Single Balloon versus Inoue Balloon in Percutaneous Mitral Balloon Valvuloplasty. Short-term Results and Complications Purpose -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±14mmHg, p=0.2033, mean mitral gradient 17±6 and 20±7mmHg, p=0.0396 and MVA 0.9±0.2 and 0.9±0.2cm 2 , p=0.8043 and pos-PMBV: MPAP 25±8 and 28±10mmHg, p=0.2881, gradient 5±3 and 5±4mmHg, p=0.2778 and MVA 2.2±0.2 and 2.0±0.4cm 2 , 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).Conclusion -Both techniques were effective.Hemodynamic data were also similar although MVA was greater in IB group after PMBV.
