Echo-Doppler assessment of arterial stiffness in pediatric patients with Kawasaki disease.
There is growing evidence to suggest increased arterial stiffness in patients with a history of Kawasaki disease (KD). Pulse-wave velocity (PWV) is the most validated measure of arterial stiffness. The aim of this study was to determine if aortic PWV is increased in children with KD. ⋯ Arterial stiffness was increased in children with KD. There was no association between acute-phase KD coronary involvement and PWV. This implies that patients with KD may be at increased cardiovascular risk in the future.

Multicenter StudyExperts and beginners benefit from three-dimensional echocardiography: a multicenter study on the assessment of mitral valve prolapse.
Three-dimensional (3D) transesophageal echocardiography (TEE) has been claimed to provide more information than two-dimensional (2D) TEE in the localization of mitral valve prolapse (MVP). However, most studies have been performed by experts in echocardiography, without accounting for differences in training or expertise. This multicenter study was designed to assess the differences between experts and inexperienced echocardiographers in localizing MVP and ruptured chordae tendineae using 2D and real-time 3D TEE. ⋯ The reported diagnostic advantage of 3D TEE over 2D TEE in MVP assessment for expert echocardiographers can be transferred to inexperienced echocardiographers. Inexperienced echocardiographers benefit from the technology to a greater extent than their expert colleagues.

Three-dimensional transesophageal echocardiographic evaluation of coronary involvement in patients with acute type A aortic dissection.
Acute Stanford type A aortic dissection (AAD) with coronary involvement is associated with high mortality. However, coronary involvement is not always successfully visualized by computed tomography and two-dimensional (2D) transesophageal echocardiography (TEE). The aim of this study was to test the hypothesis that three-dimensional (3D) TEE can detect coronary involvement in patients with AAD. ⋯ Three-dimensional TEE reduced the number of cases evaluated as unclear coronary involvement by computed tomography and 2D TEE. In patients with AAD, 3D TEE allows evaluation of the status of coronary ostia in the operating room.

Multicenter StudyRelationship between longitudinal strain and symptomatic status in aortic stenosis.
Global longitudinal strain (GLS) and basal longitudinal strain (BLS) assessed using two-dimensional speckle-tracking imaging have been proposed as subtle markers of left ventricular (LV) systolic dysfunction with potential prognostic value in patients with aortic stenosis (AS). The aim of this study was to evaluate the relationship between longitudinal strain and symptomatic status in patients with AS. ⋯ In this prospective multicenter cohort of patients with wide ranges of AS severity, symptoms, and LVEFs, BLS but not GLS was independently associated with symptomatic status. However, there was an important overlap among groups, and differences were close to measurements' reproducibility, raising caution regarding the use of longitudinal strain, at least as a single criterion, in the decision-making process for patients with severe asymptomatic AS.

Clinical Trial Controlled Clinical TrialNew three-dimensional speckle-tracking echocardiography identifies global impairment of left ventricular mechanics with a high sensitivity in childhood cancer survivors.
The aim of this case-control study was to assess the usefulness of three-dimensional (3D) speckle-tracking echocardiography in the evaluation of global left ventricular (LV) myocardial performance in adolescent and adult survivors of childhood cancers. ⋯ Three-dimensional speckle-tracking echocardiography enables the derivation of an index of LV global performance that incorporates LV 3D strain, dyssynchrony, and torsion for the sensitive detection of altered LV mechanics in childhood cancer survivors.
