Abstract
Immediate and mid-term results of percutaneous mitral commissurotomy (PMC) were assessed in 75 patients aged
70 years (mean 75±4 years (70 to 86)). Co-morbidities were present in 30 patients (40%), and 58 patients had calcified valves (77%). Technical failure occurred in two patients. PMC was performed in 73 patients, using a single balloon in five, two balloons in 28, and the Inoue balloon in 42.
After PMC, valve area increased from 10±02 to 16±03 cm2 as assessed by 2D echo (P<00001). Three procedural deaths occurred (4%). Good initial results (valve area
15 cm2 with mitral regurgitation
214) were obtained in 48 patients (66%). In multivariate analysis, predictors of poor initial results were previous commissurotomy (P=001) and valve calcification (P=004).
Mean follow-up was 24±18 months. The 4-year actuarial results were: survival in 59±l8%; no need for operation in 59±18%; and persistent good functional results (NYHA class I or II) in 34±16%. The only predictor of mid-term good functional results was the quality of initial results (P<0002). In conclusion, PMC in the elderly results in moderate but significant improvement in valve function at an acceptable risk: although subsequent functional deterioration is frequent. PMC is a useful although only palliative treatment in these patients.
