Medical Question
What will happen in 12 months to a patient 71 years old with an Aveir VR, a single-chamber ventricular leadless pacemaker that does not sense or pace the atrium, so it cannot actively preserve AV synchrony?
Medical Analysis
For a 71-year-old patient with a single-chamber ventricular leadless pacemaker (Aveir VR) that does not sense or pace the atrium, the 12-month outlook depends on several factors:
Expected Outcomes:
- Pacemaker Syndrome: The patient may experience pacemaker syndrome symptoms due to loss of AV synchrony, including fatigue, exercise intolerance, palpitations, or shortness of breath
- Ventricular Function: The right ventricle will be paced, which could potentially lead to ventricular dyssynchrony over time
- Underlying Rhythm: The outcome heavily depends on the patient's underlying cardiac condition and native rhythm
- Device Function: The Aveir VR device itself will likely continue to function properly with stable battery life
Clinical Management:
Regular follow-up will be essential to monitor for symptoms of pacemaker syndrome and potentially adjust medications. The medical team may need to optimize the pacing rate and settings to minimize adverse effects.
Risk Factors:
Patients with pre-existing diastolic dysfunction or who are pacemaker-dependent are more likely to experience adverse effects from the loss of AV synchrony.
