Aim: The study was performed to assess the prevalence of Chiari's Network (CN) in a pediatric outpatient department population by using transthoracic echocardiography (TTE) and to determine its association with other cardiac anomalies. Material and Method: 2232 children who underwent cardiac examination and TTE at the pediatric cardiology outpatient department of our institution between April 2013 and April 2014 were included in the study. Routine M-mode, 2-D, and Doppler studies were applied. All co-existent lesions were recorded. Ratio between heights of early and late diastolic flow velocity peaks (E/A) were < 1 in tricuspid and mitral valves considered as possible right and left diastolic dysfunctions respectively.(Bu cumle eklendi.) Results: Of 2232 children, CN was detected in 76 patients (3.41%) and found most frequently during the first month. Atrial septal defect and patent foramen ovale (ASD/PFO) was the most common congenital defect seen with CN (55.3%). Ten children (13.2%) had peripheral pulmonary stenosis (PPS) and seven (9.21%) showed atrial septal aneurism (ASA) associated with CN. Of patients with CN, a total of 11 patients (14.5%), 10 of them 1-8 days old and 1 of them 17 days old, had E/A< 1 in tricuspid valve. Three (3.9%) patients 1-12 days old demonstrated E/A< 1 in tricuspid and mitral valves. Twenty-nine of the studied patients (11%) demonstrated E/A< 1 in tricuspid valve (90% 1-30 days old). Of the total 2232 patients, 267 individuals (8.4%) showed ASA whereas there were only 7 cases (9.6%) of CN patients. Discussion: CN is an uncommon and incidental finding that should be recognized appropriately. This may not be always a normal variant. Proper documentation of CN is critical regarding possible future complications.
