High resolution map of aortic root tachycardia

A 63-year-old woman without structural heart disease was referred with frequent, sustained episodes of atrial tachycardia. The episodes had terminated spontaneously before vagal manoeuvres or acute pharmacological intervention could be tried. Tachycardia with a cycle length 390 –420 ms was induced. High-density electroanatomic mapping using the Carto mapping system and a pentaray mapping catheter revealed earliest right atrial activation close to the His bundle. The earliest left atrial activation was in an adjacent position at similar timing, but mapping in the aortic root revealed earlier activation than obtained endocardially in either atrium (Panel A). In the non-coronary sinus of Valsalva, low-amplitude atrial electrograms preceded any other electrogram by 20  ms (Panel B). Radiofrequency delivery at this site terminated the tachycardia, resulting in non-inducibility and clinical resolution.

In this study, we investigated the effects of these granules on myocardial fibrosis in a rat model of myocardial infarction in vivo. Methods: Male Wistar rats were randomly divided into four groups: the sham operation group, the acute myocardial infarction (AMI) group, the Luhong granule group, and the vancomycin group, with a sample size (n) of 10 rats in each group. The AMI model was established in all rats by ligation of the left anterior descending (LAD) coronary artery (the sham operation group did not undergo ligation). Luhong granules (0.5 ml·kg-1·d-1), vancomycin (0.075 g·ml-1...

(CNN/CBS) — At least 1,300 people have died from the flu so far this season, according to a preliminary estimate released Friday by the US Centers for Disease Control and Prevention. There have been at least 2.6 million flu illnesses and 23,000 flu-related hospitalizations, according to the analysis. So far this season, the CDC has received reports of 10 children who have died from the flu, four more than the week before. Experts have warned that flu is hitting the United States early this year, and there are concerns that this early season could mean a particularly severe season overall. Flu spread significantly in ...

Conclusion: The term neonates with RD have an increase in plasma NT-pro BNP. NT-pro BNP is a very good useful test for identification of CHD in neonates with RD, in comparison to PD. Therefore, plasma NT- pro BNP can be used to differentiate between cardiac and pulmonary cause of RD.

Authors: Sbeit W, Kadah A, Mari A, Mahamid M, Khoury T Abstract Background: Percutaneous endoscopic gastrostomy (PEG) tube insertion is an increasingly used minimally invasive method for long-term enteral feeding. Identification of simple predictors for short-term mortality (up to one month) after PEG insertion is of paramount importance. Aim: We aimed to explore a simple noninvasive parameter that would predict survival following PEG insertion. Methods: We performed a retrospective study of all patients who underwent PEG insertion at the Galilee Medical Center from January 1, 2014 to December 30, 2018. We ...

Right now, one in 12 children and adolescents in the US are severely obese. If that isn’t startling enough, consider this: among 12-to-15-year-olds, that number jumps to one in 10 — and among 16-to-19-year-olds, it is one in seven. According to the American Academy of Pediatrics (AAP), the best hope for many of these youths may be bariatric surgery. Bariatric surgery is surgery that helps with weight loss by making the stomach smaller and making other changes in the digestive system. It’s jarring to think about doing irreversible surgery on an adolescent — or a child, as the AAP discourages age limi...
