Concurrent percutaneous balloon valvuloplasty for combined tricuspid and pulmonic stenoses.

Percutaneous balloon valvuloplasty was successfully performed in a 55-year-old Chinese woman with severe recurrent tricuspid and pulmonic stenoses 11 1/2 years following open valvotomies. An Inoue balloon catheter with the balloon made of double-layered rubber and nylon micromesh was used. The orifices of the tricuspid and pulmonic valves increased from 13 to 27 mm in diameter and from 6 to 14 mm in diameter, respectively, following concurrent balloon valvuloplasties. The present report demonstrated for the first time the feasibility of percutaneous balloon valvuloplasty for combined valvular stenoses.

Percutaneous transseptal balloon mitral valvuloplasty: the Chinese experience in 30 patients.

The results of percutaneous transseptal balloon mitral valvuloplasty (PTBMV) in 30 Chinese patients with rheumatic mitral stenosis are reported. PTBMV with the Inoue balloon catheter was successfully performed in 27 patients without any significant complications. The mean left atrial pressure decreased from 20.15 +/- 6.75 to 7.06 +/- 4.54 mm Hg (p less than 0.001); mitral valve gradient decreased from 16.86 +/- 6.37 to 2.68 +/- 2.96 mm Hg (p less than 0.001); pulmonary systolic pressure decreased from 48.38 +/- 17.57 to 30.04 +/- 11.49 mm Hg (p less than 0.001); mitral valve area increased from 1.27 +/- 0.31 to 2.13 +/- 0.43 cm2 (p less than 0.001). Results of follow-up examinations at 8 to 20 months showed that both subjective and objective improvement was well maintained. PTBMV is a highly effective and safe nonsurgical method of relieving mitral stenosis.
