Key result
Transseptal double-balloon PMBV successfully achieves commissural splitting in mitral stenosis.
Case Report (n=1)
Illustrates the double-balloon technique via the transseptal route for percutaneous mitral balloon valvotomy, demonstrating the characteristic balloon waist prior to commissural splitting in a stenotic mitral valve.

Provides proof-of-concept for double-balloon transseptal PMBV; leaves open safety, efficacy, and generalizability in larger cohorts.
Percutaneous Mitral Balloon Valvotomy by Means of the Double-Balloon Technique. The inflation of 18-mm (above) and 20-mm (below) dilating balloons can be seen in a stenotic mitral valve. Note the waist produced by the stenotic valve (arrows) before full inflation causes commissural splitting. The balloons were placed in the mitral valve over two transfer wires passed through the right femoral vein, the interatrial septum (the transseptal route), and the mitral valve into the left ventricle, the aorta, and the descending aorta.

Eagle et al. (1992) conducted a case report in Stenotic mitral valve (mitral stenosis) (n=1). Percutaneous mitral balloon valvotomy by means of the double-balloon technique (18-mm and 20-mm dilating balloons via transseptal route) was evaluated on Commissural splitting of the stenotic mitral valve. Percutaneous mitral balloon valvotomy using 18-mm and 20-mm dilating balloons via the transseptal route produced full inflation and commissural splitting of the stenotic mitral valve.
