To assess short-term results and complications of percutaneous mitral balloon valvuloplasty (PMBV) performed with Inoue balloon (IB) and single low profile balloon (SB).
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).
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).
Both techniques were effective. Hemodynamic data were also similar although MVA was greater in IB group after PMBV.
评估使用Inoue球囊（IB）和单低轮廓球囊（SB）进行经皮二尖瓣球囊成形术（PMBV）的短期结果和并发症。
我们进行了390例PMBV手术，其中29例使用IB，337例使用SB。在年龄、性别、超声心动图评分分布和超声心动图二尖瓣面积（MVA）方面没有差异。
我们使用IB完成了29例完整手术，SB组337例中有330例完成。比较IB组和术前及术后PMBV数据，我们得到：平均肺动脉压（MPAP）分别为36±15和39±14 mmHg，p = 0.2033；平均二尖瓣压差为17±6和20±7 mmHg，p = 0.0396；MVA为0.9±0.2和0.9±0.2 cm²，p = 0.8043；术后PMBV：MPAP为25±8和28±10 mmHg，p = 0.2881；压差为5±3和5±4 mmHg，p = 0.2778；MVA为2.2±0.2和2.0±0.4 cm²，p = 0.0362。IB组26例患者二尖瓣（MV）功能正常，SB组280例患者二尖瓣功能正常；术前PMBV时，IB组3例患者有轻度二尖瓣反流，SB组57例患者有轻度二尖瓣反流（p = 0.3591）；术后PMBV时，MV功能也无差异（p = 0.7439）。
两种技术均有效。尽管PMBV后IB组的MVA更大，但血流动力学数据也相似。
