Does leadless pacemaker implantation provide a feasible and low-radiation alternative for bradyarrhythmia-associated syncope in pregnancy?
Leadless pacemaker implantation is a feasible alternative to conventional pacing in pregnant patients, offering reduced radiation exposure and a minimally invasive approach.
Bradyarrhythmias with syncope during pregnancy present a complex and multifaceted challenge for both patients and health care providers. When device implantation is indicated for bradyarrhythmia-associated syncope during pregnancy, the procedure should be performed with particular attention to minimizing fluoroscopy exposure to ensure maternal and fetal safety. A 29-year-old woman at 15 weeks of gestation with sinus pauses presented with recurrent syncopal episodes. The patient underwent Micra™ AV leadless pacemaker implantation (Medtronic, Minneapolis, MN, USA) with a radiation exposure of 26.5 mGy and a total fluoroscopy time of 2 min, which is generally considered a negligible dose during pregnancy, based on the recommendations of the National Council on Radiation Protection and Measurements. In pregnant patients, a leadless pacemaker may offer a viable alternative to conventional pacing, primarily due to its reduced radiation exposure, shorter procedure time, minimally invasive approach, absence of transvenous leads, and lower risk of site infection.
Yokokawa et al. (Sun,) conducted a case report in Sinus pauses and syncope in pregnancy (n=1). Micra™ AV leadless pacemaker was evaluated on Radiation exposure and total fluoroscopy time. Micra AV leadless pacemaker implantation was successfully performed in a pregnant patient with sinus pauses, resulting in a low radiation exposure of 26.5 mGy and 2 minutes of fluoroscopy time.
