Visualization of traumatic tricuspid insufficiency by three-dimensional echocardiography

Area of Science:

• Cardiology
• Trauma Surgery
• Medical Imaging

Background:

• Blunt chest trauma from motor vehicle accidents can cause cardiac injuries.
• Tricuspid insufficiency is a potential complication requiring accurate diagnosis.
• Echocardiography is crucial for evaluating valvular heart disease.

Observation:

• A 19-year-old male presented with a holosystolic murmur post-trauma.
• Initial transthoracic echocardiography indicated severe tricuspid insufficiency of unclear etiology.
• Three-dimensional echocardiography identified flail leaflets of the tricuspid valve.

Findings:

• The patient was diagnosed with tricuspid insufficiency secondary to papillary muscle rupture caused by chest blunt trauma.
• Surgical repair of the tricuspid valve was successfully performed.
• Post-operative recovery showed relief from right ventricular heart failure symptoms.

Implications:

• Three-dimensional echocardiography is highly valuable for assessing complex tricuspid valve and papillary muscle damage.
• Prompt diagnosis and surgical intervention can effectively manage traumatic tricuspid insufficiency.
• This case highlights the utility of advanced imaging in trauma-related cardiac injuries.
