A 60-year-old woman presented with chest pain
and dyspnea, and her medical history included an
anterior myocardial infarction eight years earlier.
An electrocardiogram revealed ST-segment elevation
with associated Q-waves in the V1, V2, II, III
and aVF leads. The transthoracic echocardiography
showed a hyper-reflective calcified apical aneurysm.
The patient’s end diastolic volume was 186 mL, and
she had an ejection fraction of 38%. Subsequent
coronary angiography revealed a total occlusion
of the left anterior descending artery and the midportion
of the right coronary artery as well as
critical stenosis of the circumflex coronary artery.
A oval-shaped calcified structure that resembled
a calcified apical left ventricular aneurysm was
observed during the left main artery (Figure
1a)
and right coronary artery injections (Figure
1b).
The patient then underwent an uneventful quadruple
myocardial revascularization operation that included
the resection of the calcified aneurysm (Figure
2a)
and the reconstruction of the left ventricular wall via
endoventricular patch plasty, which was previously
described by Cooley.[

identified as a massive, calcified, semi-oval sphere
measuring 4.5x4 cm (Figure
2b).

Left ventricular aneurysms occur as a serious
complication of transmural myocardial infarction, but
massive calcified ventricular aneurysms are seen much
less frequently.[2-4] However, as our case points out, the
possibility of these types of aneurysms should not be
overlooked.
