- Abstract
BACKGROUND: The extent of mitral annular (MA) remodeling and dysfunction is correlated with the severity of mitral regurgitation (MR) as well as left atrial (LA) and left ventricular (LV) dilation. MA dysflinccion may be a 11sefi.1l prognostic factor for operative timing and MR recurrence after successfiil mitral valve (MV) repair. The aim of this study was to evaluate additive prognostic factors of MA non-planarity using real-time 3D transesophageal echocardiography (RT3D-TEE) analysis in patients with chronic severe MR and preserved LV systolic function. METHODS: Forty-seven patients with chronic severe MR and preserved LV systolic flmction scheduled for MV repair were prospectively enrolled. Echocardiographic studies were performed before surgery and postoperatively within 2 weeks and at least 6 months after surgery. RT3D-TEE was performed before the operation and immediately post-operative. RESULTS: Mean age was 55.4 ± 15.1 years and M were male. Annulus height/body surface area (BSA) obtained via RT3D-TEE was correlated with the degree of postoperative LA remodeling. Patients were divided into two groups by average baseline annulus height/BSA. Patients with normal annular height had a smaller postoperative LV end-diastolic dimension, LV end-systolic dimension and LA volume index than patients with decreased annular height. Preoperative annulus height/BSA values strongly predicted postoperative LA remodeling. CONCLUSION: MA height may be a useful prognostic factor for determining the timing of surgery in patients with chronic primary MR. Annulus height/BSA assessed via RT3D-TEE may provide additional information predictive of postoperative LA remodeling after successfiil MV repair.
