Figure 12: Leaflet anomalies resulting in coaptation defects. In (a), there is a cleft in the anterior leaflet (arrow); when the valve closes there is a coaptation defect where the cleft in anterior leaflet contacts the posterior leaflet (b,c black arrow); (b) right atrial (RA) view, (c) right ventricular (RV) view. This patient had mild to moderate insufficiency through the defect caused by the cleft (b, black arrow) and a trivial insufficiency jet through a small coaptation defect at the anteroseptal commissure (b, white arrow). (d) demonstrates a quadraleaflet tricuspid valve (TV). In systole, there is a large diamond-shaped coaptation defect in the central aspect of the valve between the four leaflets (e,f white arrow); (e) right atrial (RA) view, (f) right ventricular (RV) view. The patient had moderate to severe insufficiency through this coaptation defect. A: Anterior leaflet, P: Posterior leaflet, S: Septal leaflet, AL: Anterolateral leaflet
