- Abstract
Background The objectives of this study were twofold: to assess the diagnostic utility of three-dimensional (3D) multiplanar reconstruction ( MPR) in identifying prolapsing mitral valve (MV) scallops, and (2) to compare two-dimensional (2D) transthoracic echocardiography ( TTE) and 3D MPR to (2D) transesophageal echocardiography ( TEE) approaches among patients with mitral valve prolapse ( MVP). Methods Fifty-five patients with MVP who underwent MV repair or replacement were retrospectively analyzed using 3 types of echocardiographic studies (2D TEE, 2D TTE, 3D MPR). The operative ( OR) findings were considered the gold standard. Results When 3D MPR was combined with 2D TTE, the agreement with the OR findings was moderately strong for the A2 scallop (P < 0.001) and strong for the A3 scallop (P = 0.001), entire anterior leaflet (P < 0.001), P2 scallop (P < 0.001) and the entire posterior leaflet (P < 0.001). In comparison to the OR findings, 2D TEE demonstrated moderately strong agreement for the A2 scallop (P = 0.010) and the entire anterior leaflet (P < 0.001), and strong agreement for the P2 scallop (P < 0.001) and entire posterior leaflet (P < 0.001). Conclusions Three-dimensional MPR should be added to the armamentarium of complementary echo techniques in the evaluation of MVP. There is increased benefit in combining 3D MPR with 2D TTE findings as part of the preoperative evaluation of patients with MVP.
