3D TEE is a technology developed to improve upon the limitations of 2D tomography. With the introduction of the matrix TEE probe, 3D TEE can collect real-time 3D images that provide a comprehensive view of the heart structures, leading to better understanding and decision making during cardiac procedures.
The fundamental concept of electroanatomic mapping systems is to localize catheters within the heart in three dimensional space (a sort of "GPS" within the heart). Building a 3-D model of the heart with real-time visualization permits reduction in fluoroscopy use. In addition to 3-D structure, the voltage and timing of signals at each point of ...

Echocardiography uses 2D, 3D, and Doppler imaging to create pictures of the heart and visualize the blood flowing through each of the four heart valves. Echocardiography is widely used in an array of patients ranging from those experiencing symptoms, such as shortness of breath or chest pain, to those undergoing cancer treatments.
Finally, images of the heart are taken "at stress" to assess wall motion at the peak heart rate. A stress echo assesses wall motion of the heart; it does not, however, create an image of the coronary arteries directly. Ischemia of one or more coronary arteries could cause a wall motion abnormality, which could indicate coronary artery disease.
The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
