2-D (two-dimensional) echocardiography: This technique is used to “see” the actual motion of the heart structures. A 2-D echo view appears cone-shaped on the monitor, and the real-time motion of the heart’s structures can be observed. This enables the doctor to see the various heart structures at work and evaluate them.
An echocardiogram is a noninvasive (the skin is not pierced) procedure used to assess the heart’s function and structures. During the procedure, a transducer (like a microphone) sends out sound waves at a frequency too high to be heard. When the transducer is placed on the chest at certain locations and angles, the sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or “echo” off of the heart structures. These sound waves are sent to a computer that can create moving images of the heart walls and valves.
