Pregnancy outcomes in women with mitral valve prolapse and mitral valve regurgitation Academic Article uri icon

abstract

  • Purpose: To examine pregnancy and perinatal outcomes in patients with mitral valve disorders [mitral valve prolapse and/or mitral regurgitation; mitral valve disorders (MVD)]. Methods: A retrospective comparative study was conducted comparing all singleton deliveries, during the years 1988-2010, of women with and without known MVD. Women lacking prenatal care were excluded. Stratified analysis using logistic regression was performed to control for confounds. Results: Out of 233,194 singleton deliveries that occurred during the study period, 390 deliveries occurred in women with MVD. Using a multivariate analysis, advanced maternal age (OR = 1.06; 95 % CI 1.05-1.08; P < 0.001), recurrent abortions (OR = 1.62; 95 % CI 1.15-2.28; P = 0.005), hypertensive disorders (OR = 1.62; 95 % CI 1.17-2.26; P = 0.004) and Jewish ethnicity (OR = 2.21; 95 % CI 1.76-2.79; P < 0.001) were found to be significantly associated with MVD. Since cesarean sections (CS) were significantly higher in deliveries of patients with MVD (17.9 vs. 14 %; P = 0.025), another multivariate analysis was constructed, with CS as the outcome variable. MVD was not found to be an independent risk factor for CS (OR = 1.05; 95 % CI 0.79-1.37; P = 0.74). Conclusions: MVD associated with advanced maternal age, recurrent abortions, Jewish ethnicity and hypertensive disorders were not found to be an independent risk factor for CS.
