Cardiology classics : Bernard Lown . . . The cardiologist who won Nobel “ peace ” prize !
Great men dream , but they just do not sit idle. They do what they are passionate about .History just follows them or they create it.Here is a brief story of an ordinary man born in a small European country Lithuania in 1921 ,lived much of his life in the east coast of USA ,transformed into a brilliant cardiologist based in Brigham Hospital , Boston.
He is Dr Bernard Lown , best known as a founder of what is used in every coronary care unit and cardiac surgical theaters around the world . Yes, the DC cardioversion was invented by Lown in the year 1961.(Of course, it was an Improvement upon the pioneering work ...

Baremetal stents where are you ? , . . we need you desperately !
Its a funny world out there in medical science, more so in the field of cardiology ! A new treatment comes as a revolutionary breakthrough , lives merrily for a while . . . only to blink , few years down the lane . . . and make a sheepish exit !
Here comes some important knowledge from Rome , European society of cardiology conference 2016 .Its the much expected NORSTENT study from Norway,with a largest number (9013 patients comparing one to one BMS vs DES ) with up to 6 year follow up data ,exposing the limitations and the possible false superiority of DES over bare metal stents .It almost concludes there is no meaning...

Balloon Aortic valvuloplasty (BAV) will be back with a bang . . . should pose a genuine threat to TAVR !
SomeInterventional Cardiologist’s favorite play time is to get rid of of obstructions across any blood vessel , valve or a conduit . This has been well practiced for over 2 decades in both coronary and valvular obstruction.Now they wanted more and have since started implanting valves percutaneously. (Aortic valve -TAVR in particular )
Why do balloons work in Mitral stenosis but not in Aortic stenosis ?
It remains a mystery at-least to me ,how PTMC (Percutaneous mitral commissurotomy ) became a default strategy for relieving mitral valve stenosis, while BAV (Balloon Aortic valvotomy) was never consid...

Primary prevention of CVD with Aspirin : The confusion need to stop here . . . but it may not !
Aspirin for primary prevention of CVD is an ongoing controversy for more than 2 decades. Please note, the controversy is not in the competence of Aspirin to prevent cardiovascular event, but in the potential risk of GI bleed and whether that risk is worth taking. Secondary prevention has no such issues as the benefits easily outweigh the potential bleeding risk .
Male vs female
There is a “gender” and “age” difference in the ability of Aspirin to prevent vascular events.Aspirin primarily prevents MI in men(>45) and stroke in women(>55) (Funny it may look, that’s what data says!...

Wait. . . New generation TAVR is coming . . . and its called Lotus valve !
The concept of TAVR(Trancutaneous aortic valve replacement ) is trying hard to prevail over surgical aortic valve replacement .Two companies Medtronic and Edwards life have their products (Core and Sapiens) tested and used with varying success.Meanwhile, Boston scientific has come out with a new one , Lotus valve made with stainless steel and bovine pericardium.
Lotus valve seems to have a distinct advantage* (over the Core and Sapiens ) in terms of easy delivery and adjustment (or retrieval ) of valve till final position and efficient adoptive steel technology in preventing para-valvular leak.
* Outcome ...

Ignorance based STEMI care : What is the optimal gap between “ Pharmaco ” and “ Invasive ” strategy ?
Less than a century ago an easy chair was enough to manage this most important medical emergency of mankind. Of course, at that time mortality of STEMI was estimated to be around 30%.We have since pushed the in-hospital death rate down to less than 10 % and its around 5-8% currently.(*The lifeless chairs were able to save 70 lives is a different story!)
Heparin , thrombolytic agents, critical coronary care has helped us to achieve this , of course It must be admitted primary PCI also played a small role (at best 1 % ) in our fight against this number one killer.
Now, why not combine both lysis and PCI ?

My dear physician , don ’ t feel ashamed to prescribe Digoxin for Atrial fibrillation !
It was delicate few minutes in one of my recent visits to a corporate hospital , when I noticed an emergency physician hesitated to follow my advice to prescribe IV Digoxin for a patient with Atrial fibrillation and fast ventricular rate.His fear was, his consultant, a modern day cardiologist wouldn’t like it as Amiodarone has become a default drug for atrial fibrillation in that Institution. I could sense. . .he felt so out of place to take on my suggestion.
I reminded the young physician , the uniqueness of Digoxin and its un-diminished value for this particular indication ,still he was rel...

Could Ablation for AF Be an Elaborate Placebo?
We know, atrial fibrillation is the commonest clinical cardiac arrhythmia , that is extensively studied , subjected to exotic investigations and state of the art treatment strategies.Interestingly , this arrhythmia also drags the economics of cardiology practice of a community in a big way with heavy influence on drug , device and usage.We know, RF ablation of pulmonary vein is one of the modern ways to manage this arrhythmia.
Iam sharing this article from medscape by an EP specialist Dr. Jhon Mandrola , surprisingly exposes our fundemental ignorance about this arrhythmia and the near futility of certain procedures.

Don ’ t hunt for non-existing culprits in STEMI crime scene !
Scientific cardiology has forced us to believe ACS management must be catheter based and all others are inferior and those who pursue the later , carry a risk of being labelled as unethical in near future. However ,experienced cardiologists will know where the truth lies.
Now,in the interventional cardiology board rooms there is a big debate going on regarding the value of early total revascualrisation in STEMI with multivessel CAD.Suddenly , every lesion looks suspect ( Ex,current or future culprit ! ) and all stentable lesion are stented either in an emergency or semi emergency fashion (The new age post PC...

Yes, Its official , medical mistakes consume more human lives . . . and threaten to displace cancer and heart disease for the top honor !
We all know to err is human , but most of us probably won’t agree medical mistakes , (bulk of which happen in the name of practicing state of the art of science ! ) could be the dominant theme in modern medical care !
BMJ exposes this well known secret with the help of most authentic data from an apex scientific body CDC , Atlanta .

Which is the “side branch” for Left main ?
Bifurcation lesions (BFL) remain a true challenge to interventional cardiologists. For over two decades , at least a dozen strategies are being tried to conquer it without true success
. . . if iam allowed to say that.
We often we talk about side branch in BFLs.Ironically , the importance of side branch is largely determined by our cortical linguistic perception of the word “side”
The much famed Medina classification does little to clarify the importance of side branch with reference to left main vs non left main bifurcation lesions.
In true sense , both LAD or LCX can be side branches in left main BFL dependi...
