Figure legends
FIGURE 1 Chest X-ray showed
cardiomegaly with enlarged right atrial contour (A); The subxiphoid view
of TTE showed the giant RAAA and the PFO (B); The apical four-chamber
view showed large aneurysm, measuring 7.8 × 7.5 cm (C). a = aneurysm;
LA: left atrium; LV: left ventricle; MV: mitral valve; PFO = patent
foramen ovale; RA: right atrium; RAAA = right atrial appendage aneurysm;
RV: right ventricle; TTE = transthoracic echocardiography; TV: tricuspid
valve.
FIGURE 2 Enhanced cardiac computed tomography showed a large dilatation
of the right atrium and atrial appendage. LA: left atrium; LV: left
ventricle; RA: right atrium; RAAA = right atrial appendage aneurysm; RV:
right ventricle.
FIGURE
3
The intraoperative TEE showed the thin wall of
right
atrial appendage aneurysm with a size of 6.1
×
7.9 cm (A); The 4-chamber view showed the right ventricle was compressed
by the atrial appendage aneurysm (B).
LA
= left atrium; LV = left ventricle; MV = mitral valve; RA = right
atrium; RAAA = right atrial appendage aneurysm; RV = right ventricle; TV
= tricuspid valve.
FIGURE 4 The giant RAAA was found
upon opening the pericardium (A); The resected sac of right atrial
appendage aneurysm (B). RAAA = right atrial appendage aneurysm.
FIGURE 5 The
postoperative
TEE showed
a
normal
cardiac
structure and valve function (A); The postoperative TTE showed a
decreased size of right atrium (B); Histopathological sections of the
aneurysm showed thinned myocardium and proliferated blood vessels.
(x100) (C). LA = left atrium; LV = left ventricle; MV = mitral valve; RA
= right atrium; RV = right ventricle; TV = tricuspid valve.
