Short-term Changes in Aortic Regurgitation after Percutaneous Mitral Valvuloplasty

The aim of this study was to evaluate the short- term effects of percutaneous mitral valvuloplasty (PMV) on coexisting AR.

Clinical, echocardiographic and catheterization data from hospital records of a total of 327 patients with rheumatic mitral stenosis who underwent PMV at a tertiary centre were retrospectively reviewed and aortic regurgitation changes 48 hours post PMV was recorded.

The study population consisted of 282 females and 45 males. Mean age at the time of intervention was 47.13±11 years. Before PMV, 142 (43.3%) patients had no AR, 124 (37.9%) had mild AR and 61 (18.7%) had moderate AR. There was no change in AR severity in post- PMV follow-up. AR progression after PMV and during the follow-up was not significant and there was no increase in the need for aortic valve replacement (AVR) procedures.

Our findings indicated that a considerable number of patients with rheumatic mitral stenosis had concurrent AR. At the time of PMV concomitant AR does affect procedural success and is not associated with inferior outcomes. Patients with moderate degrees of AR remain good candidates for PMV.
