Effect of balloon mitral valvotomy on left ventricular function in rheumatic mitral stenosis

Abstract

There were significantly lower mitral annular motion parameters including MAPSE in patients with rheumatic mitral stenosis. Those with atrial fibrillation had higher MPI. Immediately after BMV, there was improvement in LV long axis function with a gradual improvement in global LV function. There was no significant change of MAPSE after BMV.

Percutaneous balloon mitral valvuloplasty in rheumatic mitral stenosis: the earlier the merrier?

“…The authors showed a significant improvement in MASV, E', and MPI already within 24 hours after the procedure, whereas LVEF and MAPSE did not show statistically significant changes, consistent with other studies (7). One explanation for this finding may be related to the normal mitral annulus excursion present in patients with preserved EF.…”

“…Although EF is preserved in the majority of patients with pure MS (3), a subclinical LV dysfunction could be present (4,5). Nevertheless, the etiology and prevalence of LV dysfunction are still debated, with studies reporting estimates ranging from 21% to 77% (6,7). In addition to EF, other echocardiographic parameters can be used to assess LV dysfunction, such as mitral annular plane systolic excursion (MAPSE) and myocardial performance index (MPI).…”

“…MS is a mechanical disease; therefore, once symptoms appear and obstruction becomes significant, percutaneous mitral balloon valvuloplasty (PBMV) or surgery could provide symptom relief and improve survival (11). After PBMV, most of the aforementioned parameters change, confirming the existence of LV dysfunction in MS. (7,12). In the current issue of the Journal, Singh and colleagues (6) aim to evaluate the effect of PBMV on LV function using the previously mentioned echocardiographic parameters, and to determine predictors of LV function after PBMV.…”

Immediate impact of successful percutaneous balloon mitral valvuloplasty on right and left ventricular functions: An echocardiographic study using load independent tissue velocity imaging indices

“…Various studies have evaluated either left4, 13, 14, 15 or right ventricular3, 16, 17, 18 functions before and after PBMV, through TVI. But the data relating to simultaneous evaluation of both ventricles is scarce.…”

“…This ultimately results in right ventricular dilatation and dysfunction 3 . MS leads to alteration in interaction between right and left ventricles, myocardial fibrosis and decrease in preload, which probably delineate to be a cause for left ventricular (LV) dysfunction 4 …”
