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.

Assessment of ventricular function after total cavo-pulmonary derivation in adult patients: Interest of global longitudinal strain.

Ventricular dysfunction is the most frequent complication in adult patients post-Fontan completion. Through this work, we aim to evaluate ventricular systolic function by conventional echographic parameters and by global longitudinal strain (GLS) to determine the prediction of early ventricular systolic dysfunction. This is a prospective monocentric study enrolling 15 clinically stable adult Fontan patients with preserved ejection fraction (EF).

[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.

Molecular autopsy and clinical family screening in a case of sudden cardiac death reveals ACTN2 mutation related to hypertrophic/dilated cardiomyopathy and a novel LZTR1 variant associated with Noonan syndrome.

Background: Genetic cardiac diseases are the main trigger of sudden cardiac death (SCD) in young adults. Hypertrophic cardiomyopathy (HCM) is the most prevalent cardiomyopathy and accounts for 0.5 to 1% of SCD cases per year.

Electocardiographic features in Ebstein's disease.

Introduction: Ebstein's disease (ED) is a rare and heterogeneous congenital heart disease affecting the tricuspid valve and the right ventricle. Few studies have analyzed the electrocardiographic features of this disease.

Aim: To describe the electrocardiographic features observed in Ebstein's disease.

Particularities of neonatal isthmic aortic coarctation (A Tunisian study).

Methods: This is a retrospective study including 47 patients with isthmic coarctation (CoA) diagnosed in ante et postnatal périod, hospitalized in pediatric cardiology departement of la Rabta Hospital-Tunisia during the period from 2000 to 2017.

Results: They were 36 girls and 11 boys with an average age of 14 days. The diagnosis of CoA was suspected during the anténatalperiod in eight cases.

[Late reinterventions after repair of common arterial trunk].

Background: The common arterial trunk is a heart disease in witch a unique arterial trunk, with a unique ventriculo-arterial valve, exits from the ventricular mass and supply directly the coronary, the aortic and also the pulmonary arterial circulations. Its anatomic repair is now possible but necessitates the use of conduit in pulmonary position.

Aim: To evaluate the incidence and the causes of late reinterventions after repair of common arterial trunk.

[Atrial flutter in neonates and infants: diagnosis and treatment].

Between 1995 and 2002, 5 patients with a mean age of 32 years have been treated for atrial flutter in the Department of Paediatric Cardiology at Hospital La Rabta. In all cases, diagnosis was established on surface electrocardiogram (12 leads. All patients had a normal heart.
