat Muhtar; Ustyol, Ala; Guven, Baris; Oner, Taliha; Demirpence, Savas; Doksoz, Onder; Mese, Timur
    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 <1 year of age by univariate analysis. The risks of pediatric cardiac catheterization continue to decline. The complication rates associated with interventional catheterization were significantly higher than with diagnostic catheterization in this study. Younger age, particularly <1 year of age, is the strongest predictor of development of any complication.

    Improvement in cardiac structure and functions early after transcatheter closure of secundum atrial septal defect in children and adolescents
    (Turkish J Pediatrics, 2013) Yilmazer, Murat Muhtar; Guven, Baris; Vupa-Cilengiroglu, Ozgul; Oner, Taliha; Demirpence, Savas; Mese, Timur; Tavli, Vedide
    We sought to assess the effects of transcatheter closure of atrial septal defect (ASD) on right and left ventricular form and functions, as well as atrial volumes and pulmonary venous flows. We enrolled 25 patients (mean age: 9.02) prospectively who underwent successful transcatheter closure of secundum ASD. We performed transthoracic echocardiography, including two-dimensional, pulsed wave Doppler, M-mode echocardiography, and tissue Doppler imaging before the procedure and 1 day, 1 month, 3 months and 6 months after the procedure. Serum brain natriuretic peptide (BNP) levels were measured prior to the procedure, and 1 day, 1 month, and 3 months thereafter. Mitral inflow early diastolic wave increased significantly, while isovolumetric relaxation time and deceleration time did not change during the follow-up. The E/E'was also increased significantly during follow-up. After the closure, right ventricular size and right atrial volume reduced, while left ventricular size increased significantly. There was a statistically significant improvement in left and right ventricular Tei indices. Pulmonary vein systolic velocity and the ratio of systolic to diastolic wave decreased, while atrial reversal wave (ARW) velocity increased immediately after the procedure. Although the concentration of BNP was increased on the first day after the procedure, its levels reduced and had reached the pre-procedure values at 1 month of follow-up. In the study, a significant improvement in the right and left ventricular functions was detected after transcatheter closure of secundum ASD in the short-term follow-up. In addition, we found a significant reduction in right heart sizes with corresponding global functional improvement in the right ventricle after the procedure.
