Acute Traumatic Right to Left Cardiac Shunt

Area of Science:

• Cardiology
• Trauma Surgery
• Thoracic Medicine

Background:

• Penetrating cardiac trauma is uncommon but carries significant mortality risk.
• Early diagnosis can be challenging due to physiological compensation in younger patients.
• Delayed presentation may occur as damage progresses or compensatory mechanisms fail.

Observation:

• A case of unusual penetrating cardiac trauma from a posterior intercostal stab wound is presented.
• The injury involved both the interatrial septum and the tricuspid valve.
• The patient exhibited a stormy clinical course.

Findings:

• The cardiac injury resulted in the development of an acute right-to-left shunt.
• This shunt caused significant physiological disturbance.
• Successful surgical repair of the cardiac defect was achieved.

Implications:

• This case underscores the importance of considering cardiac injury in penetrating chest trauma, even with posterior wounds.
• Early recognition and intervention are crucial for managing potentially life-threatening shunts.
• Successful surgical repair can lead to favorable outcomes in complex cardiac trauma cases.
