The Future of Radiology and Artificial Intelligence
What if an algorithm could tell you whether you have cancer based on your CT scan or mammography exam? While I am certain that radiologists’ creative work will be necessary in the future to solve complex issues and supervising diagnostic processes; AI will definitely become part of their daily routine in diagnosing simpler cases and taking over repetitive tasks. So rather than getting threatened by it, we should familiarize with how it could help change the course of radiology for the better.
Radiologists who use AI will replace those who don’t
There is a lot of hype and plenty of fear around artificial intelligence an...

Jimmy Kimmel Left Out Some Important Stuff About Obamacare
By BRIAN JOONDEPH, MD
Late-night comedian Jimmy Kimmel, in a recent opening monologue, spoke tearfully of his newborn son Billy, born with a serious congenital heart defect. Heart defects in newborns, while uncommon, occur in 1 in 100 births. The more serious ones, meaning those needing surgery in the first year, represent about a quarter of all congenital heart defects.
Jimmy’s son fell into the latter category, with Tetralogy of Fallot, bad plumbing in the heart, causing oxygen-poor blood to circulate out into the body without picking up a fresh supply of oxygen from the lungs. Hence the newborn baby turning...

Is it important to recognize LVH Pseudo-infarction patterns?
A middle-aged male called 911 for sudden severe chest pain. The medics were very worried about acute MI and recorded a prehospital ECG. It is unavailable, but looked like this:As with many prehospital ECGs, the R-waves on top,& the S-waves on the bottom, are cut off.There is ST elevation in V2-V4.The medics were very worried about MI and asked to see me at the door to assess the ECG.What do you think?I looked at it and immediately said: " This is LVH. Not MI. " And so we did not place the patient in the critical care area and did not activate the cath lab.What did I see? There is indeed ST elevation, but...

A 60-something with Syncope, LVH, and convex ST Elevation
Note 2 other similar cases at the bottom that come from my book,The ECG in Acute MI.CaseWhile I was busy seeing patients, a resident brought me this ECG of a 60-something with a history of syncope only. There was no chest pain or SOB at the tim of the ECG:Computerized QTc is 464 msA previous ECG from 8 years prior wasnormal.What do you think?There is sinus rhythm at a rate of nearly 100 (nearly tachycardic)There is 2.5 mm STE in lead V1 and 3 mm in lead V2, withconvexity, and 1.5 mm in V3.This meets " STEMI criteria "However, there is very high voltage, with a very deep S-wave in V2 and tall R-wave in V4.This is ...

8 year-old with report of " syncope and an abnormal ECG " .
This case was contributed byJohn Dunbar, an outstanding Hennepin EM Resident.A previously healthy, fully immunized 8 year-old African American boy presented with a report of " syncope and abnormal ECG " by EMS. On arrival to the ED, he was awake but lethargic with EMS report of normal prehospital glucose by EMS, HR in the 90s and BP ' s in the 110s/70s and O2 sats of at least 98% on room air. Immediately, a bedside cardiac ultrasound was performed while the ECG was being setup and this showed good global function, no effusion, no overt ventricular enlargement or septal hypertrophy (measurements not taken) and a ...

Who Won When the ACA Failed?
By ANISH KOKA, MD
You may have heard that repealing and replacing Obamacare recently failed. The analysis of what went wrong comes from many corners. Andy Slavitt, former insurance executive and most recent director of CMS, writes that the ‘failure of Trumpcare can be seen as a rejection of policies that Americans judged would move the country backward.’ Apparently, the theory goes, moderate republicans, especially in states that expanded heavily and rely on Obamacare Medicaid expansion, were skittish of a repeal and replace plan that endangered the healthcare of millions of constituents. The conservative Davi...

When do you use a tapering coronary stent ? Which company makes it ?
Coronary artery lumen has unique character . Its well-known LAD diameter is not constant , it tapers in its distal course.(Unlike RCA which is more tubular ) It is estimated LAD looses 15 % of its diameter for every 30mm length.Fortunately LCX has no such long course to make tapering a visible threat. (Though it may still be an Issue !)
Is there a hemodyanmic purpose for this tapering in LAD ?
Should be, God never designs anatomy without a physiological purpose.We have to find it out.(Can it be meant for flow acceleration as the flow is entriely diastolic in LAD while in RCA its both in systole ...

What is the difference between “ under-expansion & mal-apposition ” of coronary stent ?
Improper or technically deficient stent deployment is a major factor for post stent events .Few terminologies are used in assessing stent deployment.
Under expanded stent (UES)
A stent is not fully expanded to the desired or to its specified diameter.
This is often due to inadequate balloon pressure during inflation .
Many times its technical and It requires post dilatation.
Under-deployed stent is often due to a struts hitting a hard surface or calcium .
What is mal-apposed stent ? (MPS)
It’s a fine gap between the vessel wall and the stent.
It can be observed immediate or late. Immediate is usually due...

Echocardiography, even (or especially) with Speckle Tracking, can get you in trouble.
A completely healthy 30-something year old woman with no cardiac risk factors had sudden onset of bilateral trapezius pain that radiated around to her throat. It resolved after about 5 minutes, but then recurred and was sustained for over an hour. She called 911.EMS recorded these ECGs:Time 0:In V2-V4, there is ST elevation that does not meet STEMI " criteria, " of 1.5 mm at the J-point, relative to the PQ junction. But there are also unusually Large T-wavesTime = 13 minT-wave in V2 is now taller and fatter, the ST segment is more straight.T-wave in V3 is no taller, but it is fatter ...
