The aim of the study is to examine the effect of concomitant aortic regurgitation (AR) on percutaneous mitral valvuloplasty (PMV) procedural success, short-term, and long-term clinical outcome. No large-scale study has explored the impact of coexistent AR on PMV procedural success and outcome.


Demographic, echocardiographic, and procedure-related variables were recorded in 644 consecutive patients undergoing 676 PMV at a single center. Mortality, aortic valve surgery (replacement or repair) (AVR), mitral valve surgery (MVR), and redo PMV were recorded during follow-up.


Of the 676 procedures performed, 361 (53.4%) had no AR, 287 (42.5%) mild AR, and 28 (4.1%) moderate AR. There were no differences between groups in the preprocedure characteristics, procedural success, or in the incidence of inhospital adverse events. At a median follow-up of 4.11 years, there was no difference in the overall survival rate (P = .22), MVR rate (P = .69), or redo PMV incidence (P = .33). The rate of AVR was higher in the moderate AR group (0.9% vs 1.9% vs 13%, P = .003). Mean time to AVR was 4.5 years and did not differ significantly between patients with no AR, mild AR, or moderate AR (2.9 +/- 2.1 vs 5.7 +/- 3.6 vs 4.1 +/- 2.5 years, P = .46).


Concomitant AR at the time of PMV does not influence procedural success and is not associated with inferior outcome. A minority of patients with MS and moderate AR who undergo PMV will require subsequent AVR on long-term follow-up. Thus, patients with rheumatic MS and mild to moderate AR remain good candidates for PMV.
