“…The 3D VCA method eliminates geometric and flow assumptions and can be applied regardless of etiology and orifice shape . TTE 3D VCA has been used for MR, TR, AR, and prosthetic perivalvular regurgitation . Studies compared 3D VCA against 2D PISA EROA, angiographic grade, or Doppler‐derived EROA by the volumetric method with associated limitations of the reference standard.…”

Background Quantitation of regurgitation severity using the proximal isovelocity acceleration (PISA) method to calculate effective regurgitant orifice (ERO) area has limitations. Measurement of three‐dimensional (3D) vena contracta area (VCA) accurately grades mitral regurgitation (MR) severity on transthoracic echocardiography (TTE). Methods We evaluated 3D VCA quantitation of regurgitant jet severity using 3D transesophageal echocardiography (TEE) in 110 native mitral, aortic, and tricuspid valves and six prosthetic valves in patients with at least mild valvular regurgitation. The ASE‐recommended integrative method comprising semiquantitative and quantitative assessment of valvular regurgitation was used as a reference method, including ERO area by 2D PISA for assigning severity of regurgitation grade. Results Mean age was 62.2±14.4 years; 3D VCA quantitation was feasible in 91% regurgitant valves compared to 78% by the PISA method. When both methods were feasible and in the presence of a single regurgitant jet, 3D VCA and 2D PISA were similar in differentiating assigned severity (ANOVAP<.001). In valves with multiple jets, however, 3D VCA had a better correlation to assigned severity (ANOVAP<.0001). The agreement of 2D PISA and 3D VCA with the integrative method was 47% and 58% for moderate and 65% and 88% for severe regurgitation, respectively. Conclusion Measurement of 3D VCA by TEE is superior to the 2D PISA method in determination of regurgitation severity in multiple native and prosthetic valves.

“…Therefore, despite the common knowledge on the possible mechanisms of TR after cardiac device implantation, the clear evidence to explain the whole spectrum of TR could not be obtained using 2D TTE or TEE. However, with the more common usage of 3D echocardiography, insights to the definitive mechanisms of TR and relationship between TR and implanted leads can be defined more precisely [11].…”

“…Three dimensional echocardiography showed a better correlation and Kappa index of agreement, less dispersion, and narrower confidence limits than 2D echocardiography. 28 To estimate the severity of tricuspid regurgitation, 3D echocardiography was more accurate than 2D for determining the effective regurgitant orifice area and the regurgitant volume (especially in eccentric jets) by evaluation of the proximal isovelocity surface area (PISA), using quantitative Doppler and 3D planimetry as reference 29 (Figure 1). …”
