| الوصف: | Objectives: Cardiovascular magnetic resonance feature tracking (CMR-FT) is a novel tissue tracking technique developed for noninvasive assessment ofmyocardial function. This study aimed to assess the long-term effect of mitral valve repair in patients with severe primarymitral regurgitation (MR). Methods: Ten patients with severe primary MR were consecutively enrolled and underwent CMR with a 1.5 T MRI scanner (Siemens Magnetom Aera, Germany) before surgical mitral valve repair and one-year after surgery. Myocardial deformation was analyzed using a dedicated software (Medis Suite, The Netherlands). Left ventricular (LV) longitudinal strain (EllLV) was calculated from three long-axis (2-chamber, 3- chamber and 4-chamber) cine images and circumferential and radial (EccSAX, ErrSAX) strain were derived from three short-axis (basal, mid-ventricular and apical) cine images. Results: There was significant decrease in EllLV at one-year follow-up when compared with strain estimated before surgery (EllLV: -21.89 6 4.70% before surgery vs. -17.76 6 4.01% after surgery; p¼0.028). Also, there was significant decrease in ErrSAX (55.87 6 14.72% before mitral valve repair vs. 33.12 6 8.54% after valve repair; p¼0.015). The EccSAX at one-year follow-up was similar when compared withmeasurements derived before surgery (p¼0.374). Conclusion: Conclusion. Mitral valve repair surgery in patients with severe primary mitral regurgitation reduces LV longitudinal and radial strain assessed by CMR-FT. |
