This\u00a0research sought to systematically compare the efficacy and  safety of mitral balloon and surgical valvotomy.\n        METHODS:  A systematic literature retrieval was performed for all clinical trials  comparing the outcomes of mitral valvotomy with balloon intervention  or surgery in Pubmed, EMBASE and the Cochrane Library.\n        RESULTS:  A total of 12 eligible, clinical studies, comparing mitral valvotomy using  percutaneous balloon intervention or thoracotomy surgery, were found between  1966 and 2010: seven prospective randomised trials and five case-control  trials. With follow-up ranging from one to seven years, there was no  significant difference in mortality (relative risk (RR) 0.97, 95% confidence  interval (CI) 0.45\u20132.09) and complications (RR 2.15, 95% CI 0.98\u20134.7) between  the two procedures. The pooling analysis obtained a significantly higher  occurrence of new-onset  mitral regurgitation after percutaneous balloon intervention relative to thoracotomy surgery (RR 1.66  95%CI 1.08\u20132.58).  Similarly, we obtained a higher RR of re-intervention in balloon intervention compared  to thoracotomy surgery of 2.88  (95% CI 1.97\u20134.2). In  addition, compared to those patients who had thoracotomy surgery, patients who  underwent percutaneous  balloon intervention presented a significantly worse effect in preserving  the mitral valve area: SMD \u20130.30, 95%CI: \u20130.42 - \u20130.18.\n        CONCLUSIONS:  Clinical evidence suggests there are comparable clinical outcomes in terms of  operative, late mortality and complications between percutaneous balloon and  surgical mitral commissurotomy. Incidences of new-onset mitral regurgitation  and late re-intervention are significantly higher after balloon intervention.<\/jats:p>","DOI":"10.4414\/smw.2011.13180","type":"journal-article","created":{"date-parts":[[2011,10,27]],"date-time":"2011-10-27T03:48:08Z","timestamp":1319687288000},"page":"w13180","source":"Crossref","is-referenced-by-count":4,"title":["Systematic comparison of the effectiveness of  percutaneous mitral balloon valvotomy with surgical mitral commissurotomy"],"prefix":"10.57187","volume":"141","author":[{"given":"Q","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"X","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"36756","published-online":{"date-parts":[[2011,4,11]]},"container-title":["Swiss Medical Weekly"],"original-title":[],"link":[{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1272\/1428","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1272\/1429","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/download\/1272\/1428","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T02:49:34Z","timestamp":1755226174000},"score":1,"resource":{"primary":{"URL":"https:\/\/smw.ch\/index.php\/smw\/article\/view\/1272"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,4,11]]},"references-count":0,"journal-issue":{"issue":"1516","published-online":{"date-parts":[[2011,4,11]]}},"URL":"https:\/\/doi.org\/10.4414\/smw.2011.13180","relation":{},"ISSN":["1424-3997"],"issn-type":[{"type":"electronic","value":"1424-3997"}],"subject":[],"published":{"date-parts":[[2011,4,11]]}}}
