TIGERTRIEVER 13, World ’s Smallest Clot Retriever for Strokes, Cleared in Europe
Rapid Medical, based in Yokneam, Israel, won European regulatory approval to introduce its TIGERTRIEVER 13, the narrowest clot retriever now available for use in treating ischemic stroke. The device can be used in vessels as small as 1 millimeter in width and up to a maximum of 2.5 mm, where larger retrievers would be appropriate. It works through a microcatheter that has an outside diameter of 1.3 French, getting into brain vasculature previously impossible to access.
Unlike many existing devices, the entire TIGERTRIEVER is visible under fluoroscopy. It does feature radiopaque markers that make positioning and measure...

EMBOTRAP II Clot Retriever Now Saving People from Ischemic Strokes in U.S.
CERENOVUS, a part of Johnson & Johnson, is reporting that its EMBOTRAP II clot retriever has been used commercially for the first time in the U.S. to reverse an ischemic stroke.
The catheter-delivered device is able to securely grab onto the clot without squeezing it too hard, allowing the physician to manipulate the thrombus as a whole. This can prevent downstream damage if chunks of the clot come off the main piece.
The device is intended to be used within eight hours of initial stroke symptoms.
Some recent results of a study evaluating the effectiveness of the EMBOTRAP II, according to CERENOVUS:
In the ARISE II (...

Is Medical Imaging a Ricardian ” Derived Demand ” ?
By SAURABH JHA
Medical Imaging and the Price of Corn
After the Napoleonic wars, the price of corn in England became unaffordable. The landowners were blamed for the high price, which some believed was a result of the unreasonably high rents for farm land. Economist David Ricardo disagreed.
According to Ricardo, detractors had the directionality wrong. It was the scarcity of corn (the high demand relative to its supply) that induced demand for the most fertile land. That is, the rent did not increase the price of corn. The demand for corn raised the rent. Rent was a derived demand.
Directionality is important. Getting direc...

How dangerous are NSAIDs in patients with AF?
One of the most commonly asked questions in the office is the treatment of arthritis pain. This comes up because of the concern over taking NSAIDs (non steroidal anti-inflammatory drugs) in patients who are on anticoagulants (such as warfarin, or dabigatran, rivaroxaban, apixaban).
My views on this matter have changed.
But first, I want to mention a study published in JACC that addressed the issue of NSAID use in pts with AF who take an anticoagulant.
This was a sub-analysis of the RELY trial, which pitted dabigatran vs warfarin. Remember, in the original RELY trial, the 150mg dose of dabigatran did better than warfarin at...

The Evidence Crisis: Causal Inference – Don ’ t be a chicken (Part 3)
By ANISH KOKA
Part 1
Part 2
Physicians have been making up numbers longer than people have been guessing weights at carnivals. How much does this statin lower the chances of a heart attack? How long do I have to live if I don’t get the aortic valve surgery?
In clinics across the land confident answers emerge from doctors in white coats. Most of the answers are guesses based on whatever evidence about the matter exists applied to the patient sitting in the room. The trouble is that the evidence base used to be the provenance of experts and anecdotes that have in the past concluded leeches were good for pneumonia...

As CABANA waves a final good bye to catheters in AF . . . let the pulmonary veins rejoice !
There is a tough ongoing rivalry between drugs and catheters to conquer the commonest electrical chaos in human heart, namely Atrial fibrillation (AF). Mind you,the confusion about the importance of this arrhythmia is huge and real.Bulk of these episodes are transient , paroxysmal and do not require rigorous management.While stroke prevention seems to be the major aim and target , the real world scenario seems to tell a different story.
The nomenclature conundrum
AF may be classified as many ways a learned cardiologists can think . Often it’s done with reference to etiology, duration , rate, neural (sympathetic o...

Heart disease in pregnancy: Risk stratification
It is needless to say that heart disease in pregnancy is a challenge for the obstetrician and the cardiologist. Hemodynamic changes in pregnancy and labour can adversely affect many of the significant cardiac lesions. Increase in blood volume and heart rate are the important factors during pregnancy. In general stenotic lesions and pulmonary hypertension are poorly tolerated, while regurgitant lesions are better tolerated. Specific risks like aortic dissection and rupture are there for coarctation of aorta. Several risk stratification schemes have been developed for assessing the risk of pregnancy with heart disease over ...

EMBOTRAP II Pulls Clots from Brain With Minimal Compression: FDA Cleared
CERENOVUS, a Johnson & Johnson company that was built by combining Pulsar Vascular, Neuravi, and Codman Neuro’s neurological business, won FDA clearance for the EMBOTRAP II Revascularization Device. The stent retriever is used to pull blood clots from the brain, restoring blood flow and hopefully preventing the terrible consequences of a stroke.
The device, intended to be used within eight hours of initial stroke symptoms, is designed to apply as little pressure on the clot as possible in an attempt to avoid breaking it up into smaller parts, while confidently grabbing it to make sure it is removed completely.

Fight Aging! Newsletter, April 23rd 2018
In conclusion, a debate exists on whether aging is a disease in itself. Some authors suggest that physiological aging (or senescence) is not really distinguishable from pathology, while others argue that aging is different from age-related diseases and other pathologies. It is interesting to stress that the answer to this question has important theoretical and practical consequences, taking into account that various strategies capable of setting back the aging clock are emerging. The most relevant consequence is that, if we agree that aging is equal to disease, all human beings have to be considered as patients to be treat...

Delivery of Exosomes Improves Recovery from Stroke in Pigs
This study, coupled with our previously published studies focused on a mouse model, represents the first time that a company demonstrated proof-of-concept of the therapeutic potential of extracellular vesicles in two divergent animal species and two stroke types - embolic and ischemic." This is the third study recently completed by ArunA, the first two of which demonstrated improved outcomes in middle-aged and aged mice following embolic stroke.
Study results showed NSC EV treatment: was neuroprotective; eliminated intracranial hemorrhage in ischemic lesions; improved behavior and mobility; decreased cerebral infarc...
