Comparison of open commissurotomy and balloon valvuloplasty in mitral stenosis. A five-year follow-up.

Objective: To compare clinical and laboratory data in patients with mitral stenosis undergoing open commissurotomy or balloon valvuloplasty, who were followed up for 5 years.

Methods: Eighty-one patients were prospectively assessed prior to the procedure (PRE) and immediately after the procedure, in the immediate postoperative period (IPO), and followed up yearly for 5 years (PO12M, PO24M, PO36M, PO48M, and PO60M). They were randomized into the following 2 groups: GC (group undergoing open commissurotomy): 37 patients (32.

Comparison between percutaneous balloon valvuloplasty and open commissurotomy for mitral stenosis. A prospective and randomized study.

Eighty patients with tight and pliable mitral stenosis were randomized in a prospective trial comparing percutaneous balloon valvuloplasty and open commissurotomy. Mitral valve area increased significantly in both groups immediately after the procedures. However, a decrease in mitral valve area occurred in both groups at 6, 12 and 24 months during the follow-up.
