Dear Dr V,
Thank you so much for taking your time to share your knowledge with us. I’ve been searching for websites with info on nutrition, health and the body. Since my health has improved I’ve spent most of my free time reading and learning. Some of my issues involved my heart so your blog is excellent learning material. Can you suggest a book, or a dictionary of cardio terms? I’m not a Dr, just someone wanting to understand.
What a blog!
Hi Dr Venkatesan.
Have you performed animal studies to support your ideas regarding pericarditis as a novel treatment for CHF?
If not, are you aware of anyone who is performing such studies?
Kindly
Thomas Kjeld, M.D

Dear Dr.Venkatesan
Great work sir!!!!!
It is never enough to say thank you for such work and I do appreciate the precious time you spent to make this blog. I wish you all the best
Thank you for your dedication to emphasize to obvious , which has been lost with passage of time, now it’s fast food cardiology.
Dear Dr.Venkatesan, the contents of this blog is very much useful to highly qualified medical professional (Cardiologistys) and layman like me. This also helpful for medical students, where they only rely on text books. Apart from this, every comment made by you is higly appreciable. It shows your in depth knowledge in your filed.
Thanks

Wonderful..Thank You.
I stumbled on your blog and was floored. Absolutely phenomenal. You are a genius, My best teachers were from India. You guys are brilliant! Ten-thousand years of culture while my ancestors were scrapping charred meat off a bison bone in a cave in northern Europe. The world has A LOT to learn from you all.
Thanks, and please keep up the extraordinary and very helpful work you do, and the way you distill the essence of the problem, making it easy for us feeble minded primary care Neanderthals to at least for a flicker of time experience a higher plane of insight, coming away with hope that we may be able to employ some of this wisdom to the benefit of our patient’s.
Then again, we can just get a consult LOL 🙂
Seriously, very helpful, thank you Ken
.
A really helpful blog. I will recommend!
Sir,
I need your contact information. I am residing in Kuwait and would like to see you when I visit there
Dear Dr.Venkatesan
I received a letter from my hospital to my GP about my recent ecg. The words ‘trivial regurgitation only’ followed by ‘an extremely reassuriing test’ put me at ease but what I wondered regurgiation meant. I had been told in had a very minor heart murmur when I was in my twenties and thought nothing more of it but after an episode of severe chest pain lasting over an hour and a half sought medical advice. Hence the ecg amoungst other tests.
When I received the letter I did a quick search to find out what it meant and found your blog and am so very pleased I did. Your straight forward, factual approach gave me the information I wanted.
A very helpful blog, thank you so much for taking the time to research and write it. Trish, England
I am not a medical person. I have been reading your posts for some time now and they are interesting. Since I had an MI and have a stent, it is easy for me to relate to some knowledge shared by you.
Sorry for pointing out a silly ‘autocorrect’ . Did you mean ‘sanctorum’ here? https://drsvenkatesan.wordpress.com/2012/03/02/can-we-shoot-the-left-main-at-the-bed-side/
Thank you very much for the informative articles.
nice blog helping a lot
Dr Venkatesh
I am highly highly thankful to you for launching such a great website for us who are doing there residency in Cardiology to get fully trained. Once again thanks alot.
Can you help me to differentiate Syncope from Aortic Stenosis and Syncope from Other causes. How we will proceed in a situation where patient presents with history of syncope and Moderate stenosis?
Thankz Aloy
Wonderful job, so practice, thank you so much

hello sir, your work is wonderful
This is a wonderful site with practical knowledge. I found it by searching for an explanation of post stenotic dilitation, a much bandyd term which I have never understood physiologically.
Dr. V clearly understands that we must continually be aware of the past to function effectively in the present.
Sir,
Your blog is really wonderful. I request you to explain the physiology of JVP and Kussmals sign and the correlation of echo finding (echo talks about respiratory variation while kussmals is explained with on basis of non transmission of negative pressure produced by inspiration ) in constrictive pericarditis……please clarify
Sir,
I am very happy to see your blog. It is very informative & useful.
Sir, recently on dt. 01 Aug.,2013 I had got my Echocardiography done, the report of which shows following abnormalities:
Left Ventricle- Normal sized cavity.
No RWMA.
Good systolic function with ejection fraction 65%.
Grade I diastolic dysfunction.
Mitral Valve: Normal. No MR.
Tricuspid Valve: Normal. Trivial TR.
others No PAH.
Rest of the things are normal.
Under the situation, I want your suggestions. what should I do. What precautions I should take. Which medicines I should take.
Thanks,

Dear Dr. Venkatesan,
I need not repeat that this is a great website and a fantastically educational one at that. I appreciate the availability of valuable knowledge through this website.
If you could take time to answer…I wanted to know more about LV dysfunction, how does the cardiothoracic physiology change after a pt develops severe lv dysfunction…can a patient with sev. lv dysfunction (post Mi) be advised incentive spirometry for basal atelectasis after he has recovered from acute pulmonary edema caused by valsalva maneouver(straining during defecation).
The decreased intrathoracic pressure caused by deep breathing will increase the venous return…now will that help the heart by increasing preload and thus increasing cardiac output, or will it cause volume overload (which a dysfunctional lv may not be able to pump)–back pressure–pulmonary congestion and aggravate pulmonary edema?
Hi
That’s a Interesting thought. Heart acts as a serial pump even though the two ventricles are make it appear parallel .One of the principles in the management of cardiac failure would be to reduce the preload.(Diuretics does this effectively) .So any vigorous inspiratory effort would increase the preload Having said that , in a stable CHF this may not be a big issue as starling forces will still be operating .Only during acute cardiac failure loading conditions are more important .It should also be understood for blood to flood the lungs it has to cross the RV. If LV dysfunction is grossly out of proportion to RV congestion is more likely. In severe RV dysfunction lung is ironically protected .
Venkatesan
Thought provoking question from Swetha . very well briefed by Dr. Venkatesan. Sir your blog is superb and now a days no one of your caliber would spent time for sharing the knowledge freely. A big salute and thank you so much for this blog. Your blog is inspirational.
I would like to submit a video of angiography test of Male (age 67) for your study material. Spreading knowledge is a great job. This video is FREE from any copyrights. No issues.
Your blog sir has been an immense help to me especially during my ICCU posting.
Thank you .
Dear Sir,
happy new year to u
I have one question- Why some RHD patients develops MR, others MS, or mixed? Are there determinents? genetic.
Dear Sir,
if we have any question or share/ Discuss any ECG/ CXR/ INTERESTING ECHO, how should we approach
thanks
I especially loved your blog on microcircualtion! I shared it on my Facebook info page for Coronary Microvasvular Disease!
Good initiative.
Plz keep ne in touch.
Thanks sir.

Dear Dr.S. Venkatesan,
Though I am not from medical fraternity , being a heart patient [PTCA in to RAMUS] I read your blogs / briefing with great interest. Since long I was trying to get understand the meaning / function of RAMUS and other vessels etc. Now after reading your briefing I got clear idea. Your writings are definitely useful for all from Medical fraternity but these are also useful for patient like me who is interested to know where the things have gone wrong etc.
I am based in Pune, Is it possible to have your opinion on present heart problem , if I send you all the details on e-mail etc. I am ready to pay your fees etc.
With Best Regards,

Dear Dr Venkatesam,
I was pleased to read one of your blogs and intend to revisit this site again and probably again and again. I have a personal problem to discuss with some one who is qualified and knowledgeable. I felt that I should discuss with you provided you are willing to entertain.
Thank you

I have come here to research a few findings I have from an echo and ECG. After reading so much information here, I am too overwhelmed to figure any of my stuff out. What I can tell, is that you have put much effort into this site and for that I am grateful. — patient in search of answers.
Hello sir,
My 3 month old son has been diagnosed with a subpulmonic vsd of 3mm. Sir, is there a possibility of spontaneous closure? Can it be closed by catheter or is open heart surgery the only option to treat him. He does not have AR or AVP currently. Thank you in advance for replying to this very worried mother.
Dr Venkatesan replies the VSD of your child is small and likely to close. Needs follow up .Advices to meet a paediatric cardiologist.
Thank you soo much sir for replying. Sir, can a 3mm subpulmonic vsd undergo spontaneous closure? We were told that subpulmonic vsd does not close spontaneously. Sir, please throw some light on this. I am extremely worried and terrified that my 3 month old will need open heart surgery .
Sir, thank you soo much for the reply. Sir, can a subpulmonic vsd undergo spontaneous closure… We were told that subpulmonic vsd does not close naturally… Please throw some light on this. ..I am extremely worried for my son
Dear Dr. Venkatesan,
I read your article about heparin as a thrombolytic agent. It was very comforting since I wasn`t sure the treatment, a livingbeing as we too, our cat, received.It had an primary aortic thrombosis and I was skeptical about the heparinization as the immediate measure, the vets have done. My first thought was a treatment with a kinase.
Thank you, Dr. J. Kuruvilla
We need more medical blogs like this!
Dear Dr. Venkatesan,
I am a registered invasive and noninvasive specialist and run a few websites Is there a way that we can discuss sharing some of your images on the websites? I have learned a lot from your blog/website about the minute details of chest x-rays in cardiovascular disease and would like to present them in the courses that I write.
I enjoy the philosophical discussions that you include in your posts. Always positive and thought-provoking, I wish there were more websites from people like you that conveys our appreciation of being in the medical field and the opportunity of teaching others.
If you would contact me, I’d like to thank you for what I have learned and to see if you would be interested in my project.
Best regards,

Dear Dr.Venkatesan:
I have had two events regarding my heart (as a patient). In 1993, I was diagnosed with 90, 80 and 70% blockage in three coronary arteries. On June 3, 2017, I was diagnosed with 100% blockage of the left coronary artery. In 1993, I entered a study at Methodist Hospital and, after a 6-day drip routine of 4 chemicals on a 4 hour rotation, I was told that I had the circulation of a 20 year old. (I was 44 at the time).
This June, I had a nuclear stress test 10 days after diagnosis that resulted in a ‘low normal’ reading. Since that time, I have worked my exercise program up to pre-diagnosis levels. Today, I was on an elliptical machine, level 5, for 90 minutes. My heart rate range was 90 to 124.
My cardiologist explained that collaterals have, in effect, replaced my left Coronary artery. I feel great today and all was well in a follow-up visit with my cardiologist last week.
I really appreciate the articles you have published on this topic. I am 68 years old today and feel like a 30 year old. I plan to continue researching this topic and hope the medical field finds out the potential of collaterals. I have had two major events and have never been operated on. No stents, bypasses, nothing. Maybe more could benefit from this knowledge.
Michael Beirne
Dear Mr.Michael Beirne,
Thank you for comments.
It gives great first hand Information regarding the enigmatic physiology of coronary collateral circulation.Its more Important than sophisticated research in labs.
May I request your permission to post this in my blog and it would be immense help in educating our physicians and patients.
Thanks again

You have my permission to post my history in your blog. I would love to see research aimed at maximizing the potential of collaterals in coronary and other life threatening events.

I was able to learn about Dr Demitrios Sodi Pallares. My father actually met him and learned vector electrocardiology from him. I love your website. Thank you.
Sir,
Nice, decent, helpful very informative blog, found this while I was searching for info on CAG/CT CAG, as my TMT with 13.5mets reported as normal, mild changes after 13.5mets, adviced to go for CT CAG n calcium scoring. What is your advice.
Well done Ma’am! So far from you yet still learning…

Patient in septic shock presented with tachycardia 170 beats per min was not given iv fluids in icu but started inadvertently with hydrocortisone steroid inj 200 mg and then noradrenaline . In 20 mins, patients heart rate came down to 40 beats and plunged to 20. Whats the reason.? Can u explain
Hi.
The web site is wonderful. I learn a lot from it. So I have question for you.
How is it possible a patient with LVEF as low as 15% can do daily activity. I mean l see many patients with this range of ef and their complaints are little.
Thanks for your resonse.

Hi Dr Alireza
Its true what you are observing. It all mean one thing. Circulatory system is not solely dependent on normal cardiac contractility. It adopts. The power of vascular tone and skeletal muscle behaves like a circulatory assist is my explanation. But truth is still a mystery to be solved.
Respected Sir,
I have been following your posts for long and recommended to my friends. They are so informative and concept clearing.
The post titled (great-cardiac-vein-aspiration-for-refractory-lad-no-reflow-a-hypothesis-waiting-for-proof) is causing queries in my mind.
The concept would have worked well had there been some arteriovenous capillary bypassed system. The debris I believe will be stuck at the arteriolar capillary junction. Any suction from the great Cardiac vein may work up-to venules but will collapse the capillaries before it succeed to pull the debris from the arteriolar side of the capillaries. As we know capillaries are nothing but a single cell delicate endothelial layer having a diameter of 5- 8 micrometer.
Thankyou for your comment, Dr Irfan.
I agree with you. The coronary microcirculation is delicate network which may not allow larger particles to cross over.Still its worth a try as it will atleast unclog system to some extent.
Thanks sir
An honour to have a reply from you.

Can you do an article on higher mean gradient (35-40) with bicuspid valve stenosis, but valve size is still mild to moderate at 1.5-2.
Seems most people with 1.5-2 valve size also have much lower mean gradients below 20-25.
Great info and penmanship.
Can you help me to locate the index please?
Hi. Excellent blog you have — which I enjoy! I wanted to use a few of your figures for one of my ECG Blogs (https://ecg-interpretation.blogspot.com/ ) — this would be the 2011 post regarding polymorphic VT. Great illustration of how PMVT may sometimes (often) be from a single focus. I will OF COURSE acknowledge you (and add a specific link to that post in the legend of the figures that I use) — but I wanted your permission to do this. THANK YOU! — Ken Grauer, MD — 🙂
Thanks Dr Ken Grauer for your comments.
You are free to use my posts and Images as you wish.Glad to note it is useful.
