PERCUTANEOUS MITRAL VALVULOPLASTY IN 2 PR EGNANT-WOMEN

In women with a significative mitral stenosis that become pregnant, me dical treatment has limitations and surgical treatment is associated w ith maternal and fetal mortality. We report two pregnant women in whom a mitral valvuloplasty was performed in weeks 30 and 32 of pregnancy, using the single balloon Inoue technique. The indication for the proc edure was the persistence of functional capacity IV heart failure in s pite of hospital bed rest and the use of diuretics and beta-blockers. Basal mitral valvular area was 0.6 and 0.9 cm2 and improved to 1.7 and 1.8 cm2 after the procedure; six months later, the areas were 1. 5 an d 1. 7 respectively. The procedure was well tolerated and was performe d with abdominal and pelvic shielding. No complications occurred, whic h a#owed hospital discharge in functional capacity I; they were readmi tted for delivery, giving birth to two healthy girls. It is concluded that mitral valvuloplasty in safe and effective in pregnant women with mitral stenosis refractory to usual medical treatment.
