[Diagnostic possibilities using contrast echocardiography].
The contrast echocardiography is based on the occurrence of micro-bubbles in the blood which are stable for a short time and which are passed on the blood stream. These micro-bubbles reflected the ultrasound waves and are represented as contrast echos in the cavities of the heart and the large vessels. They are produced by a bolus injection of saline, glucose, dye (ujoviridin) or the patients' own blood into a peripheral vein or a cavity of the heart. This procedure enables intracardiac insufficiency to be recognized. While the peripheral venous injection is sufficient for differentiating a right-to-left shunt at atrial, ventricular or vascular level, the diagnosis of a left-to-right shunt or of a valvular insufficiency must be made by an injection within a cardiac catheterization. Our results with parasternal and suprasternal transducer position are demonstrated.
