The anterior leaflet is not displaced and hence is quite large and sail like. Closure of the large anterior tricuspid leaflet produces the <span style=\"color: #0000ff;\">&#8216;sail sound&#8217;<\/span> characteristic of Ebstein&#8217;s anomaly. The distal displacement of the tricuspid valve causes atrialization of a portion of the right ventricle. This region can be identified during cardiac catheterization as showing ventricular electrogram, but an atrial pressure tracing. This finding is sought by <strong><em>Zucker catheter<\/em><\/strong> which has a lumen for pressure recording as well as an electrode for electrogram recording. The finding is called<strong> Hernandez sign&nbsp;<\/strong>[1,2].<\/p>\n<p><span style=\"color: #0000ff;\">Ebstein&#8217;s anomaly has been associated with maternal intake of lithium during pregnancy.<\/span> Right sided accessory pathways are seen in Ebstein&#8217;s anomaly of the tricuspid valve. A similar anomaly of the left sided AV valve has been associated with congenitally corrected transposition of the great arteries. The tricuspid valve in Ebstein&#8217;s anomaly can have tricuspid stenosis, regurgitation or a combination of both together. Associated atrial septal defect can cause a right to left shunt and cyanosis.<\/p>\n<p>Clinically they have multiple heart sounds due to split first and second heart sound. A superficial scratchy tricuspid murmur is also often heard. ECG shows <a href=\"https:\/\/johnsonfrancis.org\/professional\/polyphasic-or-splintered-qrs-in-ebsteins-anomaly-of-tricuspid-valve-2\/\">splintered polyphasic QRS complexes<\/a>, tall P waves (<em><strong>Himalayan&nbsp;P waves<\/strong><\/em>) and sometimes features of preexcitation and atrioventricular reentrant tachycardia. X-ray chest shows the huge right atrial enlargement, which can be confirmed by echocardiography. M-mode echo shows the delay between the mitral and tricuspid valve closures. Both valves are imaged in the same parasternal view in Ebstein&#8217;s anomaly. The distal displacement of the septal tricuspid leaflet is the characteristic echocardiographic finding in Ebstein&#8217;s anomaly.<\/p>\n<p>Surgical repair is by <a href=\"_wp_link_placeholder\" data-wplink-edit=\"true\">Cone procedure<\/a> which constructs a funnel like valve using the native valve leaflets. This avoids the problems associated with artificial valves including bioprosthetic valves, especially in children.<\/p>\n<p><strong><span style=\"color: #0000ff;\">References<\/span><\/strong><\/p>\n<ol>\n<li>Hernandez FA, Rochkind R, Cooper HR. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/13508538\/\">The intracavitary electrocardiogram in the diagnosis of Ebstein&#8217;s anomaly<\/a>.&nbsp;Am J Cardiol. 1958 Feb;1(2):181-90.<\/li>\n<li>Watson H.
