Life style modification & CVD prevention : Spot the new entry
Discussing lifestyle modification is an essential cliché in every preventive cardiology consult, For most, it still means good nutrition exercise, and stress relief. It is true, that the average human longevity has increased considerably in the last century. However, this apparent gain in life expectancy by the stunning discoveries in science ( 10 years ?) has already been eaten up, by the self-inflicted,  poor styles in life. The new kid on the block, i.e. social media is playing a powerful amplifying effect. Spot a new entry in lifestyle interventions. Here is a fresh list of lifestyle modifications from the ...

Dip and plateau pattern of ventricular pressure tracing in constrictive pericarditis
Thickened and stiff pericardium in chronic constrictive pericarditis has poor compliance reducing the distension of cardiac chambers to a limited fixed total volume. Transmission of intrathoracic pressure to the pericardial cavity is also prevented by thickening of the pericardium [1]. Manifestation of compression occurs when the total cardiac volume reaches the pericardial volume in diastole. The severe restriction causes elevation of pulmonary and systemic venous pressure which becomes equal to diastolic pressures in all cardiac chambers. Relative change is more on the right sided chambers. Inspiratory fall in intratho...

Stent migration : A rare & tricky complication !
Stents have become essential coronary jewelry in global CAD care. The usage of these glamorous metals inside the human heart has crossed many millions, and aiming for a billion. Obviously, when used on such a large scale un-toward events are not an exception. Stent migration While the complication list of coronary stenting hangs long, fortunately, stent migration is a rare event. , Though, early geographical miss is common during deployment, these episodes don’t come under stent migration. Stent dislodgement during the procedure is a more common technical defect.If not recognized it may be wrongly label...

Operation Searchlight: The American-supported Pakistani genocide you probably haven ’ t heard about
BY ANISH KOKA On March 25th, 1971, the Pakistani army launched Operation Searchlight, a military campaign to brutally suppress a Bengali nationalist movement. The roots of the genocide lie in the parting gift British rulers gave to the Indian subcontinent at the time of independence in 1947. British controlled India was separated into Hindu majority India and Muslim majority Pakistan. But because there were two dense non-contiguous Muslim majority areas in British controlled India, the muslim majority country of Pakistan was divided into East and West Pakistan. East and West Pakistan were linked by religion, b...

A “ hard talk ” with chat GPT : Evidence vs Experience in medicine
Dr .S.Venkatesan MD Good morning GPT. Let me introduce myself . I am a medical doctor, practicing cardiology, in Chennai India. I have had a long-standing query in very fundamental principles of the practice of medicine. Just wanted to chat and clarify with you. Welcome, I am here to help you Medicine is both art and a science. In recent times the movement of evidence-based medicine (EBM ) is trying to overturn the clinical experience. I have a feeling it is not fair. We can’t create evidence for every decision we make in clinical science right?  My first question is  Can experience-based medical care be...

Localisation of Ventricular Tachycardia by Surface ECG
Surface ECG can be used to identify the site of origin of ventricular tachycardia. QRS morphologic patterns and vectors are helpful in discerning the activation pattern of the myocardium. Chest wall deformity as well as metabolic and drug effects can cause limitations in analysis sometimes [1]. Identification of site of origin of VT is useful while planning catheter ablation. It is also useful in correlating with the clinical situation as in post myocardial infarction scar related VT. Another instance is for correlation with findings on imaging modalities like echocardiography and cardiac magnetic resonance imaging [2]. F...

ERS pattern in ECG : New-onset “ Iatrogenic panic ” is unwarranted !
This is an ECG of a 25-year-old, recorded in master health check-up.  It was reported as ERS pattern of concern. When he went for an expert opinion, he was suggested to understand, there is a small risk of SCD. That’s it, the panic has set in already, which got amplified in the following conversation.. How small is the risk,?  he wanted to know. Yours’ is possibly an intermediate risk. Intermediate means what?  Do I have any genetic or EP studies to predict the risk accurately? Sorry, we have some gene mapping but all primitive. We aren’t sure. But keep calm, nothing will happen. Do I nee...

Epsilon Wave
Epsilon wave, the classical ECG finding in arrhythmogenic right ventricular dysplasia is seen at the end of the QRS complex. Epsilon wave is typically seen in right precordial leads though it has been noted in left precordial leads in those with left ventricular involvement. ARVD is better termed arrhythmogenic cardiomyopathy because of the possibility of left ventricular involvement. Epsilon wave represents the delayed activation of surviving islands of myocardium within the fibrofatty tissue in ARVD [1]. Some have called it as a ‘post excitation’ wave, as a corollary to the delta wave in pre excitation. It ...

Department of artifact : Normal “ wall motion defect ” in echocardiography
(This post is about some basics in echocardiography meant for fellows, and echocardiographers. Others can skip please )  This is a 27-year-old woman who was referred for routine* cardiac evaluation. What do you see? What is the diagnosis? This echo clip is from a woman who is 8 months pregnant. What you are seeing is perfectly physiologically and normal. On lying down there is a mechanical push of the diaphragm altering the LV shape and contraction. In the short axis, the left ventricle is contracting well, but the shape is not spherical in systole implying some desynchrony. Further, the  IVS arena is contract...

Awake ECMO
Extracorporeal membrane oxygenation (ECMO) is used for treatment of severe respiratory or cardiopulmonary failure. Usually these patients are sedated and mechanically ventilated, though at lower tidal volumes to reduce lung injury and permit lung recovery. The concept of Awake ECMO is to do away with mechanical ventilation permitting the patient to eat, drink, sit up and even possibly walk. They can also participate in physiotherapy. One situation in which it is considered is in those who are in bridge to transplantation situation. One study documented 6 month survival after lung transplantation as 80% in the awake ECMO g...

Pathological VVI pacing pips DDD,.. one more time in the EP race !
This study reaffirmed the lack of appreciable hemodynamic and clinical benefits with DDD mode yet again.  We have also contributed a little on this issue. It was found cardiac failure in VVI pacing was not a real big issue in the long-term follow-up. We presented and published in world congrees of cardiology Dubai 2012, and Circulation journal.  How is that? A dual chamber pacer with AV synchrony fails to show a hemodynamic benefit? The answer is simple..VV desynchrony is a common denominator for both VVI and DDD pacers. Providing AV synchrony without VV synchrony doesn’t make real sense in the long term to ...
