Abstract

Background: Cardiac surgery during pregnancy often carries a high risk of death for both mother and baby. Herein, we report our experience of valvular surgery in pregnant patients. 


Methods: we retrospective review all of the pregnant patients associated with valvular surgery between 1998 and 2018 at Ho Chi Minh City Heart Institute. Both fetal and maternal outcomes have assessed to determine the effectiveness of surgical treatment.


Results: The total number of patients was 78, including 15 patients who had close mitral valvulotomy and 63 patients who had valvuloplasty or valvular replacement. The maternal and fetal mortality rate were 4.7% and 10.1%. Maternal outcomes were 20.5% (16) including low cardiac output, cardiac arrhythmia, and acute pulmonary edema. Fetal outcomes were 36.8% (28) including termination by cesarean (4), miscarriage (6), threatened abortion (13), pre-term delivery (3), and stillbirth (2). Factors that affect maternal mortality include pre-operative NYHA (p= 0.037) and type of operation (p =0.034). Factors that affect fetal outcomes include CPB time (p = 0.003) and aortic clamp time (p= 0.01). The average follow-up was 104.25 ± 68.7 months (range 12- 238) with 95% complete of follow-up.


Conclusions: Surgical treatment for pregnant patients with valvular heart disease remains a big challenge. The coordination of many medical specialists, optimization of CPB, optimization timing of surgery to give the best results for both mother and fetus.
