🧵How to use #yesCCT data to perform low contrast coronary angiogram 👇

📌Patient below w/ #CKD, unknown graft anatomy. Used prior CT data to perform cor angio + bypass graft angio with minimal dye🪡

Read 8 pointers below🧵1/4

#CardioTwitter #ACCFIT #Cardiology #MedTwitter

🔥Key considerations 👇

1. #RadialFirst >> #SafeFemoral, but if doing femoral, can avoid femoral angio by using ultrasound pre, during & post sheath placement

2. Review CT. Look at native coronaries, including origin (e.g. anterior take off), any ostial disease etc

🧵 2/4 Image
3. Identify exact location of graft ostia in relation to sternal wires🍥

4. Use saline injections to confirm engagement (T wave changes) if normal pressure waveform💉

5. Print out CT info, and paste it on the screen so you could use it as a map during the case

✨Cardiac Sarcoidosis (CS): AHA just dropped an enlightening Scientific Statement! 📜

#Tweetorial below for all u need to know about CS: Epidemiology, Diagnosis & Management 💥

🧵1/12

#CardioTwitter #Cardiology #ACCFIT @CircAHA @AHAScience @BCMHeart @AKUGlobal #MedTwitter Image
💥2/12: Etiology of Sarcoidosis

1. Exact cause unknown
2. Likely triggered by antigen exposure (e.g., mold, insecticides, silica dust)
3. Genetic predisposition plays a role🧬
4. Family history ⬆️ risk Image
🛡️ 3/12: Immune Dysregulation in Cardiac Sarcoidosis:

1. Starts w/ type 1 T-helper cell activation
2. Leads to Up-regulation of cytokines & chemokines
3. Activates macrophages
4. Forms non-necrotic granulomas
5. Progresses to active inflammatory phase
6. May lead to fibrotic phase
7. Both phases contribute to cardiac dysfunction 💔Image

🔥#Tweetorial on "Invasive Hemodynamic Assessment for Constrictive Pericarditis"👇

Rule of 3s 🦢👁️
🔹3 RA findings
🔹3 RV findings
🔹3 simultaneous LV-RV findings
🔹3 miscellaneous findings

#CardioTwitter #Cardiology #ACCFIT @BCMHeart @ACCinTouch @txchapteracc @SCAI

🧵 1/8 Image
🧵2/8 Few general points

🧿Make use of exaggerated respiration (have patient take slow deep breaths in & out)
🧿Avoid holding breath (can induce Valsalva & alter your measurements)
🧿Use a respirometer & multiple pressure transducers
🧿Multiple long recordings (be patient)
🧿Afib or ectopy: pace for regular rhythm
🧿Induction of PVC can be helpful 🙌
🧵3/8: RA: 3 key measurements:

1. Baseline pressure (generally high. If very low, consider saline loading ~ 1L)

2. Y-descent (more prominent in inspiration): due to rapid emptying of RA during early diastole (Friedrich sign)

3. Kussmaul sign (next slide) Image
