Residual Mitral Regurgitation After Repair for Posterior Leaflet Prolapse—Importance of Preoperative Anterior Leaflet Tethering

Figures

• 

  Figure 1. Preoperative transesophageal echocardiography findings in representative patients in (A) control and (B) residual MR groups. Marked AML tethering (43°) was noted in the residual MR group case (Video S3). AL indicates anterolateral; AML, anterior mitral leaflet; MR, mitral regurgitation; PM, posteromedial.

  Figure 2. Representative residual MR group patient. The AML was tethered and its base thickened (arrowhead), resulting in reduced leaflet mobility (Video S4). AML indicates anterior mitral leaflet; MR, mitral regurgitation.
