Unexpected Silicone Breast Implant Rupture After Implantation of Insertable Loop Recorder

Area of Science:

• Cardiology
• Medical Devices
• Surgical Complications

Background:

• Insertable loop recorders (ILRs) are subcutaneous cardiac monitoring devices used for diagnosing unexplained palpitations and syncope.
• ILR implantation is generally considered safe with rare complications.
• Breast implants are common, and their potential interactions with implanted medical devices require consideration.

Observation:

• A patient developed subacute breast implant rupture after the placement of an insertable loop recorder.
• The ILR was implanted in the left parasternal region, adjacent to the breast implant.
• The rupture was characterized as subacute, developing over a period after the initial implantation.

Findings:

• This case represents a previously unreported complication of ILR insertion.
• The proximity of the ILR to the breast implant is implicated in the device-induced rupture.
• The subacute nature of the rupture suggests a delayed inflammatory or mechanical process.

Implications:

• Clinicians should be aware of this rare potential complication when considering ILR placement in patients with breast implants.
• Further investigation may be warranted to understand the mechanism and incidence of this complication.
• This finding highlights the importance of considering anatomical proximity and potential device interactions in implantable cardiac electronic device procedures.
