The yield of 24-hour ambulatory electrocardiography in the assessment of symptomatic school-age children.

Introduction: Lightheadedness, syncope, dyspnea, chest pain, palpitation, loss of consciousness (LOC) or malaise are a frequent reason for consultation in school-age children (SAC). The yield of holter monitoring (HM) in the investigation of these symptoms in SAC is still controversial given the scarce studies.

Aim: To determine the prevalence of baseline ECG abnormalities and those detected in HM in SAC, and to assess the predictive factors of abnormal HM test.

[Long-term repaired tetralogy of Fallot : Echocardiographic parameters in correlation with cardiac MRI].

Introduction: Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease. After surgical repair, the excellent survival rate has led to long-term complications dominated by pulmonary regurgitation (PR). Our study aimed to identify echocardiographic criteria for assessment of right ventricular (RV) function and quantification of PR correlated with cardiac MRI indices.
