The report is remarkable because the population required to derive a meaningful experience from patients undergoing repeated procedures must be large. These authors draw from almost 1500 percutaneous balloon mitral valvotomy (PBMV) procedures, of which 90 patients ultimately underwent second and/or third dilatations.
