Well, not exactly rocket science, but last weekend I admitted a patient who I found incidentally had critical aortic stenosis (a life threatening narrowing of the aortic valve; that’s not what they had come in for (their gallbladder) but I actually listened to her heart with my stethoscope, and heard the harsh murmur and got an echocardiogram.

I tried to explain how critically tight the valve was and that we would need to replace the valve (traditionally that required open heart surgery [where we “kill you” put you on bypass pump and then “unkill you”, but now we can do it via “TAVR” which is a cool origami like valve that gets deployed via a catheter and pops into shape while the patient is awake - day procedure). But the patient and family couldn’t understand what 0.3 square cm of area meant. So, I thought, hey, I have a laser. And so quickly made a CAD file (since OnShape has a scripting language) of every size from 03.0 down to 0.4 square cm (essentially a pasta sizer).

This totally cracked me up because you lead with that and then immediately go into heart /vascular that is orders of magnitude more complex.


#3

Too funny and I actually understand! Great use of an alternate resource. It’s all about communication…


#4

I’m enjoying the medical term “unkill.”


#5

Rocket science is easier… trust me :slight_smile:

Your medical projects are some of the most interesting ones on the forum. Your stakes are much higher than what I make, that’s for sure. Nicely done.


#8

Like this kind of origami heart?


#9

Very interesting!! Did it work (that is did they understand the concept better?) :mask:

I was “lucky” for my bypass they used the DaVinci machine (robotic) so no “unkilling” required :grinning:

(Actually yesterday was my surgery anniversary :thinking:) Oh - what material is that? Just white acrylic?


#10

Yep, :proofgrade: White medium acrylic at stock settings.


#11

That is really cool.

I tell people that sometimes I work with a half a microliter. that boggles their minds. :slight_smile:


#12

I definitely don’t miss lab work! It was always pretty amazing though that moving around so many tiny volumes of clear liquid actually resulted in useful stuff.


#13

Wow … bet they were glad they came in for the gallbladder! There is nothing better than seeing something to understanding. Size is one of those things.


#14

Man, you never cease to amaze me. And, with this story and project, I’ll be sure to eat right and exercise regularly.


#15

My roommate works for the company that makes the DaVinci - when she was interviewing I was so excited cuz that machine is so frickin cool!


#16

A “pasta sizer” for who?!?
Would you like 1 piece of spaghetti - or are you gonna gorge on all 5?

Seriously cool story though. I hope it worked!

We have several daVinci robots. I’ve done a lot of work with them
