Echocardiographic evaluation after blunt trauma of the chest.
We studied by cross-sectional echocardiography 27 consecutive subjects with severe blunt trauma of the chest. Inadequate studies were obtained in 6 subjects (22%). Abnormal, unexpected findings were noted in 6 of the remaining 21 subjects (29%): moderate size pericardial effusion in 3 and focal ventricular dysfunction in 4. No patient with echocardiographic abnormality was suspected clinically of having heart damage. One of the 6 subjects with abnormal echocardiographic findings died from sudden asystole 6 days later. The remaining 5 patients had normal echocardiographic findings when studied 1 week after trauma. This study shows that, following blunt chest trauma, cross-sectional echocardiography can detect unsuspected myocardial and pericardial damage in an appreciable number of patients. Ultrasonic examination of the heart complements other investigations in establishing the diagnosis of heart damage and may help improve the care of patients with heart trauma.
