“…In our study, a very good correlation was also seen between change in Cn with improvement in NYHA FC and exercise capacity along with regression of sPAP over a period of 24 weeks post BMV compared to baseline. Rajib et al also showed that post BMV Cn significantly correlated with NYHA FC assessed after BMV at 72 h. 3 Our study also showed good correlation between improvement in Cn and NYHA FC assessed after BMV at 2 weeks with further improvement uptill 12 weeks. At baseline 43 (86%) patients were in NYHA class III and 7 (14%) were in class IV.…”

“…In our study, there was a significant improvement in Cn acutely following BMV which is in agreement with two studies which assessed the acute effects of BMV on Cn. 3 , 11 Cn has also shown a very good correlation with sPAP. 4 , 9 , 17 , 18 Our study results are in agreement with these studies.…”

“… 1 The most commonly accepted criteria for successful BMV is an increase in MVA to ≥1.5 cm 2 or ≥ 50% increase from baseline without the development of significant mitral regurgitation (MR). 2 , 3 But this improvement in MVA per se does not lead to uniform clinical improvement in all patients.…”

“…4 However the effect of BMVon Cn has not been well studied. Two studies 3 , 11 have reported about significant improvement in Cn acutely after successful BMV while one study 12 assessed change in Cn over a period of 24 weeks. To the best of our knowledge, no study till date has assessed the correlation of change in Cn following successful BMV with clinical outcome over a 24 week period (change in NYHA FC or exercise capacity).…”

Aim of the study Patients undergoing successful balloon mitral valvuloplasty (BMV) have variable improvement in New York Heart Association (NYHA) functional class (FC), exercise capacity (EC) and regression of systolic pulmonary artery pressure (sPAP). Improvement in net atrioventricular compliance (Cn), one of the major determinants of above factors is not routinely assessed. Aim of present study was to assess the change in Cn after successful BMV and its correlation with above factors. Methods 50 patients of very severe mitral stenosis in sinus rhythm who underwent successful BMV have been studied. NYHA FC, 6 min walk test (6 MWT) and echocardiographic evaluation was done 24 h before and at 2 weeks, 12 weeks and 24 weeks after BMV. Echocardiographic parameters of patients with improvement in NYHA class of ≥2 (group A) were also compared with those with improvement in NYHA class of ≤1 (group B). Results Following successful BMV, there was progressive improvement in Cn upto 12 weeks with no further significant improvement till 24 weeks. Change in Cn showed very good correlation with change in NYHA class [ r = 0.62, p < 0.01], 6 MWT [ r = 0.30, p0.03] and regression of sPAP assessed at 12 weeks and was maintained upto 24 weeks. Change in MVA did not show any correlation with above factors. Group B patients had significantly lower Cn post BMV as compared to group A patients inspite of comparable MVA and trans valvular gradients. Conclusion Improvement in Cn following BMV has good correlation with clinical improvement. So Cn should also be assessed along with MVA to better predict clinical outcome.
