Extraction of a Micra Transcatheter Pacing System: First-in-human experience

Clinical trials investigating the safety and effectiveness of transcatheter leadless pacemakers in humans are ongoing. These devices offer the benefits of cardiac pacing with the potential for a significant decrease in many of the risks associated with conventional pacing systems, including hematoma formation, pneumothorax, lead-related complications, and vascular obstruction. Human evaluation ...

Beyond MICRA: New Ideas for Liability Reform

The circular RNA MICRA for risk stratification after myocardial infarction☆

Background A significant proportion of patients develop heart failure (HF) after acute myocardial infarction (MI). Predicting this development with novel biomarkers would allow tailoring healthcare to each individual. We recently identified a circular RNA called MICRA which was associated with HF development after MI. Here, we tested whether MICRA was able to risk stratify MI patients. Method...

Parvimonas micra enhance gingpain activity in multi-species consortia

Dental biofilms are complex and consists of many different species which can interact with each other and affect virulence properties. In this study we investigated the effect of Parvimonas micra on proteolytic activity in a multi-species bacterial consortium. Multispecies consortia were constructed, with and without P. micra, using the following species: Porphyromonas gingivalis, Prevotella in...

Retrieval of Medtronic Micra Transcatheter Pacing System after tether removal.

We implanted a Medtronic Micra Transcatheter Pacing System (TPS) using standard technique, but after cutting the tether, a slight resistance was felt when the tether was pulled back. Subsequently, the electrical properties of the system were unacceptable. In order to retrieve the TPS, a 3 F snare with a 10–25 mm loop can be loaded into the delivery system. However, this snare was not available....
