Real-time, two-dimensional echocardiographic features of pacemaker perforation

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Myocardial perforation is a rare but serious complication of temporary transvenous pacemaker placement.
• Accurate and timely diagnosis is crucial for patient management and preventing further complications.

Purpose of the Study:

• To evaluate the utility of real-time, two-dimensional echocardiography in diagnosing myocardial perforation by temporary transvenous pacemaker catheters.
• To assess the role of echocardiography in guiding catheter repositioning or removal.

Main Methods:

• Real-time, two-dimensional echocardiography was performed on five patients with suspected pacemaker-induced myocardial perforation.
• Echocardiographic findings were correlated with clinical presentation, procedural outcomes, and autopsy results where available.

Main Results:

• Echocardiography identified catheter perforation through the right ventricular wall in three patients and the atrioventricular septum in one patient.
• Partial ventricular septal penetration was noted in another patient.
• Pericardial effusion was visualized in two patients; echocardiography guided successful catheter withdrawal in four patients.

Conclusions:

• Real-time, two-dimensional echocardiography is a valuable tool for diagnosing pacemaker-related myocardial perforation.
• Echocardiography facilitates visualization of catheter position, aids in management decisions, and can guide safe catheter removal.
