Delayed complications following pacemaker implantation

Area of Science:

• Cardiology
• Medical Devices
• Cardiac Surgery

Background:

• Permanent pacemaker implantation is a common procedure for managing bradyarrhythmias.
• While acute complications are recognized, late complications can also arise.
• Perforation and pericarditis are significant late complications following pacemaker implantation.

Observation:

• This report details five cases of late cardiac perforation caused by active-fixation pacemaker leads.
• These events occurred days to weeks after initial pacemaker implantation.
• Patients presented with symptoms such as chest pain, necessitating prompt medical evaluation.

Findings:

• Late perforation of the right atrium or ventricle, though uncommon, is a critical complication.
• Active-fixation leads were implicated in the reported cases of delayed perforation.
• The time frame for these late complications ranged from a week to several months post-implantation.

Implications:

• Cardiologists must maintain a high index of suspicion for late perforation in patients presenting with chest pain after pacemaker implantation.
• Prompt diagnosis and management are vital to prevent potentially fatal outcomes.
• This highlights the importance of long-term device monitoring and patient follow-up.
