    Objective: To evaluate the association between the degree of pulmonary arterial hypertension (PAH) and the level of malnutrition in children with acyanotic congenital heart diseases and left-to-right shunt, and especially to evaluate the development rates of malnutrition in patients with borderline PAH. Methods: The study was performed with data of 327 patients with acyanotic congenital heart diseases and left-to-right shunt and underwent cardiac catheterization between January 2001-February 2011. The design of the study was retrospective and observational. All patients were evaluated with anthropometric measurements, echocardiography and cardiac catheterization. They were classified according to the mean pulmonary artery pressure and level of malnutrition. Chi-square, ANOVA and Kruskal-Wallis tests were used for statistical analysis. Normally and abnormally distributed data were analyzed with Pearson and Spearman correlation tests respectively. Results: Malnutrition was detected in 94.8% of patients with PAH and 17.2% of no PAN patients according to Gomez classification (p<0.001). In addition, malnutrition was detected in 23.5% (16/68) of borderline PAN group. A negative association was detected between mean pulmonary arterial pressure and body weight for age (Gomez) and z scores of weight (p<0.001 for all). Z scores of weight and height were significantly decreased in patients with PAH in contrast to no PAH group (p<0.001, p<0.01 respectively). There was no statistical difference between no PAH and borderline PAH groups according to Gomez classification and relative body weight formula, however z scores of weight in borderline PAN group were decreased compared with no PAH group (p<0.001). Conclusion: A positive association was detected between the degrees of PAH and level of malnutrition in children with a cyanotic congenital heart diseases with left-to-right shunt. Borderline PAH may be a predisposing factor for malnutrition and further studies are needed for this subject. (Anadolu Kardiyol Derg 2012; 12: 150-9)

    Dispersion Durations of P-wave and QT Interval in Children With Congenital Heart Disease and Pulmonary Arterial Hypertension
    (SPRINGER, 2013) Sap, Fatih; Karataş, Zehra; Altın, Hakan; Alp, Hayrullah; Oran, Bülent; Baysal, Tamer; Karaarslan, Sevim
    This study aimed to investigate homogeneity disorders of ventricular repolarization and atrial conduction via QT dispersion and P-wave dispersion in children with congenital heart disease (CHD) and pulmonary arterial hypertension (PAH). Three groups of 20 each were generated and involved in this study. The first group included 20 children with both CHD and PAH. The second group consisted of 20 children with CHD but no PAH, and the third group was composed of 20 age- and sex-matched healthy children. Electrocardiographic records were used to determine P-wave, QT, and corrected QT (QTc) dispersions. The pulmonary hypertension group compared with the group having no pulmonary hypertension and the control group showed a significantly longer P-wave dispersion duration (39.10 +/- A 9.54 vs. 26.30 +/- A 4.99 ms, p < 0.001; and 24.80 +/- A 6.94 ms, p < 0.001, respectively) and QT dispersion duration (52.80 +/- A 15.11 vs. 37.60 +/- A 6.00 ms, p < 0.001; and 35.00 +/- A 7.77 ms, p < 0.001, respectively). In addition, the durations of maximum QTc and QTc dispersion were significantly longer in pulmonary hypertension group than in the other two groups. The risk of atrial and ventricular arrhythmia was found to be increased in the patients with both CHD and PAH. Physicians should pay close attention to possible atrial and ventricular arrhythmias during the treatment and follow-up evaluation of these patients.
