Percutaneous Mitral Commissurotomy in Patients with Calcific Mitral Stenosis

Objective: the study evaluated the clinical and echocardiographic data, before and after percutaneous mitral commissurotomy (PMC) in patients with calcific mitral stenosis.nbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbsp Materials and methods: this is a retrospective study of 215 patients divided into two groups: 148 patients with calcific mitral stenosis (Group 1), and 67 patients without mitral calcifications (Group 2). The study period is between January 2011 to July 2015.Results: the group 1 was significantly older than the group 2 (49,7plusmn12,2 (group 1) versus 42,7plusmn12,8(group 2) , plt0,001), and had significantly more men than women (female gender:75% in group 1 vs.88,1% in group 2, plt0,05). Before PMC: group 1 had significantly higher Wilkins (9,3plusmn0,8(group 1) vs. 8,5plusmn0,6 (group 2)nbspnbsp p lt0,001) and smaller mitral valve area (0,91plusmn0,20 (group1)nbsp vs.0,99plusmn0,20 ( group 2), plt0,05). After PMC: the final valve area was significantly smaller in patients with, than, without calcifications (2,10plusmn0,26 vs.2,20plusmn0,22nbsp plt0,05). However , the rate of good immediate results, defined as valve area ge1,5 cmsup2 with no mitral regurgitation gt2/4 ( 97,9%vs.100% , pgt 0,05), and the rate of post PMC mitral regurgitation (MRge3/4) (2% vs.0% , pgt0,05), were no different between the 2 groups.Conclusion: PMC can be used for the treatment of patients with calcific mitral stenosis safety, with good immediate results.nbsp nbs
