Abstract
Long-term (>3 years) follow-up data were obtained from 102 consecutive patients undergoing percutaneous mitral balloon valvotomy (PMBV). Data were collected prospectively by review of the medical record, mailed questionnaire, and/or telephone. Data on patients with closed mitral commissurotomy (CMC) at our institution have been previously reported and serve as the comparison group. Follow-up data was 98% complete at a mean of 57 months for PMBV patients. Compared with patients undergoing CMC, these patients were older (54 ± 14 vs 43.6 ± 10 years, p <0.001) and more likely to have undergone previous mitral valve surgery (17% vs 4%, p <0.001). The observed 5-year survival in the PMBV group was no different from that observed in the CMC group (83% vs 90 %, p = NS) or from that predicted by the model developed from the CMC patients. Commissural calcium was associated with death and death or repeat mitral valve procedure in the multivariate analysis. Long-term survival free from repeat procedures was equivalent when patients with commissural calcium were excluded. Thus, PMBV offers long-term survival and freedom from subsequent mitral valve procedures similar to CMC. Copyright (C) 1999 Excerpta Medica Inc.
