I am 49 … not out, how about you TAVI ?
This post was written after coming across a case report  Oxford medical case report.   What is the life of a prosthetic Aortic valve? The standard answer needs to be, mechanical valves can last up to 25  years or more. But, we are in a techno-conflict era.  Instead of working on the longevity of the valve, ( with concerns for long-term OAC )  we fell for the biological valves. Curiously, this has made the durability of the valve, a less relevant discussion in many centers. We get excited when some company brings out a long-lasting bio-prosthetic valve that can live up to a maximum of 15 years. Now, ...

These risks, however, can be managed with the right precautions such as staying hydrated, dressing appropriately, and planning outdoor activities during cooler times of the day. Importantly, each person’s response to heat and medication varies. Hence, a one-size-fits-all approach isn’t ideal. Your healthcare provider is an invaluable resourc...

Reviewing the all-in-pod heart health segment
BY ANISH KOKA The All-in podcast is a fairly popular show that features successful silicon valley investors commenting about everything worth commenting on from politics to health. The group has good chemistry and interesting insights that breaks the mold of the usual tribal politics that controls legacy media analysis of current events. Last week, the podcast touched on a topic I spend a fair amount of time on: Cardiology. Brad Gerstner, who is actually a guest host for this particular episode starts off by referencing something called Heartflow to evaluate the heart that has been recommended by one of the o...

Fight Aging! Newsletter, July 17th 2023
In conclusion, the longevity-associated genotype of FLT1 may confer increased lifespan by protecting against mortality risk posed by hypertension. We suggest that FLT1 expression in individuals with longevity genotype boosts vascular endothelial resilience mechanisms to counteract hypertension-related stress in vital organs and tissues.

Wide complex tachycardia and hypotension in a 50-something with h/o cardiomyopathy -- what is it?
A 50-something male with unspecified history of cardiomyopathy presented in diabetic ketoacidosis (without significant hyperkalemia) with a wide complex tachycardia and hypotension.Bedside echo showed " mildly reduced " LV EF.Here is the ED ECG:What do you think?Analysis: there is a wide complex tachycardia. It is regular.  There are no P-waves.  The morphology is of RBBB and LAFB.  The initial part of the QRS is very fast, suggesting that it starts in conducting fibers and not in myocardium.  Thus, it is probably SVT with aberrancy (RBBB + LAFB) or it is posterior fascicular VT (which starts in the pos...

Ductus Dependent Circulation
Ductus dependent circulation is one in which a patent ductus arteriosus is useful in maintaining the circulation after birth. It is important to rule out such conditions before any PDA closure is planned. PDA dependent circulations can be PDA dependent pulmonary circulation, PDA dependent systemic circulation and PDA dependent mixed circulation. The first group includes pulmonary atresia, tricuspid atresia and tetralogy of Fallot with pulmonary atresia. In those cases, post natal physiological constriction of ductus arteriosus can cause severe hypoxemia, cyanosis and even death. In these cases, there is severe restriction...

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...
