What's going on with the Impella?

As a follow up to my previous #tweetorial on the IABP, this🧵 will explore the nuts and bolts of the Impella for those in the CCU

Special thanks to @AHajduczok for helping with this🧵.

Can heart transplant recipients experience vasovagal syncope??

This came up during my time in the CCU, here's a short 🧵 investigating this question. Special thanks to @AHajduczok of @TJHeartFellows.

Let's first start with how vasovagal syncope normally occurs... It starts with a trigger (stress, pain) coupled with central hypovolemia (dehydration or upright posture) → ⬆️ contractility of an underfilled LV

This ultimately results in ↑vagal efferent activity to sinus node (↓HR) and ↓sympathetic efferent activity to arterioles (↓SVR)

What's going on with the intra-aortic balloon pump (IABP)?

Here's a practical🧵 for all residents and fellows during their time on rotation in the cardiac ICU.

#CardioTwitter #Medtwitter #tweetorial Let's start with the basics.

Developed in the 1950s by the Kantrowitz brothers, IABPs have been in clinical practice since the first implant in 1967 at @MaimonidesMC Currently, it is still widely used as modest temporary mechanical circulatory support for cardiogenic shock
