Summary

Even during mitral valve repair procedure (MVP) for severe mitral stenosis (MS), the intraoperative assessment of mitral valve area (MVA) is necessary for evaluating the severity of MS before the repair and excluding residual MS for immediate determination of the success of the repair procedure and postoperative prognosis. For this purpose, several methods have been applied by introperative transesophageal echocardiography (TEE): pressure half-time (PHT) of mitral inflow Doppler and 2-dimensional (2D) planimetry methods have been widely used in clinical practice. However, especially after MVP, the PHT method is usually unreliable because it usually underestimates the MVA due to various intraoperative hemodynamic factors.

The authors hypothesized that the MVA determined by 3D TEE would be more accurate than that by PHT during immediate post-MVP procedure in severe MS patients and comparable to postoperative MVA determined by MDCT. Therefore, the present study determined the MVA by using PHT, 3D planimetry and MDCT before and after the MVP procedure in severe MS patients and analyzed them to evaluate 3D TEE's utility for evaluation of MVA.
