Robotic Catheterization for Mitral Valve Repair: Interview with Mark Barrish, CEO of Moray Medical
At present, mitral heart valve failure is treated through invasive surgery or via a transcatheter procedure called Transcatheter Edge-to-Edge Repair (TEER). However, this procedure is difficult to perform, potentially resulting in suboptimal outcomes in challenging cases and if done by inexperienced clinicians.
To address this, Moray Medical, a company based in Mountain View, California, has developed a robotic catheter and associated technology, including augmented reality and a 3D digital interface, designed to make the job easier. In fact, the company claims that using its technology to deliver cardiac therapies can ...

Rheumatic tricuspid regurgitation
Rheumatic tricuspid regurgitation is almost always associated with mitral valve disease. Organic tricuspid regurgitation is often superimposed on hypertensive tricuspid regurgitation which occurs due to pulmonary arterial hypertension secondary to mitral valve disease. Tricuspid leaflets are thickened and deformed by the rheumatic process which leads to incomplete coaptation and tricuspid regurgitation.
Clinically tricuspid regurgitation is manifest as prominent systolic wave in the jugular venous pulse (cv wave) and a pansystolic murmur in the tricuspid area, increasing on inspiration (Carvallo’s sign). Carvallo’...

Role of RT-PCR in the diagnosis of Rheumatic fever/RHD
RT-PCR: Real-time polymerase chain reaction, a sophisticated gene sequence-based biochemical test. Thanks to corona, this complex medical investigation has become a household name.
Jones proposed his criteria to diagnose acute rheumatic fever in 1944, we still use it to diagnose with many modifications . Currently, AHA position statement – 2015 by Gewitz et all is being followed. (Circulation 2015)
From Braunwald textbook of cardiology. Apart from this, there is one catch . Even if the child fulfills Jone criteria, there needs to be evidence for preceding streptococcal sore throat, either by culture or antibody. ...

Prosthetic heart valves on CXR
Approximate positions of the valves as seen on the CXR are marked in the picture below. A line connecting the pulmonary bay to the right cardiophrenic angle is used to get the positions of aortic and mitral valves. Mitral valve is below this line while aortic valve is above it. Tricuspid valve is a midline structure. But the actual positions may vary from case to case, especially with differential enlargement of the cardiac chambers. Most commonly replaced valves are the mitral and aortic, tricuspid next and pulmonary the least. Annuloplasty rings used for valve repair may also be seen on CXR.
Approximate positions of car...

EchoNous KOSMOS 3-in-1 Ultrasound, Electronic Stethoscope, and ECG Helps with COVID-19
EchoNous, a developer of novel ultrasounds, has found a way to leverage multiple critical clinical technologies within a single device. The result is KOSMOS, a handheld 3-in-1 device consisting of an ultrasound, electronic stethoscope, and an ECG, all linked via artificial technology.
When COVID-19 was hitting NYC earlier this year, EchoNous was able to use KOSMOS to help diagnose COVID patients and to inform on treatment strategies. We had a lovely chat with Dr. Richard Hoppmann, a key member of EchoNous, Clinical Professor of Internal Medicine at the University of South Carolina, and the Director of the Ultrasound I...

Brucellosis – how dangerous is it?
Brucellosis is most frequently transmitted via unpasteurized dairy products
Zoonotic diseases to be keeping the world on its toes. What is the disease responsible for the latest outbreak in China and what is its pathogenic potential?
Not the next COVID-19
Brucellosis is a category B bioterror disease, as classed by CDC. While it is one of the most important zoonotic diseases worldwide, brucellosis has limited pandemic potential, since human-to-human transmission is sporadic and occurs via blood, sexual exposure, or breastfeeding.
63% of cross-border events since 1965 were directly linked to the consumption of unpa...

Exact Models of Aortic Heart Valves Help Prepare for Minimally Invasive Procedures
Complex transcatheter cardiac procedures, such as valve replacements, are often difficult to prepare for. Small anatomical differences can make big impacts on outcomes. Clinicians and researchers have been using models, both virtual and 3D printed, to improve procedural outcomes, design new devices, and to invent new therapeutic techniques. These models generally help professionals to understand nuances between patients, but they don’t reproduce the exact shapes and dynamics of moving tissues and structures.
Now researchers at the University of Minnesota, with help from Medtronic, have developed a way of 3D print...

Synchronising Your Mind: The NeoRhythm Review
In the movie The Matrix, the protagonist, Neo, is able to learn decades worth of kung fu techniques without any prior knowledge of martial arts, simply by plugging his brain into a computer. Within minutes, he utters the famous line: “I know kung fu”.
It’s just a hunch, but the device under review today, the NeoRhythm headband, feels a bit like it was intended to be a real-world version of what Neo experienced. (Notice how they both have Neo in their names? Again, just a hunch). Wear the NeoRhythm and it will help you achieve more through neurostimulation, claims Omnipemf, the company behind the device.

Simplifying Transseptal Access to the Left Atrium: Interview with Terri Burke, CEO of Protaryx Medical
Protaryx Medical, a company based in Baltimore, Maryland, has developed a device to allow for more precise transseptal access to the left atrium during transcatheter procedures. The device provides three-dimensional control and steerability to take the guesswork out of transseptal access to the left atrium, and the company believes that this could improve physician convenience and reduce the chances of complications during such procedures.
Transseptal access to the left atrium is required during several transcatheter procedures, including repair or replacement of mitral valves, catheter ablation therapy, and closure of ...

Fight Aging! Newsletter, July 20th 2020
This study was the first to demonstrate a causal relationship between glial senescence and neurodegeneration. In this study, accumulations of senescent astrocytes and microglia were found in tau-associated neurodegenerative disease model mice. Elimination of these senescent cells via a genetic approach can reduce tau deposition and prevent the degeneration of cortical and hippocampal neurons.
Most recently, it was shown that clearance of senescent oligodendrocyte progenitor cells in AD model mice with senolytic agents could lessen the Aβ plaque load, reduce neuroinflammation, and ameliorate cognitive deficits. This...

Gender differences in cardiovascular disease: Women are less likely to be prescribed certain heart medications
Cardiovascular disease (CVD) is the leading killer of both women and men in the US. Despite the significant impact CVD has on women, awareness and education for women’s heart disease has historically been low. A recent study, based on data from over two million patients, suggests that women were less likely to be prescribed aspirin, statins, and certain blood pressure medications compared to men.
CVD is a group of diseases involving the heart or blood vessels. It includes high blood pressure (hypertension), coronary artery disease, heart attacks, heart failure, heart valve problems, and abnormal heart rhythms. CVD ca...

Shear Stress in the Aging Heart Makes Immune Cells Inflammatory, Accelerating Cardiovascular Disease
Researchers here note a process by which the hardening of heart valves, known as aortic valve stenosis, accelerates in its later stages. The condition causes greater shear stress in blood flow, which in turn causes immune cells in the bloodstream to become more inflammatory. The resulting greater chronic inflammation in heart tissue accelerates the mechanisms that cause stenosis. This hardening of tissue is due to calcification; a growing fraction of cells in the valves adopt behaviors more appropriate to bone tissue, creating calcium structures. Inflammatory signaling, such as that produced by the presence of senescent ce...
