“…The true distance in the level of insertion of atrioventricular valves is obtained by substracting the tricuspid-toapex distance from the mitral-to-apex distance with a mean value of 27.25 ± 12 mm in patients with proven Ebstein's anomaly and it is 60 mm as shown in Figure 18 compared to reference group (5.7 ± 2 mm). Kambe and coworkers calculated the distance between both atrioventricular valves directly as a mean value of 21 mm with a range of 14 to 32 mm [36]. A maximum difference in the level of valve insertion of >15 mm in children and >20 mm in adults is discriminated between normal and Ebstein's anomaly [37] [38].…”

Aim: To present the various echocardiographic spectrum of Ebstein's malformation in adolescence and adults. Introduction: Ebstein's anomaly has different anatomic and hemodynamic variables with clinical manifestations of cyanosis, right-sided heart failure and arrhythmias. The leaflet tethering and dysplasia, together with dilatation of the tricuspid valve ring, constitute the anatomic cause of tricuspid regurgitation observed in this condition. Case Reports: The spectrum of leaflet tethering from mild to extreme with varying degrees of tricuspid regurgitation were documented by echocardiography in a 16-year-old cyanotic male with Ebstein's anomaly associated with an atrial septal defect and mild low tricuspid regurgitation (TR), 22-year-old acyanotic male with right-sided heart failure due to severe tricuspid regurgitation and an intact atrial septum, 55-year-old asymptomatic female with moderate high tricuspid regurgitation. The extreme form was described as an "atretic" membrane in a 28-year-old cyanotic male and as a "blanket" of leaflet tissue in a 30-year-old cyanotic male. Conclusion: Ebstein's anomaly has to be suspected clinically in presence of cyanosis with a WPW (Wolf-Parkinson-White) or atrioventricular (AV) block pattern of ECG and its management is complex and must be individualized. RV (right ventricular) exclusion procedures are preferred in advanced cases.

“…The echocardiographic assessment of Ebstein's anomaly focusses on a number of key features. 5,6 The apical four-chamber view demonstrates the displacement of the septal leaflet of the tricuspid valve ( Fig 2); complementary short-axis views of the heart will demonstrate elongation of the anterior and posterior tricuspid valve leaflet. It is important to note that the affected orifice of the tricuspid valve is apically or infundibularly displaced (Fig 3).…”

“…There is tethering of the leaflet of the ventricular septum, and the portion of the right ventricle above the valve annulus is atrialised and thin-walled. The echocardiographic assessment of Ebstein’s anomaly focusses on a number of key features 5 , 6 . The apical four-chamber view demonstrates the displacement of the septal leaflet of the tricuspid valve (Fig 2); complementary short-axis views of the heart will demonstrate elongation of the anterior and posterior tricuspid valve leaflet.…”
