[Two-dimensional echocardiography in a cardiac intensive care unit].
The increasing number of physicians competent to carry out emergency echocardiography, and the availability of high performance equipment, facilitated the development of this technique in the Coronary Care Unit (CCU). This paper reports our experience of 610 2D echocardiographic recordings performed on 319 patients admitted to the CCU. The quality of the recording was excellent or satisfactory in 67% of cases and mediocre in 30% of cases. In 11 patients (3%) the quality of the recording was too poor to obtain reliable data. In this group of patients, the apical 4-chamber and subcostal views seemed better than the apical 2-chamber and parasternal views. An echocardiographic diagnosis was made in 94% of cases. It contributed to the diagnostic process in 70% of cases. Of the patients studied, 54% were admitted for a recent myocardial infarction. Echocardiography was particularly useful in atypical forms or when the diagnosis was difficult. It was also helpful in detecting complications of recent myocardial infarction, the frequency of which was determined. With respect to other cardiovascular emergencies, echocardiography was determined. With respect to other cardiovascular emergencies, echocardiography was very useful in the diagnosis of dissection of the aorta, pericarditis and for assessing left ventricular function and the causal mechanism in cases of decompensated cardiac failure. The non invasive nature of the investigation allows repeated examination of the patient at the bedside and makes it a particularly valuable technique to monitor the evolution of acute cardiac conditions requiring admission to the Coronary Care Unit.
