Clinical and echocardiographic trends in percutaneous balloon mitral valvuloplasty.

BACKGROUND The prevalence of Rheumatic Mitral Stenosis (MS) has significantly changed over the last decades. We intend to examine patient demographics, Echocardiographic characteristics, procedural success rates, and complications throughout 30-years. METHODS We conducted a single-center descriptive observational study. The study population consists of patients undergone percutaneous balloon mitral valvuloplasty (PBMV) at Emek Medical Center in Israel from January 1990 to May 2019. RESULTS Four hundred seventeen patients underwent PBMV during the study period and were eligible for the study. Age did not change significantly over time (p = 0.09). The prevalence of Male and patients who were smoking and had multiple comorbidities such as hypertension, dyslipidemia, ischemic heart disease, and chronic kidney disease became increases over time (p = 0.02, p = 0.02, p = 0.001, p = 0.01, p = 0.02, and p = 0.001, respectively). Wilkins score and all its components increased over time, and the total score was higher in females (p = 0.01). Seventy-nine (18.9%) patients had complications. The rate of complications did not change over decades. Patients with Wilkins score > 8, post-procedural MR of ≥2, and post-procedural MVA  8, post-procedural MR of ≥2, and post-procedural MVA < 1.5 cm2 were in-depended predictors for the time for surgery and heart failure hospitalization.
