    Radiofrequency catheter ablation of left-sided accessory pathways via retrograde aortic approach in children
    (ELSEVIER SCIENCE BV, 2016-01-01) Ayabakan, Canan; Sahin, Murat; Celiker, Alpay
    Background: We aimed to analyze the results of retrograde aortic radiofrequency catheter ablation of left-sided accessory pathways in children. Methods: Between January 2010 and September 2014, 25 children who underwent left-sided accessory pathway ablation with a retrograde aortic approach were evaluated retrospectively. Results: The mean age of the patients was 11.09 +/- 3.71 years. Seventeen patients were male (68\%). The mean procedure and fluoroscopy times were 71.54 +/- 21.05 min and 31.42 +/- 19.57 min, respectively. Radiofrequency energy was delivered with 41.38 +/- 15.32 W at 52.38 +/- 5.45 degrees C. Sixteen patients (64\%) presented with manifest preexcitation and, 9 had concealed accessory pathways. The location of accessory pathway was left lateral in 16 patients, posteroseptal in 5, left anterolateral in 2, and left posterolateral and left posterior in the remaining 2. The acute success rate was 96\%. The patients were followed for a mean of 16.68 +/- 18.01 months. There were 2 recurrences. No major complications were observed in the periprocedural period. One patient had groin hematoma, another one had transient severe headache and vomiting. Trivial mitral regurgitation was noted in a patient, which remained the same throughout follow-up. None of the patients developed new aortic regurgitation, pericardial effusion, or thrombi at the site of ablation. Conclusions: The retrograde aortic approach can be safely employed with a high success rate for ablation of left-sided accessory pathways in children. (C) 2016 Japanese Heart Rhythm Society.

    Tracheostomy in Pediatric Intensive Care Unit: When and Where?
    (KOWSAR CORP, 2016-01-01) Ertugrul, Ilker; Kesici, Selman; Bayrakci, Benan; Unal, Omer Faruk
    Background: Tracheostomy was first observed in Egyptian drawings in 3600 BC and performed frequently during the 1800's diphtheria epidemic. Objectives: The aim of this study was to elucidate the indications, complications, mortality rate, and the effect of pediatric tracheostomy on length of PICU or hospital stay. Materials and Methods: Demographic characteristics, diagnosis at admission, duration of ventilation of 152 patients were analyzed retrospectively. Results: The most common tracheostomy indication was prolonged intubation. The mean duration of mechanical ventilation before tracheostomy was 23.8 days. Forty five percent of the tracheostomy procedures were performed at bedside. Neither the place nor the age had any effect on the development of complications (P = 0.701, P = 0.622). The procedure enabled 62\% of the patients to be discharged from hospital. Conclusions: Tracheostomy facilitates discharge and weaning of mechanical ventilation. Although the timing of tracheostomy has to be determined for each individual patient, three weeks of ventilation seems to be a suitable period for tracheostomy. Tracheostomy can be performed at bedside safely but patient selection should be made carefully.
