“…Although RT3DE zoomed acquisition can be difficult to perform in patients with an exceedingly large annulus, only 1 of the 57 DMVD patients who were screened was excluded from our study for this reason. Because surgical inspection is performed in an immobile, flaccid state, as opposed to echocardiographic assessment, which visualizes the valve in a dynamic state, it can potentially result in discrepancy between the methodologies, 39 one might construe that using surgical findings as the gold standard reference might be a limitation of our study. However, this ability of morphological analysis to detect small, not easily visible areas of billowing, whereas increasing the sensitivity of RT3DE is likely to be diagnostically inconsequential.…”

Background-Presurgical planning of mitral valve (MV) repair in patients with Barlow disease (BD) and fibroelastic deficiency (FED) is challenging because of the inability to assess accurately the complexity of MV prolapse. We hypothesized that the etiology of degenerative MV disease (DMVD) could be objectively and accurately ascertained using parameters of MV geometry obtained by morphological analysis of real-time 3D echocardiographic (RT3DE) images. Methods and Results-Seventy-seven patients underwent transesophageal RT3DE study: 57 patients with DMVD studied intraoperatively (28 BD, 29 FED classified during surgery) and 20 patients with normal MV who were used as control subjects (NL). MVQ software (Philips) was used to measure parameters of annular dimensions and geometry and leaflet surface area, including billowing volume and height. The Student t test and multinomial logistic regression was performed to identify parameters best differentiating DMVD patients from normal as well as FED from BD. Morphological analysis in the DMVD group revealed a progressive increase in multiple parameters from NL to FED to BD, allowing for accurate diagnosis of these entities. The strongest predictors of the presence of DMVD included billowing height and volume. Three-dimensional billowing height with a cutoff value of 1.0 mm differentiated DMVD from NL without overlap, and billowing volume with a cutoff value 1.15 mL differentiated between FED and BD without overlap. Conclusions-Morphological analysis as a form of decision support in assessing MV billowing revealed significant quantifiable differences between NL, FED, and BD patients, allowing accurate classification of the etiology of MV prolapse and determination of the anticipated complexity of repair.

“…Orientation using the surgical clock (by rotating the image to place the aortic valve at 12 O’clock) is important for localizing prolapse and conveying results immediately to the surgeon 4 . Further experience in cropping these datasets should empower investigation similar to our past experience with reconstructive 3D TEE and live/real time 3D TTE 4–6 …”

A new tool has been recently introduced to the echocardiography armamentarium, live/real time three-dimensional (3D) transesophageal echocardiography (TEE). In these cases, we describe our initial experience in 13 patients studied intraoperatively and in the echocardiography suite. This important technology promises improved anatomic definition, diagnostic confidence, and novel views of the complicated cardiovascular pathology encountered in common clinical practice.

“…Most of these studies assessed the accuracy of 3D reconstructed images, not RT3D. Recently, Patel et al reported that RT3D showed high sensitivity and specificity in comparison with surgical findings 32 . Our study was designed to seek out clinical features of RT3D by means of comparing with 2D TTE and TEE.…”
