A banana shaped left ventricle on imaging is characteristically seen in which condition?
Show Hint
Asymmetric septal thickening curves the cavity into a banana shape.
Updated On: Jun 24, 2026
- HOCM (hypertrophic obstructive cardiomyopathy)
- DCM (dilated cardiomyopathy)
- RCM (restrictive cardiomyopathy)
- Takotsubo cardiomyopathy
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Cavity morphology is a recognised imaging signpost. In hypertrophic cardiomyopathy the thickened, asymmetric septum squeezes the chamber into a slender curved silhouette resembling a banana, so option a is the right pick.
Step 2: A round, ball-like (spherical) chamber instead points to dilated cardiomyopathy where the muscle thins and the heart balloons out evenly.
Step 3: Takotsubo or stress cardiomyopathy produces transient apical ballooning that mimics an octopus pot, and apical hypertrophic cardiomyopathy carves out a spade-shaped cavity on ventriculography.
Step 4: After a myocardial infarction the wall may bulge or form an aneurysm, distorting the ventricle, but this is not banana shaped. Hence hypertrophic cardiomyopathy remains the single best answer.
\[\boxed{\text{HOCM}}\]
