Intra-aortic vs. Intra-erotic

Well, the title tells it all; so be careful with terminology.

Intra-aortic vs. Intra-erotic
A swap of one letter
And timing dicrotic,
Both involving position
Of a foreign body,
Regarding cardiac output
Or your favorite hottie.

Key factors, stroke work
Performance and action,
Attention is paramount
There should be no distraction,
You will achieve the best results
If  you control your design,
Those intra-aortic-erotics
Then, everything will be fine.
