✅The innominate artery is the most commonly injured branch vessel. Mechanisms of injury have been attributed to shearing and compressive forces occurring near the junction of the aorta and the branch vessel.

✅If pericardial rupture is large enough, then herniation may occur. Herniation with pericardial rupture is highly lethal leading to strangulation from torsion of the SVC and/or great vessels.
#RGphx

✅Hemopericardium is the most common imaging sign in patients with cardiac laceration. Any pericardial fluid present, must be assumed hemorrhagic unless proven otherwise.
#RGphx

✅Myocardial contusions are common in blunt cardiac injury and may be present in 24% of patients with blunt trauma. Although CT is not a first-line modality, the radiologist must recognize direct and indirect signs.

Congrats to MI Prof Dr. Elsie Nguyen & her team of Cardiothoracic Imaging Fellows, whose abstract, titled The Thick of It: Approach to left Ventricular Hypertrophy on Cardiovascular Magnetic Resonance, was awarded the ARRS 2026 Bronze Award for the ARRS 2026 Annual Meeting and Scientific Program!

📌 CT-Based Phenotyping of Bicuspid Aortic Valve: Diagnostic and Clinical Insights

Accurate phenotyping of the bicuspid aortic valve (BAV) is essential for clinical decision-making, yet echocardiography often shows limited agreement with true valve morphology.

3D volume rendering in cardiac MRI can show heart tissue and blood flow together — helping clinicians better visualize congenital heart defects and inform treatment.

It’s a powerful tool for clearer imaging without radiation. Read more: https://bit.ly/3OnPGUh

Spectrum of Interatrial Shunts Presenting with an Intact Atrial Septum: Imaging Features at Echocardiography, CT, and MRI | Radiology: Cardiothoracic Imaging Interatrial shunts across an intact atrial septum encompass a range of anomalies that have clinical and hemodynamic implications for management and outcomes if left untreated.

✅“Shunting via unroofing of the CS, anomalous or decompressing veins, or a combination of multiple anomalies may result in interatrial shunts with INTACT atrial septum”

Imaging Guidance in Structural 🫀 by Drs Atkins, Radike, and Rajiah

✅Wide aortic-mitral angle = ⬆️ risk of LVOTO in TMVR
✅⬇️ distance of RCA from TV annulus (❌ if <2 mm) = ⬆️ risk of compression in TTVR
✅ >/= 5 mm gap ➡️ relevant PDL for LAA closure

Amazing case of Proximal Interruption of the Pulmonary Artery from Dr Arzu Canan

✅Asymptomatic, incidentally detected
✅The affected lung may go on to develop a fibrosing ILD
✅ Consider chest CTA for PAs and cardiac CTA for PVs assesment

Challenging Aorta by Dr Trabzonlu

✅ULP (communicates with blood pool) vs Intramural blood pool (doesnt communicate), former = ⬆️ adverse events
✅Periaortic stranding = first sign before mycotic aneurysm
✅Scrutinize plaque or thrombus for possible intimal sarcoma❗️

Happy that #RSNA24 organized an IRIYA alumni reception. Wonderful to catch up, reconnect with my cohort (2022), and learn about the many opportunities that came our way after participating ⭐️

The IRIYA world is also small as I work with some of them in NASCI and #RGTeam

ICYMI 🔑 in CAD #yescct session by Drs Vliegenthart, Ghoshhajra, Agarwal, and Schoepf
✅ Qualify CAC in plain chest CT
✅ Use multiple views, especially in LM dx
✅ CADRADs score does not replace the impression, give context
✅ FFR-CT is helpful and seeing ⬆️ use

Practical takeaways in measuring the thoracic aorta from Dr Nick Burris
✅High quality imaging of the aorta is 🔑
✅Consistency in measurements (outer wall, inner etc)
✅Look out for the commissural🔺, absence = raphe in BAV
✅Talk to clinicians in difficult cases

Takeaways from S5-CCH03 by Drs Andrea Oh, Rachel Putnam, David Lynch, Jonathan Chung
✅Fibrotic ILA and ILD are a spectrum
✅ILAs ⬆️ risk of death
✅Beware of 🚬 related ILD; diff SRIF from UIP
✅Look out for high risk populations, CT can be similar to ILA
