title: [Emergency ultrasound cardiography in acute precordial pain of cardiovascular origin].
abstract: In emergency surgery, the essential prerequisites for success are speed, promptitude and precision. For this reason diagnosis must be equally prompt and precise and may require not only clinical examination but also a number of instrumental examinations designed to confirm or even to formulate the diagnosis which is usually the case in precordialgias of cardiovascular origin. In such syndromes ultrasound cardiography is particularly advantageous for the following reasons: it is non-invasive, provides immediate results and any number of examinations can be performed on the patient in bed. Since such ultrasound techniques are also reliably accurate, they constitute the method of choice when the patient's condition is critical, when a serial study of a single patient is required and when the results are required immediately, as is the case in emergency heart surgery. Four types of ultrasound cardiography are currently available for the diagnosis of precordialgias of cardiovascular origin: 1) one dimensional M-mode echocardiography; 2) two dimensional real time echocardiography; 3) Doppler ultrasound cardiography; 4) the echo-Doppler system in which Doppler ultrasound cardiography is combined with one or two dimensional echocardiography. Acute precordial pain of cardiovascular origin may be due to the following pathological conditions: 1) ischaemic cardiopathy especially acute myocardial infarction and transitory myocardial ischaemia; 2) acute pericarditis; 3) aortic stenosis; 4) idiopathic hypertrophic subaortic stenosis; 5) mitral prolapse; 6) dissecting aneurysm of the aorta; 7) pulmonary thromboembolism. In all these cases the single and two dimensional image and Doppler ultrasound cardiography provide highly sensitive and specific information that is, in some cases, decisive for diagnosis and in others confirms the diagnosis already formulated. In addition these techniques may provide valuable prognostic data. Ultrasound cardiography is indeed useful in all cardiological emergencies, such as those caused by cardiomegaly, new and developing murmurs, peripheral embolisms, cardiac traumas and arrhythmias. It is therefore suggested that every Emergency and Intensive Care Unit should be able to use the resources offered by ultrasound cardiography in diagnosis.
