OBJECTIVE To assess short-term results and complications of percutaneous mitral balloon valvuloplasty (PMBV) performed with Inoue balloon (IB) and single low profile balloon (SB). METHODS We performed 390 PMBV procedures, 29 with IB and 337 with SB. There were no differences in age, sex, echocardiographic score distribution and echocardiographic mitral valve area (MVA). RESULTS We performed 29 complete procedures with IB and 330 of 337 in SB group. Comparing IB and pre and pos-PMBV data we obtained: mean pulmonary artery pressure (MPAP) 36 +/- 15 and 39 +/- 14 mmHg, p = 0.2033, mean mitral gradient 17 +/- 6 and 20 +/- 77 mmHg, p = 0.0396 and MVA 0.9 +/- 0.2 and 0.9 +/- 0.2 cm2, p = 0.8043 and pos-PMBV:MPAP 25 +/- 8 and 28 +/- 10 mmHg, p = 0.2881, gradient 5 +/- 3 and 5 +/- 4 mmHg, p = 0.2778 and MVA 2.2 +/- 0.2 and 2.0 +/- 0.4 cm2, p = 0.0362. Mitral valve (MV) was competent in 26 patients in IB and in 280 in SB group and we had +/4 mitral regurgitation in 3 patients in IB and in 57 in SB group (p = 0.3591) pre-PMBV respectively and pos-PMBV there was also no difference in MV competence (p = 0.7439). CONCLUSIONS Both techniques were effective. Hemodynamic data were also similar although MVA was greater in IB group after PMBV.

D008946 Mitral Valve Stenosis Narrowing of the passage through the MITRAL VALVE due to FIBROSIS, and CALCINOSIS in the leaflets and chordal areas. This elevates the left atrial pressure which, in turn, raises pulmonary venous and capillary pressure leading to bouts of DYSPNEA and TACHYCARDIA during physical exertion. RHEUMATIC FEVER is its primary cause.
