Background: Reportedly, left ventricular (LV) mechanics are worsened in patients with mitral stenosis (MS) compared to controls. The immediate effect of balloon mitral valvuloplasty (BMV) on LV mechanics is, however, not known. Aim: To assess the immediate effect of balloon mitral valvuloplasty on the left ventricular twist mechanics. Methods and results: We studied 39 candidates for BMV. Pressures were measured invasively before and after BMV. Speckle tracking echocardiography (STE) was done for twist mechanics (basal rotation, apical rotation, and torsion) before and immediately after BMV. Twist mechanics were also measured by STE in 15 normal subjects as control group. Mean age was 30.4 ± 7.2 years, mean BMI was 24.7 ± 3.1 and 28 patients (72%) were females. All twist mechanics apical rotation and torsion were lower post-BMV compared to pre-BMV. Left ventricular end diastolic pressure was significantly higher post compared to pre-BMV while left atrial pressure (LAP) was similar between both groups. Importantly, patients who showed an increased LVEDP post compared to pre-BMV had worse LV twist mechanics than those whose LVEDP post-BMV was similar to or lower than pre-BMV. Conclusion: LV twist mechanics are worsened in MS with a further worsening, immediately after BMV probably because of failure of the LV to adapt to the sudden increased preload.

“…Pamir et al (1997) suggested that although the left atrium pressure following PMV decreased, the early diastolic filling fraction of the left ventricle did not change, and the LV end diastolic pressure increased significantly after PMV. It has been concluded that the diastolic dysfunction did not recover at an early stage following PMV (Pamir et al 1997). In our study, despite the increase of the valve area and the decrease of …”

It has been suggested that successful percutaneous balloon mitral valvuloplasty (PMV) decreases the intensity of spontaneous left atrial contrast, reduces the size of the left atrium, and improves left atrial function in patient with mitral stenosis. However, left atrial mechanical functions immediately after PMV have not been extensively evaluated yet. The aim of this study was to evaluate the effects of PMV on left atrial mechanical functions. Twenty patients with critical mitral stenosis who have normal sinus rhythm (male/female: 4 to 16; mean age: 33 ± 8 years) were included in the study. Left atrial mechanical functions were evaluated before and after PMV, including left atrial passive emptying volume, LA passive emptying fraction, conduit volume, left ventricular stroke volume, LA active emptying volume, LA active emptying fraction, LA total emptying volume and LA total emptying fraction. PMV resulted in a significant increase in the mitral valve area ( p < 0.001) and a substantial reduction in the mean transmitral pressure gradient ( p < 0.001) as well as LA diameter ( p < 0.002). LA maximal volume, minimal volume and atrial presystolic volumes were significantly decreased after PMV ( p: 0.001; p: 0.002; p: 0.001, respectively). The conduit volume was increased and LA total emptying volume was decreased after PMV ( p: 0.014; p: 0.035). The other left atrial volumes were not altered after PMV. The early increase in conduit volume and the decrease in left atrial presystolic volume indicate that PMV has favorable effects on atrial reservoir and conduit functions. PMV therefore improves atrial mechanic functions. left atrial mechanical functions; percutaneous mitral valvuloplasty; mitral stenosis
