Real-Time 3-Dimensional Echocardiography

Real-time three-dimensional transthoracic echocardiography.

BACKGROUND Complex anatomy of intra-cardiac structures requires spatial orientation of image in three dimensions for better understanding and enhanced image interpretation. We evaluated the feasibility and efficacy of the emerging 'real-time three-dimensional transthoracic echocardiography' technique for comprehensive assessment of cardiac anatomy, physiology, pathomorphology and pathophysiolog...

Real-Time 3-Dimensional Transesophageal Echocardiography: Its Incremental Value over 2-Dimensional Echocardiography in Assessing Acute Mitral Regurgitation.

Feasibility study for real time three dimensional Doppler intracardiac echocardiography.

Using catheter-mounted two-dimensional array transducers, we have obtained real-time three-dimensional color flow and spectral Doppler ultrasound images in phantoms. We have constructed several transducers operating at 5 MHz with up to 137 channels inside a 12 French catheter lumen. The transducer configuration may be side scanning or beveled with respect to the long axis of the catheter lumen....

Left ventricular ejection fraction by real-time three-dimensional echocardiography

Despite a staggering technical progress in echocardiography, in daily clinical practice assessment of left ventricular (LV) ejection fraction (EF) is still often done in a rather inaccurate two-dimensional (2D) manner. Real-time three-dimensional echocardiography (RT3DE) provides a more representative realistic view of LV volumes, thereby being the Necker cube for the naive realism of 2D method...

Real-Time 3-Dimensional Echocardiography of the Heart 13 Years After Partial Left Ventriculectomy

A 69-year-old woman diagnosed as having end-stage dilated cardiomyopathy had undergone partial left ventriculectomy (PLV) in 1996. This is the first reported case of PLV (Batista procedure) in Korea. She was doing well under the New York Heart Association class II diagnosis in November 2009 and had received 3-dimensional (3D) echocardiography for the evaluation of cardiac function. Full volume ...
