Translation Video 1. Animation 2. Rotation Animiation Video 2. Rotation Video Torsion is the wringing motion that the heart exibits where the base will twist less than the apex of the heart. When imaging a myocardial wall from base to apex, the base will rotate less through the imaging plane whereas the apical wall will have more rotation. Animation 3. Torsion Animation Video 3. Torsion Video Interpreting myocardial motion, where excessive cardiac motion occurs, can result in a misdiagnosis of the myocardial abnormality.
The heart may exhibit normal wall motion but the area of the heart that is normally imaged may have moved out of the imaging plane and have abnormal motion that is not detected. Therefore, imaging all of the walls of the heart in multiple views and angles can prevent misdiagnosis of abnormal wall motion.
The axis serves as the anatomical reference for the standard echocardiographic imaging planes Figures 1, 2 : Long Axis LAX Four Chamber 4C Short Axis SAX The long axis runs from the apex of the heart through the base of the heart and the long axis of the aortic valve. The 4 chamber axis is perpendicular the the long axis but includes all four chambers of the heart.
The short axis is perpendicular to the long axis and the 4 chamber axis. The cardiac imaging planes are established referenced planes , whether the heart is viewed from the esophagus as in TEE , or from the chest wall as in TTE.

Important limitation of the study is the lack of contrast agents used to improve endocardial borders visualization. However, contrast echocardiography requires a venous access and is not routinely performed, despite improvement accuracy provided for LV volumes and EF assessment.
In addition, the use of CMR as the gold standard for EF has limitations related to the difficulty to accurately define the first basal slice and the spatial resolution of the apical region.

As the popularity of cosmetic surgery rises, the incidence of female patients with breast implants undergoing echocardiography will increase. All our cases had silicone implants limiting our observation to breast implants containing silicone. Furthermore, the effect of the outer layer of breast implants on the image quality is not known.
Silicone breast implants could produce significant artifacts during echocardiographic examination of the heart. Clinicians should be aware of this problem and women should be educated about the potential future diagnostic limitations that could occur as a result of having breast implants when they are considering breast augmentation.
