Figure legends :
Figure 1 : The trans-oesophageal mid-oesophageal four -chamber
echocardiography showing a thick-walled multi-septate honeycombed cyst
(6.9cm Χ 5.6 cm) ,completely occupying interventricular septum (RV
: right ventricle, LV: left ventricle , IVS: inter ventricular septum )
Figure 2 : The trans-oesophageal echocardiography showing the
intra-cardiac structural involvement with the cyst : mid-oesophageal
four chamber view showing septal tricuspid leaflet adherent to the cyst
(A); the mid-oesophageal aortic valve long-axis view showing the
protrusion of the cyst into the left ventricle outflow tract without any
turbulence on colour doppler(B)(RA: right atria, RV: right
ventricle, LA: left atria, LV: left ventricle, IVS : inter-ventricular
septum, ATL : anterior tricuspid leaflet , STL: septal tricuspid
leaflet, AoV: aortic valve , LVOT: left ventricle outflow tract )
Figure 3 : The trans-oesophageal mid-oesophageal right
ventricle focussed view showed no tricuspid regurgitation on colour
doppler suggestive of insignificant leaflet adhesion to cyst
membrane(RA: right atria, RV: right ventricle, LA : left atria,
IVS: inter ventricular septum )
Figure 4 : The trans-oesophageal right ventricle focused view
acquired after cyst excision showed an intact interventricular septum
and no tricuspid regurgitation (RA: right atria, RV: right
ventricle, LA: left atria , IVS: interventricular septum, TR: tricuspid
regurgitation )
