“…1). For example, several studies have employed 3D echo to demonstrate that functional MR involves annular dilatation, chordal tethering by displaced papillary muscles, and measurable systolic tenting of the mitral leaflets [1][2][3][4]. These studies have also demonstrated that the crescent-shaped leaflet coaptation defect of functional MR may be very different for the more circular or elliptical defect encountered with organic (degenerative or myxomatous) valve disorders [5••, 6].…”

Current three-dimensional (3D) echocardiographic technology, including live 3D transesophageal echocardiography and single-beat 3D color Doppler imaging, are providing valuable new insight into the mechanism and quantification of mitral valve dysfunction. In this review we discuss important applications of 3D volumetric leaflet imaging with emphasis on the distinction between organic and functional mitral regurgitation. We also discuss the added benefit of current and emerging 3D color Doppler methods for the quantification of mitral regurgitation severity. The limitations of the 2D proximal isovelocity surface area method are discussed, along with potential solutions provided by 3D color Doppler imaging methods that do not require assumptions about the converging flow geometry. Methods to directly measure the vena contracta area of a regurgitant jet are presented along with recent validation studies comparing this method to a reference standard of cardiac MRI. In brief, we review the established and emerging applications of 3D color Doppler techniques for the quantification of mitral regurgitation severity.

“…8,9 In addition, improved assessment of anatomy and function of valves was achieved through better detail (figure 1), as well as the first time use of 3D colour flow jets. [10][11][12][13] With further advancements in technology, a transition from stepwise to continuous rotational scanning was achieved, offering the possibility of acquiring a complete 3D dataset within a single breath-hold of ten seconds. However, equal to freehand imaging there was still the necessity to interpolate between essentially multiple 2D images, making the technique sensitive to motion artefacts by involuntary movement of heart and lungs.…”

Significant advances in three-dimensional echocardiography have made this modality a powerful diagnostic tool in the cardiology clinic. It can provide accurate and reliable measurements of chamber size and function, including the quantification of left ventricular mechanical dyssynchrony to guide patient selection for cardiac resynchron-isation therapy. Furthermore, three-dimensional echocardiography offers novel views and comprehensive anatomic definition of valvular and congenital abnormalities, improving diagnosis and preoperative planning. In addition, it is extremely useful in monitoring the effectiveness of surgical or percutaneous transcatheter interventions. As its efficacy for more and more clinical applications is demonstrated, it is clear that three-dimensional echocardiography has become part of the routine clinical diagnostic armamentarium. In this article, we describe the development of three-dimensional echocardiography over the last decades, review the scientific evidence for its current clinical use and discuss potential future applications.

“…3DE quantifi cation of color fl ow has recently been validated in adults by comparison with cardiac outputs obtained by thermodilution [ 42 ]. Application of this technique to pathologic states could lead to potentially more accurate measurements of regurgitant volumes and fractions [ 43 ].…”
