Imaging findings
Contrast-enhanced CT demonstrates a "spade-shaped" left ventricular cavity, characterized by a normal-appearing base and marked apical myocardial hypertrophy. A large aneurysm with preserved trabeculations is present at the apex of the left ventricle, and coronary CT angiography shows completely normal coronary arteries.
Key takeaways
Apical hypertrophic cardiomyopathy can lead to the development of a large apical aneurysm due to high systolic pressures generated within the ventricular apex from mid-cavity obstruction. It is important to distinguish this from post-infarction aneurysms; the presence of normal coronary arteries and preserved apical trabeculations can help confirm this diagnosis.
