In the treatment of mitral stenosis, balloon valvuloplasty and open surgical commissurotomy have comparable initial results and low rates of restenosis, and both produce good functional capacity for at least three years. The potential complications associated with balloon valvuloplasty should be noted. The better hemodynamic results at three years, lower cost, and elimination of the need for thoracotomy suggest that balloon valvuloplasty should be considered for all patients with favorable mitral-valve anatomy.

This preclinical evaluation demonstrates the safety and efficacy of a novel cobalt chromium stent with a carbon-carbon coating and low and medium doses of paclitaxel.

A 28-year-old woman with mirror-image dextrocardia and severe rheumatic mitral stenosis underwent successful percutaneous balloon mitral valvuloplasty (PBMV). Standard technique was altered to include transseptal catheterization via the left femoral vein and inter-atrial septal puncture with the transseptal needle rotated to a 7 o'clock position. The predilatation transmitral gradient (mean) of 16 mmHg decreased to 5 mmHg following PBMV. The valve area improved from 1.0 cm2 to 2.6 cm2. There were no complications. This case illustrates that transseptal catheterization can be accomplished safely in patients with unusual cardiac anatomy and mitral valvuloplasty can be performed in patients with mirror-image dextrocardia and rheumatic mitral stenosis.
