Fetuses with critical aortic stenosis, severe mitral regurgitation and left atrial enlargement are at risk to develop heart failure and intrauterine death. We present two cases with this physiology who underwent fetal aortic balloon valvuloplasty at 25 + 5 and 28 + 2 weeks as their only intervention without requiring postnatal treatment during short- to medium-term follow-up of 1.4 and 4.9 years.

产前主动脉瓣成形术治疗危重主动脉瓣狭窄伴重度二尖瓣反流伴巨大左房胎儿的确定性治疗：附2例中期随访报告

患有严重主动脉瓣狭窄、严重二尖瓣反流和左心房扩大的胎儿有发生心力衰竭和宫内死亡的风险。我们介绍了两个具有这种生理学特征的病例，他们在 25 + 5 周和 28 + 2 周时接受了胎儿主动脉球囊瓣膜成形术作为他们唯一的干预措施，在 1.4 年和 4.9 年的短期至中期随访期间不需要产后治疗。
