ABSTRACT
RATIONALE The use of transvenous pacing leads is associated with the risk of tricuspid valve dysfunction, mainly due to the continuous presence of the leads can have an impact on subsequent tricuspid function and possible operation injury of the tricuspid valve during implantation or operation. PATIENT CONCERNS A 69-year-old female with a history of syncope for 9 months was admitted to the hospital. The electrocardiogram showed sinus bradycardia, junctional escape rhythm, and a heart rate of 44â
bpm. Echocardiography suggested a downward displacement and severe insufficiency of the tricuspid valve and atrial septal defect. DIAGNOSES The cause of syncope was considered to be sick sinus syndrome. The patient was diagnosed with Ebstein anomaly and is considered a candidate for surgical intervention. INTERVENTIONS:
To avoid aggravating tricuspid insufficiency by pacing leads crossing the tricuspid valve and hindering subsequent tricuspid valve surgery, a single-chamber pacing mode with atrial pacing (AAI) lead and Micra AV was chosen for maintaining atrioventricular synchrony after multidisciplinary discussion.OUTCOMES:
The patient had stable parameters and was in good general condition at 1- and 3-month outpatient follow-ups after discharge. LESSONS This is the first case of new implantation of single-chamber atrial pacing + leadless ventricular pacing with Micra AV, an alternative strategy to epicardial or coronary sinus system for tricuspid valve displacement and severe tricuspid regurgitation.
