The assessment of left ventricular twist in anterior wall myocardial infarction using two-dimensional speckle tracking imaging.
Two-dimensional speckle tracking imaging allows noninvasive measurement of left ventricular (LV) strain, rotation, and displacement. We investigated whether LV twist would be depressed in anterior wall myocardial infarction (MI) as a result of reduced apical rotation. ⋯ Systolic twist was decreased and diastolic untwisting was depressed in accordance with LV systolic dysfunction in anterior wall MI. These results suggest the significant impact of global LV systolic function on LV twist and twist-displacement loops in patients with anterior wall MI.

Comparative StudyThree-dimensional versus two-dimensional transesophageal echocardiography in mitral valve repair.
We sought to compare the diagnostic performance of 3-dimensional (3D) versus 2-dimensional (2D) echocardiography in patients with regurgitant mitral valve. ⋯ Three-dimensional echocardiography offers high accuracy in mitral valve evaluation. It may complement 2D study in patients with complex valve anatomy, where surgical decisions are more difficult. The images can be easily interpreted by professionals without a high degree of experience.
