“…Regarding NILVD, in line with previous echocardiographic reports [11], CMR MV parameters differences in patients with and without MR in NILVD were different. Neither TA nor CD was associated to FMR.…”

“…Its presence, even in small degrees, carries a worse prognosis compared to patients without significant FMR [2,4,5] Several echocardiographic parameters have been established as determinants of FMR with proven clinical utility both for the selection of surgical candidates and for risk stratification [6][7][8][9][10]. Recently, differences in echocardiographic determinants of FMR between ischemic LV dysfunction (ILVD) and non-ischemic LV dysfunction (NILVD) have been published [11].…”

Functional mitral regurgitation (FMR) is frequent in left ventricular (LV) dilatation/dysfunction. Echocardiographic predictors of FMR are known. However, cardiac magnetic resonance (CMR) predictors of FMR have not been fully addressed. The aim of the study was to evaluate CMR mitral valve (MV) parameters associated with FMR in ischemic and non ischemic LV dysfunction. 80 patients with LV ejection fraction below 45% and/or left ventricular dilatation of ischemic and non ischemic etiology were included. Cine-MR images (steady state free-precession) were acquired in a short-axis and 4 chambers views where MV evaluation was performed. Delayed enhancement was performed as well. Significant FMR was established as more than mild MR according to the echocardiographic report. Mean age was 59 years, males 79%. FMR was detected in 20 patients (25%) Significant differences were noted in LV functional parameters and in most MV parameters according to the presence of significant FMR. However, differences were noted between ischemic and non ischemic groups. In the first, differences in most MV parameters remained significant while in the non ischemic, only systolic and diastolic interpapillary muscle distance (1.60 vs. 2.19 cm, P = 0.001; 2. 51 vs. 3.04, P = 0.008) were predictors of FMR. FMR is associated with a more severe LV dilatation/dysfunction in the overall population. CMR MV parameters are associated with the presence of significant FMR and are different between ischemic and non ischemic patients. CMR evaluation of these patients may help in risk stratification as well as in surgical candidate selection.

“…Furthermore, semi-rigid bands achieved higher CD with lower trans-mitral Dp since discharge to the end of follow-up when compared to the other two types of rings. CD is a well-known predictor of CIMR recurrence [23]. On the other hand, a recent study has demonstrated that successful RMA induces some degree of functional mitral stenosis [24].…”

“…Relative high incidence of inferoposterior infarction would be the reason why LV sphericity did not determine FMR severity in ICM in our study. Nagasaki et al 19 also demonstrated that LV sphericity mainly determined the MR severity of non-ICM but not ICM. Kwan et al 20 reported that the pattern of mitral valve deformation from the medial to the lateral side was asymmetrical in ICM with inferoposterior infarction, whereas it was symmetrical in non-ICM.…”
