Comparative StudyComparative accuracy of two- and three-dimensional transthoracic and transesophageal echocardiography in identifying mitral valve pathology in patients undergoing mitral valve repair: initial observations.
Identification of mitral regurgitation (MR) mechanism and pathology are crucial for surgical repair. The aim of the present investigation was to evaluate the comparative accuracy of real-time three-dimensional (3D) transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) with two-dimensional (2D) TEE and TTE in diagnosing the mechanism of MR compared with the surgical standard. ⋯ All modalities were equally reliable in identifying functional MR. Both 2D TEE and 3D TEE were comparable in diagnosing MR mechanism, while 3D TEE had the advantage of better localizing the disease. With current technology, 3D TTE was the least reliable in identifying valve pathology.

Comparative StudyUtility of right ventricular free wall speckle-tracking strain for evaluation of right ventricular performance in patients with pulmonary hypertension.
The objectives of this study were to test the utility of right ventricular (RV) speckle-tracking strain as an assessment tool for RV function in patients with pulmonary hypertension (PH) compared with conventional echocardiographic parameters and to investigate the relationship of the findings obtained with RV speckle-tracking strain with the hemodynamic parameters of RV performance. ⋯ RV-free has the potential to allow for noninvasive follow-up of patients with PH.
