Comparison of clinical echocardiographic and hemodynamic characteristics of male and female patients who underwent mitral balloon valvuloplasty.

ABSTRACT

The clinical echocardiographic and hemodynamic characteristics and outcome of male and female patients before and after valvuloplasty were evaluated. The study population consisted of 34 male and 122 female consecutive patients who successfully underwent percutaneous balloon mitral valvuloplasty (PBMV). Clinical, echocardiographic, and hemodynamic variables were compared between male and female patients. Male patients were significantly older than female patients at the time of PBMV (39 years vs 34 years p < 0.05). Mitral valve score was significantly higher in male patients (p < 0.01). The mitral valve area before PBMV in male patients was significantly less than that in female patients (0.97 +/- 0.22 cm2 vs 1.09 +/- 0.25 cm2, respectively, p < 0.05). The pulmonary artery pressures of female patients before PBMV were higher than those of males (48 mm Hg vs 40 mm Hg, respectively, p < 0.05). The restenosis rates in male and female patients at the end of the follow-up period (38 months) were 20% and 9%, respectively (p < 0.05). In conclusion, male patients are older than female patients at the time of the PBMV procedure, and male patients have worse echocardiographic parameters and restenosis rates than female patients with the exception of pre-procedural pulmonary artery pressure.
