The evaluation of cases with double-inlet left ventricle-ventriculoarterial discordance

Background: This study aims to evaluate the cases of functional univentricle with the diagnosis of double-inlet left ventricle-ventriculoarterial discordance

Evaluation of autonomic nervous system functions in frame of heart rate variability in children with inflammatory bowel disease in remission

Heart Rate Variability (HRV) is one of the reliable and noninvasive parameters to evaluate autonomic control of the cardiovascular system in patients. The aim of our study was to assess autonomic function in pediatric patients with inflammatory bowel disease (IBD) in remission using Power Spectral Analysis of HRV. Autonomic cardiovascular function was evaluated by time and frequency-domain indexes of spontaneous heart rate in 36 IBD children patients in remission phase and 36 sex and age matched healthy controls. Twenty children with Ulcerative Colitis (UC) and 16 patients with Crohn's disease (CD) were diagnosed according to their history, physical and laboratory examination, endoscopic, histopathological and radiological findings of upper and lower gastrointestinal system. Significant decrease was observed at HRV parameters in IBD patients when compared with control group. These differences was found in some of time domain parameters (NNmean, SDNNtotal, SDNNday) and frequency domain parameters (TP, LF, VLF) (p<0.05). Also, there was a significant higher minimum heart rate ratio (p<0.04) in patients in comparison to the control group. In the IBD group, there was a relative tendency for parasympathetic suppression and sympathetic predominance which reflects an autonomic dysfunction. This imbalance has a circadian rhythm and it is more obvious during the day. These observations may suggest a previously unrecognized role of chronic inflammation for autonomic modulation in IBD

Impact of Coronary Artery Anatomy in Arterial Switch Procedure on Early Mortality and Morbidity

ObjectiveArterial switch operation has become the treatment of choice for neonates with transposition of the great arteries. The most important step of the procedure is transferring the coronary arteries to the neoaorta successfully. This study shows the impact of coronary anatomy on early mortality and morbidity after arterial switch operation

Heart rate variability improvement in children using transcatheter atrial septal defect closure

Objective: We evaluated autonomic behavior by examining heart rate variability (HRV) in the time domain and frequency domain in pediatric patients who underwent transcatheter closure of atrial septal defect (ASD)
