Abstract：
UNASSIGNED: As Percutaneous mitral balloon valvotomy (PMBV) remains the keystone in treating mitral stenosis, we conducted this review to elucidate the cumulative frequency and predictors of complications following PMBV and their occurrence in various patient populations.
UNASSIGNED: We searched digital databases for relevant studies covering complications of PMBV and retrieved articles using the Medical Subject Heading (MeSH) keywords.
UNASSIGNED: A total of 37 articles (8 RCTs, 7 nonrandomized clinical trials, 22 observational studies) were selected for qualitative analysis. A total of 11,803 patients undergoing PMBV among 37 studies were included, with a mean success rate of 84.54%. The most common complication was mitral regurgitation (8.2%) followed by an atrial septal defect (2.4%). Other relevant complications like stroke, pericardial tamponade, rupture of mitral leaflets, and conduction abnormalities were present in <1% of the patients.

摘要：
未经批准：由于经皮二尖瓣球囊瓣膜切开术（PMBV）仍然是治疗二尖瓣狭窄的基石，我们进行了这篇综述,目的是阐明PMBV后并发症的累积频率和预测因素,以及不同患者人群中并发症的发生情况.
UNASSIGNED：我们在数字数据库中搜索了涵盖PMBV并发症的相关研究，并使用医学主题标题(MeSH)关键词检索了文章。
未经批准：共37篇文章（8项RCT，7项非随机临床试验，选择22项观察性研究)进行定性分析。在37项研究中，共有11,803例接受PMBV的患者被纳入，平均成功率为84.54%。最常见的并发症是二尖瓣返流（8.2％），其次是房间隔缺损（2.4％）。其他相关并发症，如中风，心包填塞,二尖瓣小叶破裂,<1%的患者存在传导异常。
