[Focused cardiac ultrasound in internal medicine]

Focused cardiac ultrasound is a noninvasive technique which can be performed by the internist. It is capable of providing useful, rapid and accurate information about the structure and function of the heart. It can be used to complement anamnesis and physical examination at the bedside. Clinicians may be able to determine left and right ventricular diameter and function, detect the presence of significant pericardial effusion, identify important valvular defects and estimate the central venous pressure by measuring the diameter and collapsibility of inferior vena cava with good accuracy after a short training period. The aim of focused cardiac ultrasound is not to perform a complete echocardiogram but using previous mentioned data, it is possible to expedite diagnosis and optimize the management of patients with cardiovascular diseases.
