“…This technique may have a limited ability to obtain reliable measures with multiple regurgitant jets; in the case of multiple MR jets, the fact that the respective widths of the VC are not additive must be taken into account, and in these cases the use VCW method is not recommended 21, 31, 42…”

BackgroundQuantitative and semiquantitative methods have been proposed for the assessment of MR severity, and though all are associated with limitations. Measurement of vena contracta width (VCW) has been used in clinical practice.ObjectiveTo measure the VCW in dogs with different levels of MR severity.AnimalsTwo hundred and seventy‐nine dogs were classified according to 5 levels of MR severity.MethodsThis was a retrospective study. EROA and regurgitant volume calculated by the PISA method, were measured and indexed to BSA. Descriptive statistics were calculated for VCW and VCW index for all categories of MR severity. Spearman's rank correlation coefficients (ρs) were calculated to compare the results of the different methods (VCW and VCW index vs RV PISA, RV PISA index, EROA, EROA index), and between VCW and VCW index versus MR severity.ResultsAll Spearman's rank correlation coefficients were significant (P < .001). The median values of VCW resulted of 2.9 mm (IQR 3.4–2.5) and of 4.6 mm (IQR 5.4–4.1) in the groups previously classified as mild‐to‐moderate and moderate‐to‐severe, respectively. The median values of VCW index resulted of 4.4 mm/m2 (IQR = 5.5–4.2) in mild‐to‐moderate MR and of 10.8 mm/m2 (IQR = 12.8–9.4) in moderate‐to‐severe MR.Conclusion and Clinical ImportanceThis is not a validation study against any previously validated invasive gold standard, the VCW method has proved easy to employ and it might be an additional tool in quantifying disease severity that supports, rather than replace, data coming from other techniques in daily clinical practice and research.

“…7.38 Diff erences in the asymmetry of the vena contracta area as visualized by RT3DE in patients with degenerative mitral regurgitation (MR), mitral valve prolapse (MVP), and functional MR. Source [14]; Copyright American Society of Echocardiography vided further validation of RT3DE assessment of the asymmetric VCA by comparison against independent methods [82] and the proof of superiority of 3D VCA measurements compared to 2D VCA measurement in both central and eccentric jets [83] as well as in multiple jets [84]. The overwhelming variability of shape, size, and number of VCAs in a spectrum of patients with both functional and organic MR is shown in .…”

“…Methods of assessment include quantitative Doppler and direct planimetry of effective regurgitant orifice area by 3D reconstruction. 27,28 However, after transcatheter devices are placed, these methods become less accurate or invalid because of Doppler flow acceleration and acoustic artifacts from devices. In the posttranscatheter edge-to-edge repair setting, multiple mitral regurgitation jets may be difficult to assess on TEE color Doppler imaging because of artifacts from the device(s).…”

Direct Measurement of Multiple Vena Contracta Areas for Assessing the Severity of Mitral Regurgitation Using 3D TEE

Abstract: Direct measurement of multiple VC areas using 3D transesophageal echocardiography allows for assessing MR severity in patients with multiple jets, particularly for MR degrees greater than mild and in cases of more than 2 jets, for which geometric assumptions may be challenging.
