“…According to these experiences, we assumed that the MV remodeling in patients with AR should be varied by the directions of AR jets. Today, three-dimensional (3D) transesophageal echocardiography (TEE) can provide a detailed quantification of the MV apparatus, including MV annulus area, anterior mitral leaflet (AML) and posterior mitral leaflet (PML) areas, and MV opening area 8 – 13 . We hypothesized that the directions of AR jets affect the MV apparatus and trigger AML enlargement in patients with chronic AR.…”

Chronic aortic regurgitation (AR) induces mitral valve (MV) leaflet enlargement, although, its mechanism still remains unclear. This study aimed to clarify the influence of AR jet directions on the MV apparatus in patients with chronic AR. This study included 69 consecutive patients with severe chronic AR and 17 controls who underwent three-dimensional (3D) transesophageal echocardiography (TEE). The anterior mitral leaflet (AML), posterior mitral leaflet (PML) and MV annulus areas were measured at mid-diastole. All AR patients were classified into the posterior (Group A, n = 38) or non-posterior (Group B, n = 31) group based on the AR jet directions. Both two groups revealed the increased total leaflet areas compared with the controls. No significant differences in the left ventricular volumes, PML or MV annulus area were observed between Group A and B; however, Group A had the larger AML area and greater AML/PML area ratio than Group B (both P < 0.01). The multivariate analysis indicated that the posterior AR jet was independently associated with the AML/PML area (P < 0.01). 3D TEE depicted geometric differences in the MV apparatus between the different types of AR jet directions. These results may be helpful in understanding the mechanism of MV leaflet remodeling in chronic AR.
