Cardiac Standstill With Intracardiac Clot Formation

Area of Science:

• Cardiology
• Emergency Medicine
• Medical Imaging

Background:

• Cardiac arrest is a critical medical emergency requiring immediate intervention.
• Prolonged no-flow states can lead to severe cardiovascular complications.
• Echocardiography is a vital tool in assessing cardiac function during resuscitation.

Purpose of the Study:

• To describe and illustrate cardiac standstill with thrombosed blood in a cardiac arrest case.
• To correlate ultrasound findings with the decision to terminate resuscitation.

Main Methods:

• Case report detailing a patient in cardiac arrest.
• Intracardiac ultrasound imaging to assess cardiac chambers and blood flow.
• Clinical decision-making based on ultrasound findings.

Main Results:

• Ultrasound revealed cardiac standstill with evidence of thrombosed blood within the heart chambers.
• The findings suggested significant blood stasis due to a prolonged no-flow state.
• These echocardiographic results informed the decision to halt resuscitative efforts.

Conclusions:

• Intracardiac ultrasound can identify severe cardiac pathology, such as thrombosis secondary to stasis.
• Ultrasound findings of cardiac standstill and thrombosis can be a factor in determining the futility of resuscitation in cardiac arrest.
• This case highlights the utility of point-of-care ultrasound in critical care decision-making.
