Alteplase Causing Cardiac Tamponade after Recent Cardiac Pacemaker Placement

Area of Science:

• Cardiology
• Neurology
• Emergency Medicine

Background:

• Ischemic stroke treatment often involves thrombolytic therapy, such as alteplase.
• Cardiac tamponade is a serious condition where fluid accumulates in the pericardium, compressing the heart.
• Recent pacemaker placement may alter cardiac anatomy and potentially increase risks associated with invasive procedures or medications.

Observation:

• A 56-year-old female developed cardiac tamponade following alteplase administration for acute ischemic stroke.
• The patient had recently undergone pacemaker implantation, a factor not previously associated with thrombolytic-induced tamponade.

Findings:

• This case represents the first reported instance of cardiac tamponade caused by thrombolytics in a patient with a recent pacemaker.
• Point-of-care ultrasound rapidly diagnosed the evolving cardiac tamponade.
• The patient underwent a successful pericardial window procedure in the operating room.

Implications:

• Highlights a novel complication of alteplase in patients with cardiac devices.
• Emphasizes the importance of considering cardiac tamponade in stroke patients with pacemakers presenting with relevant symptoms post-thrombolysis.
• Demonstrates the critical role of point-of-care ultrasound in the emergency setting for rapid diagnosis and management of life-threatening conditions.
