Dobutamine Stress Echocardiography for the Bedside Assessment of Viability Following a Motor Vehicle Accident and Subsequent Myocardial Infarction: A Case Report.

The authors describe a case of a critically ill patient presenting after motor vehicle trauma complicated by anterior myocardial infarction and cardiogenic shock. Assessment of myocardial viability in the territory of a critically stenosed left anterior descending artery (LAD) was necessary to determine the optimal management strategy. Bedside dobutamine stress echocardiography (DSE) demonstrated viability in the LAD territory and the patient underwent uncomplicated single-vessel bypass surgery with subsequent improvement in left-ventricular function. This case illustrates the utility of bedside DSE to assess myocardial viability in patients for whom other non-invasive modalities are not feasible.
