<br/><br/> BACKGROUND: Incidence and prevalence of mitral stenosis is declining in the US. We performed this study to determine recent trends in utilization, complications, mortality, length of stay, and cost associated with balloon mitral valvuloplasty.  CONCLUSIONS: In a large cross-sectional study of balloon mitral valvuloplasty in the US, we have reported trends of decreasing overall utilization and increasing procedural complication rates and cost over a period of 13 years.Copyright � 2014 Elsevier Inc.

METHODS: Utilizing the nationwide inpatient sample database from 1998 to 2010, we identified patients using the International Classification of Diseases, 9th Revision, Clinical Modification procedure code for "percutaneous valvuloplasty." Patients >18 years of age with mitral stenosis were included. Patients with concomitant aortic, tricuspid, or pulmonic stenosis were excluded. Primary outcome included death and procedural complications.  RESULTS: A total of 1308 balloon mitral valvuloplasties (weighted n = 6540) were analyzed. There was a 7.5% decrease in utilization of the procedure from 24.6 procedures/10 million population in 1998-2001 to 22.7 procedures/10 million population in 2008-2010 (P for trend = .098). We observed a 15.9% overall procedural complication rate and 1.7% mortality rate. The procedural complication rates have increased in recent years (P = .001), corresponding to increasing age and burden of comorbidities in patients. The mean cost per admission for balloon mitral valvuloplasty has gone up significantly over the 10 years, from
