What is Fontan Paradox?
The term Fontan Paradox was coined by Marc de Leval in 2005 as paradox seen in Fontan circulation with caval hypertension, mainly in the splanchnic region and relative pulmonary arterial hypotension [1,2]. According to him, in a normal biventricular circulation, the mean caval pressures are less than 10 mm Hg and the mean pulmonary arterial pressure is at least 15 mm Hg to keep the pulmonary vasculature patent. He further suggested that a mechanical device capable of producing a step down in pressure energy of 5 mm Hg in the inferior vena cava and producing a step up of 5 mm Hg in the pulmonary arteries could potentially ...

Oral Estrogen Linked To High Blood Pressure Risk: An In-depth Study Analysis
Conclusion As a whole, this study indicates a strong correlation between the method of estrogen administration and the risk of hypertension. Oral estrogen seems to carry a higher risk compared to transdermal patches and vaginal creams. The duration and dosage of estrogen consumption are also significant factors. Remember, regular self-monitoring is critical, and for that, we provide valuable guides on our website for things like ‘how to lower blood pressure’ and ‘checking blood pressure at home’.

Cath lab nightmares : Beware, this one has no simple cure !
Cath lab nightmares may be a cliche word for all of us. Still, It has become a mandatory topic in any cardiology conferences and live workshops. These sessions are always popular and crowded as Interventional cardiologists are eager to get tips from other experts,  on what to and what not to do in the cath lab in crisis situations. While stuck in an unexpected problem, these tips really help us come out of this, with shared expertise, presence of mind, skills, innovation, etc.  I used to wonder, what the word nightmare really mean. Thesaurus helped to find it. Nightmare: A Terrifying feeling due to some untoward event ...

When ” Cath lab viability ” competes with myocardial viablity … Just carry on !
Pure science Whenever possible ,before doing a coronary revascularisation procedure , check twice the segments you try to perfuse is really short of blood supply and truly needs the procedure. Don’t ever waste your resources and try to blood-feed the dead myocardium. It’ can never be awakened ! Pragmatic science I was conversing with my colleague recently , who has grown into  suave , Interventional cardiologist with a huge academic & societal repute .He owns a personal cathlab and planning to get one more. I learnt a non-academic reality lesson from him . When planning myocardial revasascularisation, ...

75 year old with 24 hours of chest pain, STEMI negative
Written by Jesse McLaren A 75 year old with a history of CABG called EMS after 24 hours of chest pain. HR 40, BP 135/70, RR16, O2 100%. Here ’s the paramedic ECG (digitized by PMcardio). What do you think? There ’s sinus bradycardia, normal conduction, normal axis, delayed R wave progression, and normal voltages. There are inferior Q waves and lead III has mild concave ST elevation, with subtle reciprocal ST depression in I/aVL. This is diagnostic of inferior OMI, likely from the RCA. The patient has a hi story of CABG so some of these changes could be old, but with ongoing chest pain and bradycardia in a hig...

The Current State of 521 FDA-Approved, AI-Based Medical Devices
The rise of Artificial Intelligence (AI) and Machine Learning (ML) in healthcare has reshaped the industry. And due to the recent march of ChatGPT, Midjourney and similar tools, various AI algorithms have entered the lives of the general population as well. These technologies will undoubtedly change the way medicine is practiced. Given that healthcare is an industry where decisions can literally be a matter of life and death, the importance of effective regulation can’t be overstated. Now this is one hell of a challenge even for the most seasoned professionals. AI and ML present novel regulatory challenges. Unlike...

COAPT Trial of Transcatheter Mitral Valve Repair in Patients with Heart Failure
Patients with heart failure and left ventricular dilatation may have secondary or functional mitral regurgitation. This is due to alteration of the left ventricular geometry producing changes in the functioning of papillary muscles and chordae tendineae and poor coaptation of the mitral leaflets. Secondary mitral regurgitation causes volume overloading of the left ventricle and is associated with reduced survival, increased hospitalization rates and decreased quality of life [1, 2]. Secondary mitral regurgitation can be reduced by guideline directed medical therapy and cardiac resynchronization therapy. This will also pro...

A 40-something male with resolving chest pain and a " Normal ECG " by computer and cardiology overread
A 40-something male presented by ambulance with one hour of chest pain that was improving after sublingual nitroglycerine and 325 mg of aspirin, chewed.  Here is his initial ED ECG:What do you think?I read this ECG without any history as reperfusing inferior and posterior OMI due to the Q-wave in lead III with minimal STE and reciprocal ST depression in V2-V4 (which should never be there).  The large upright T-wave in V2 is consistent with reperfusion.Any ST Depression Maximal in V1-V4 is OMI until proven otherwiseI sent this ECG with no information to Pendell.  We send each other EKG by the dozens...

Myocardial Insulin Resistance
Myocardial insulin resistance is said to occur in about 60% of patients with type 2 diabestes mellitus and is associated with higher cardiovascular risk compared to those with insulin sensitive myocardium [1]. It is  known that systemic insulin resistance is an independent risk factor for heart failure and cardiovascular death [2]. Myocardial insulin resistance occuring along with systemic insulin resistance is characterized by ineffecient energy metabolism and contributes to post ischemic heart failure. Myocardial insulin resistance can also be caused by myocardial hypertrophy, independent of systemic insulin resist...
