Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced towards the apex of the right ventricle of the heart.
Symptoms: Mild forms of Ebstein's anomaly may not cause symptoms until later in adulthood. If signs and symptoms are present, they may include: Shortness of breath, especially with exertion . Fatigue . Heart palpitations or abnormal heart rhythms (arrhythmias) .A bluish discoloration of the lips and skin caused by low oxygen.
Diagnosis: To diagnose the conditions,doctor will examine the child check their heartbeat and listen to the their heart. In children with this anomaly, doctors can often hear a heart murmur.It may include several tests such as: Chest X-rays, echocardiogram, electrocardiogram or MRI (magnetic resonance imaging).
Treatment: a. Antibiotic prophylaxis for infective endocarditis b. Medical therapy for heart failure - Angiotensin-converting enzyme (ACE) inhibitors, diuretics, and digoxin c. Arrhythmia treatment - Medical treatments such as anti-arrhythmic drugs or radiofrequency ablation of the accessory pathways 1. Curative therapy of SVT with radiofrequency ablation is currently the treatment of choice. 2. The success rate is lower than that in patients without significant structural heart disease. 3. Factors associated with lower likelihood of success include the following: Accessory pathways located along the atrialized right ventricle. Multiple accessory pathways. Complex geometry of the pathways. Abnormal morphology of the endocardial action potentials in this region.
Epidemology: Total prevalence of individual lesions, and distribution of sentinel cardiac anomalies, in the Italian study and compare them with EUROCAT. Isolated ventricular septal defect is the most common lesion (39%); followed by atrial septal defect (7.5%); pulmonary valvar stenosis (7.3%); atrioventricular septal defects (5.4%); patency of the arterial duct (3.8%); complete transposition (3.7%); tetralogy of Fallot (3.3%); aortic coarctation (2.4%); aortic valvar stenosis (2.2%); and left heart hypoplasia (1.8%).
