【摘要】Background Although acute rheumatic fever and rheumatic heart disease are now rare in affluent populations,they remain major health issues in developing countries such as China. Rheumatic mitral stenosis is the most common valvular disease during pregnancy. Some patients can receive percutaneous balloon mitral valvuloplastyduring pregnancy and obtain good outcomes. Methods A retrospective study of 14 women undergoing percutaneous balloon mitral valvuloplasty with rheumatic mitral valve stenosis during pregnancy in our hospital from Jan 2014 to Oct 2019 was conducted. The maternal and fetal outcomes were analyzed. Results Percutaneous balloon mitral valvuloplasty was successful in all patients with significant improvement in their mitral valve area(pre-operation:0.83±0.21 cm2 and post-operation:1.64±0.27 cm2,P<0.05). Pulmonary artery systolic pressure(pre-operation:69.62±28.27 mmHg and post-operation:37.23±12.65 mmHg,P<0.05)was significantly decreased. All 14 patients had an uneventful course afterthe operation. The total number of newborns was 14,none of whom required intensive care monitoring,and no malformations were found. Conclusions Percutaneous balloon mitral valvuloplasty performed during pregnancy with necessary precautions is feasible and effectivefor the mother and mightbe safe forthe fetus. There is marked symptomatic relief,along with good maternal and fetal outcomes.[S Chin J Cardiol 2020;21(1):47-52]
