Calcium Scan and Subtractive Medicine
By SAURABH JHA MD Being a radiologist, I rarely speak to patients, but I was asked to counsel Mrs. Patel (not her real name, so calm down HIPAA totalitarians), who was worried about the risks of radiation from cardiac calcium CT scan. Because of her risk factors for atherosclerosis, her cardiologist wanted her to take statins for primary prevention, but she was reluctant to start statins. They eventually reached a truce. If she had even a speck of calcium in her coronary arteries she would take statins. If her calcium score was zero she wouldn’t. This type of shared decision making is the most frequent reason why cardiol...

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...

Timothy syndrome – Cardiology MCQ
All of the following are features of Timothy syndrome except: a) CACNA1C mutation b) Named after Katherine W. Timothy c) Phase 1 of action potential is affected by gene mutation d) Multisystem disorder Correct answer: c) Phase 1 of action potential is affected by gene mutation Cav1.2 calcium channel is affected by CACNA1C mutation in Timothy syndrome. This channel is important in the phase 2 (plateau phase) of cardiac action potential. Timothy syndrome is characterised by marked prolongation of QT interval, syndactyly, congenital heart disease, cognitive abnormalities, and intermittent hypoglycemia. It is designated as LQT8.

Ranolazine – Cardiology MCQ
Ranolazine is: a) Inhibitor of late sodium current b) If current inhibitor c) Potassium channel opener d) Calcium channel blocker Correct answer: a) Inhibitor of late sodium current In addition this ranolazine is a partial inhibitor of beta oxidation of fatty acids. These two mechanisms account for its anti anginal effect. Ranolazine is also increasingly being tried for its anti arrhythmic effect. In this respect it has historical similarity to amiodarone which was initially introduced as an anti anginal agent and later became known as a broad spectrum anti arrhythmic agent.

ST Elevation. What is it?
A young woman was  found down, unresponsive, with legs crossed.  She was intubated by medics.  A prehospital EKG (not found, but reportedly identical to the first ED ECG below) was read as ***STEMI*** and after prehospital cath lab activation, the patient was transported to the ED. On arrival, she was mechanically ventilated and not in apparent shock.  Here is the ED ECG: This is a pathognomonic ECG.  The computer reads the QRS duration as 133 ms.  I have posted several of these in the past. What is it? Answer : it is pathognomonic of severe hyperkalemia.  The do...

Beta-Blockers for Cocaine and other Stimulant Toxicity
Dogma: “a belief or set of beliefs that is accepted by the members of a group without being questioned or doubted; a point of view or tenet put forth as authoritative without adequate grounds.” Years ago I treated a university student who presented to the emergency department (ED) after drinking several cans of a popular caffeinated energy drink to “pull an all-nighter” during final exam week. He was tremulous, agitated, and pale, with sinus tachycardia ranging from 140 to 160 bpm and normal blood pressure (BP). The house officer (registrar) working with me that night proposed treating him with a benzodiazepine, bu...

Resuscitated from ventricular fibrillation: what is the ECG Diagnosis?
A reader (someone in training) sent me this ECG, and asked for my interpretation.Clinical info:  "The patient was found down in cardiac arrest, defibrillated with ROSC in the field, was unconscious on arrival. Attached is the initial ED ECG.""I will provide details and outcome to come after your impression." Here is the EKG: Here is my interpretation: Sinus at a rate of about 80, RBBB, LAFB, ST Elevation in aVL, reciprocal ST Depression in II, III, aVF.  No precordial ST Elevation, but STE often does not show in precordial leads when there is LAD occlusion with RBBB and LAFB.  Proxim...

A Perfect Resuscitation Saves a Patient with Refractory Ventricular Fibrillation
This was contributed by Dr. Johanna Moore, one of my Hennepin Colleagues who researches CPR, along with Keith Lurie and Demetris Yannopoulos.  She translated her research knowledge into a spectacular resuscitation.Case A 54 year old male presented via ambulance to the Emergency Department (ED) in cardiac arrest. He was found down outside a clinic, where bystander CPR was initiated by clinic staff. The amount of down time was unclear but thought to be minimal as this was a high traffic pedestrian area. He received an estimated 5 minutes of manual CPR, then, after medic arrival, 20 minutes of LUCAS CPR, including u...

Sutureless AVR : Surgeons shed the needle . . . to take on TAVR !
With TAVR (Transcutaneous aortic valve replacement ) threatening to take away the Aortic valve surgery atleast in high risk subsets from surgical domain ,a new development is taking place in aortic valve surgery. Minimally Invasive aortic valve replacement and implantation of low profile , bio prosthetic valve placed in aortic root without active suturing .This type of AVR  can be done without traditional  sternotomy  with minimal bypass time , less surgical morbidity and mortality. It has some specific advantages over TAVR, as the native valve is removed , calcium is debrided and hence less stroke and para-valvular lea...
