Article Synopsis
- The Micra AV is a new type of transcatheter pacing system that achieves synchronous pacing by sensing mechanical contractions of the atrium, using advanced programming features like A3 and A4 windows.
- It’s essential for electrophysiologists to have in-depth knowledge of these programming parameters to enhance AV synchrony and address variability in patient outcomes.
- An expert panel of European electrophysiologists recommends specific programming approaches based on patient profiles, including evaluating atrial activity via echocardiography before implantation and customizing settings for optimal performance in different types of AV blocks.
Article Synopsis
- Early results from Micra trials indicate strong safety and performance, but the impact of anticoagulation status during implant hasn't been thoroughly studied.
- The study aimed to evaluate implant characteristics and complications based on patients' anticoagulation strategies (none, interrupted, or continued) during the Micra device implantation.
- Findings showed that patients without anticoagulation were generally younger and had different medical histories; however, the implant success rate was high across all groups, and complications did not significantly vary with the anticoagulation strategy, implying Micra's safety in all cases.
Purpose: To retrospectively compare the kinetic magnetic resonance (MR) imaging characteristics of invasive breast carcinomas with both prognostic tumoral and patient-related parameters.
Materials And Methods: This HIPAA-compliant retrospective study was approved by the institutional review board, and informed consent was waived. From January 2008 to January 2011, 273 consecutive women (mean age, 55 years; range, 23-83 years) with invasive breast cancers who had undergone MR imaging were selected.
