Cardiac evaluation following heart injury

Area of Science:

• Cardiology
• Trauma Surgery
• Diagnostic Imaging

Background:

• Penetrating and blunt cardiac injuries necessitate prompt medical intervention.
• Survivors of cardiac trauma face significant risks of delayed complications, often requiring further surgical procedures.

Purpose of the Study:

• To evaluate the efficacy of diagnostic imaging techniques in identifying residual injuries after initial management of cardiac trauma.
• To determine the role of two-dimensional echocardiography (2-D echo) and pulsed-Doppler in conjunction with cardiac catheterization for assessing heart injury sequelae.

Main Methods:

• Retrospective analysis of 204 patients with heart injuries from January 1980 to June 1984.
• Echocardiography (2-D and pulsed-Doppler) and/or cardiac catheterization performed on 40 survivors with suspected residual injuries.
• Detailed review of imaging findings, including pericardial effusion, chamber abnormalities, and intracardiac findings.

Main Results:

• Eight out of 40 patients with suspected residual injuries required secondary cardiac operations.
• 2-D echo identified pericardial effusion, chamber enlargement, wall motion abnormalities, intracardiac missiles, and thrombi.
• Pulsed-Doppler revealed ventricular septal defects, tricuspid insufficiency, and arteriovenous fistulae; cardiac catheterization detected a lesion missed by 2-D echo in one case.

Conclusions:

• Two-dimensional echocardiography with pulsed-Doppler serves as an excellent initial screening method for cardiac injuries when bullets are not apparent on chest X-ray.
• Cardiac catheterization is indicated for selected patients with positive echocardiogram findings or when bullets are visible on imaging, suggesting potential residual cardiac damage.
