Background And Aims: Prior reports have demonstrated a favourable safety and efficacy profile of the Micra leadless pacemaker over mid-term follow-up; however, long-term outcomes in real-world clinical practice remain unknown. Updated performance of the Micra VR leadless pacemaker through five years from the worldwide post-approval registry (PAR) was assessed.
Methods: All Micra PAR patients undergoing implant attempts were included.
We present the case of a 42 year old patient with a history of childhood lymphoma treated with chemotherapy and radiation who underwent combined aortic and mitral valve replacements and who postoperatively developed an interesting ECG which showed complete heart block and an alternating left bundle branch and narrow complex QRS pattern at a heart rate of 69 beats per minute (bpm). We discuss potential mechanisms for this interesting pattern.

The ECG Belt system (EBS) is a novel surface mapping system designed to measure electrical dyssynchrony via the standard deviation of the activation times of the left ventricle.
Objectives: The objectives of this study were to evaluate the efficacy of the EBS in patients less likely to respond to CRT and to determine whether EBS use in lead placement guidance and device programming was superior to standard CRT care.
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.
There have been no recent descriptions of the spontaneous conversion of long-standing atrial fibrillation (AF) or flutter (AFl) to sinus rhythm which, in the past, has been associated with rheumatic mitral valve disease and treatment with digoxin. We present 3 contemporary cases, all of whom progressed from AF to slow AFl and then spontaneously converted to slow sinus or junctional rhythm. None of these patients had rheumatic heart disease or were treated with digoxin.

Although abandonment of the TPS at end of life is recommended, certain situations such as endovascular infection or device embolization warrant retrieval.
Objective: The purpose of this study was to report the worldwide experience with successful retrieval of the Micra TPS.
Background: Early experience with leadless pacemakers has shown a low rate of complications. However, little is known about system revision in patients with these devices.
Objective: The purpose of this study was to describe the system revision experience with the Micra Transcatheter Pacing System (TPS).
