Piercing the left lung with a pacemaker lead, an uncommon complication

Area of Science:

• Cardiology
• Medical Devices
• Interventional Procedures

Background:

• Percutaneous insertion of pacemaker leads is a common cardiovascular procedure.
• Despite its general safety, the procedure carries a notable complication rate.
• Complications can range from minor issues to severe, life-threatening events.

Purpose of the Study:

• To report an uncommon and avoidable complication associated with pacemaker lead insertion.
• To highlight the specific risk of lung perforation during the procedure.
• To emphasize the importance of patient factors and technique in preventing adverse events.

Main Methods:

• Case report detailing an instance of pacemaker lead misplacement.
• Focus on a patient with obesity undergoing direct subclavian vein puncture.
• Review of procedural steps and potential points of failure.

Main Results:

• The pacemaker lead inadvertently pierced the lung.
• This complication occurred in the context of direct subclavian vein puncture in an obese patient.
• The event was deemed uncommon and avoidable with careful technique.

Conclusions:

• Lung perforation is a rare but significant risk during percutaneous pacemaker lead insertion.
• Obesity and direct subclavian vein puncture may increase the risk of this complication.
• Adherence to meticulous technique and awareness of patient-specific factors are crucial for prevention.
