Corvia atrial shunt system: Mean LA pressure reduction device in HFpEF
Lowering the raised LA mean pressure is a major therapeutic goal in any severely symptomatic left heart disease, whether it is valvular or myocardial disease. It is prudent to understand, that even in systolic LV failure; it is the raised LVEDP that causes the symptoms and marks the limits of exercise capacity. Drugs like inotropes, pre-load , afterload modulators like diuretics and vasodilators can take care to a certain extent.
When symptoms are refractory and the underlying condition has no primary correction , we need to intervene with some extreme procedures. We know a small ASD decompresses mitral stenosis, and th...

Does the “ Non -IRA ” lesion status confuse you often ?..Try a blind primary PCI !
Primary PCI of IRA , continues to be a clinically & statisticaly validated (Inspite of some ifs & buts) coronary reperfusion strategy.
What to do, if we happen to detect, a significant or borderline lesion in non- IRA territory ?
There are too many guidelines scattered across cardiology literature either to “help or confuse” us. They argue for either immediate intervention , defer transiently, postpone or just ignore it , based on clinical ,hemodynamic*, Individual, institutional , or some other non academic factors. (Permanently deferred PCI is other wise called medical management is prac...

Ballooning an obstructed prosthetic Aortic valve : Can be a real tense procedure!
A 76-year-old woman with a history of double valve replacement (Aortic and mitral valves) for rheumatic heart disease, presented with acute dyspnea after a switch from Warfarin to LMWH before a planned bone marrow biopsy.
The investigations revealed a stuck aortic prosthetic valve ,that showed a prohibitive gradient of more than 50 mmhg. Since, she refused further surgery, a rare and risky effort was made to balloon dilate the prosthetic valve leaflet, though it is not a standard approved modality. It was decided to dilate the supero-lateral orifice and the central orifices by simultaneous kissing balloon. The results w...

How can Warfarin be safe “ even in ” first trimester of pregnancy ? The story behind the 5 mg cut-off !
The well known pro-coagulant state of pregnancy is an evolutionary protective process to make blood clot quicker, to save fetal loss in early pregnancy and mitigate postpartum bleeding. Still, in many women, this natural adaptive process confers an enhanced thrombotic risk. The molecular mechanisms for this pro-coagulant state are, there is increased factor VII, fibrinogen, reduced protein S. It is interesting to note, while plasminogen levels are elevated, D-dimer is also increased, indicating an ongoing fight between pro & anticoagulant forces, converting the physiological maternal- placental bed a mini harmless DIC ...

An anxious approach to a benign arrhythmia in Holter recording
A 32-year-old high-profile businessman was advised Holter monitoring for a few ectopic beats during routine screening ECG. The 72-hour extended Holter monitoring picked up a single short pause with a blocked P wave and reported as doubtful Mobitz type 2 AV block.
The cardiologist in-charge, told the patient that findings are significant, and he would need further investigation. He was referred to their associate center for an EP study. After hearing about the procedure ,the patient was freighted about inserting multiple catheters inside his heart.
This was the time he consulted me with Holter report. It was i...

What is the risk of ACS after PCI in a CTO related artery ?
CTOs are opened primarily for four reasons
Angina which is refractory to drugs
Stress test positivity with or without angina
Anxiety of having a blocked coronary artery in a self educated patient
Cardiologist’s clandestine pride & pursuit*
* Personal experience included
Some evidence based observation
Most of the studies as on today do not give survival advantage of opening a CTO.(DECISION-CTO,EURO-CTO,EXPLORE,IMPACTOR)
Opening a CTO, for reasons other than angina (i.e. for relief of dyspnea or improving functional capacity) is largely conjectural and based on randomly accrued data back...

Next frontier in radiation free Cath lab : Fibro-optic guided Catheterization
It is a 120-year challenge. Can anyone replace Rontgen’s X-ray discovered in 1895 for medical imaging? The Nobel winning Invention redefined the way we looked at our body and management of diseases for over a century. However, the fact remained it is an invasive and injuring investigation. What is the alternative for the X-radiation ?
CT scan was a great invention, but it turned out to be a gigantic 360-degree clone of X-ray machine. Today’s cath lab, however sophisticated , is like spending hours together inside a hot Chernobyl coffee shop. MRI was a true game changer. With zero radiation, MRI came close i...

No, we can ’ t call OMT, as a re-vascularisation procedure.
Hi, welcome Mr George, I just reviewed your records. You have three blocks in your arteries supplying the heart.
Are they serious Doctor ?
Not really, but one of them appear tight
What should I do Doctor ? But, I am comfortable Doctor.
You may be. But I am not .You need to undergo some re-vascularisation procedure .
What do you mean by that Doctor ?
It means either a percutaneous coronary intervention with a stent or CABG.
Can I get my heart re-vascularised by drugs alone Doctor ?
No we can’t . Hmmm , wait, we do have something called OMT/GDMT. Can you put on hold for some time Mr George, ...

When medical conferences become an “ Edutainment Industry ” the speciality of Cardiology leads from front !
Recently , I received two e-mail invite for two major conferences one in India other in Europe.
Once upon a time, in 1990s we as fellows used to attend these conference for Rs 1000 (15 Euros/Dollors). Now it is 50-75(5000-7500%times increased) Even few years ago it was affordable. I don’t know how many of us can think to attend such conferences. Definitely not me. What prevents these guys to keep the cost nominal. Certainly, Inflation is not the reason. Air tickets and hotel room tariffs has just raised 50-100%.over the same period

Why ICDs are less effective in Non Ischemic DCM ?
We wish, our understanding about cardiac contractile physiology is deep and nearly complete. Heart is an irreversibly coupled electro-mechanical organ , right from the fetal days until the final heart beat. In myocardial pathology, the genesis and sustainability of ventricular arrhythmia are intricately related to the degree of LV dysfunction of any cause.
SCD is the leading cause of mortality in heart failure. Tackling SCD was in God’s domain, until the brilliance of Dr. Michel Mirowski shrunk the defibrillator and implanted it under the chest in 1980. (Dr. MM’s s a unique and inspiring story, from Poland a...

Predicting myocardial viability from surface ECG following MI
Once upon a time, long, long ago, cardiologists used to be worried about akinetic segments, scars, dead tissue, and Q waves before attempting revascularization by either PCI or CABG. Now, the concept of myocardial viability has become a cliché ( rather demeaning) at least within the cath labs. Currently ,we follow a self administered whip . Every post-MI patient should be considered for revascularization as a default strategy irrespective of the level of dysfunction or scarring .This can happen either in the IRA territory or non-IRA territory or both.
This strategy is now dis-armed with fresh evidence in the form ...
