This study evaluated the short and long-term consequences of Percutaneous Mitral Valvuloplasty (PMV) in pregnant patients and their offspring, in a tertiary care setting, Karachi, Pakistan. The hospital database was used to retrieve all patients who underwent PMV during pregnancy in the period 1998-2007. The follow up data of the patients and the born children were obtained from the hospital records and also by contacting the patients via phone. Six patients underwent PMV but follow-up was available for 5 patients only. All 5 patients were admitted due to severe mitral stenosis with symptoms of dyspnea and palpitation. Mean age was 27 +/- 5.3 years with a mean gestational age at the time of procedure of 22.20 +/- 1.6 weeks. The mean valve area increased from 0.94 +/- 0.22 cm2 preoperatively to 1.62 +/- 0.50 cm2 post-operatively. The ejection fraction changed from a mean of 50 +/- 11.7% to 56 +/- 2.2%. There were no maternal deaths, abortions or stillbirths. Developmental milestones were achieved at the appropriate ages in all babies. PMV appears to be a safe and effective intervention for patients with severe MS during pregnancy. Keywords: Mitral stenosis, Percutaneous Mitral
