Summary
Leadless pacemakers (LPs) offer an alternative to transvenous devices for bradycardia and AV conduction disorders. The Micra AV (MAV) system enhances LP therapy with advanced AV synchronicity and unique programming options.
Area of Science:
- Cardiology
- Biomedical Engineering
- Medical Devices
Background:
- Leadless pacemakers (LPs) are increasingly used for bradycardia and atrioventricular (AV) conduction disorders.
- While LPs offer benefits, concerns regarding their application and efficacy persist.
- Advancements in leadless technology are crucial for improving patient outcomes.
Approach:
- This review focuses on the Micra AV (MAV) leadless pacemaker.
- It examines key clinical trials evaluating MAV performance.
- The review details the principles of AV synchronicity achieved with MAV.
Key Points:
- The Micra AV (MAV) system provides atrial-ventricular (AV) synchrony, a significant advancement in leadless pacing.
- MARVEL trials demonstrated the efficacy of AV synchronization in leadless pacemakers.
- MAV offers unique programming features to optimize AV synchronicity.
Conclusions:
- Leadless pacemakers, particularly the Micra AV, represent a significant evolution in cardiac pacing.
- Achieving AV synchronicity with leadless technology improves therapeutic options for bradycardia and AV conduction disorders.
- Further understanding of MAV's programming capabilities is essential for maximizing its clinical benefits.

Bradyarrhythmias are cardiac rhythm disorders characterized by a slower-than-normal heart rate, typically defined as fewer than 60 beats per minute. Some of which are discussed here:Sinus BradycardiaSinus bradycardia presents a heart rate lower than 60 beats per minute, with a regular rhythm originating from the SA node. The ECG typically shows normal P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and a normal QRS duration (0.06 to 0.10 seconds).First-Degree AV...

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...
