Pregnancy in Desmin-Related Cardiomyopathy

Area of Science:

• Cardiology
• Genetics
• Obstetrics

Background:

• Desmin-related restrictive cardiomyopathy (DRCM) is a rare cardiac condition.
• The course of DRCM during pregnancy is largely undescribed due to its rarity.

Observation:

• A 28-year-old woman with a history of heart failure and DRCM successfully completed a pregnancy.
• Prenatal care involved beta-blockers, diuretics, and serial echocardiography.
• Delivery was at 39 weeks, with a vacuum-assisted procedure for fetal reasons.

Findings:

• The patient required a postpartum blood transfusion for anemia due to uterine atony.
• Maternal and neonatal outcomes were uncomplicated.
• Postpartum cardiac evaluation revealed stable maternal cardiac function.

Implications:

• Pregnancy in women with controlled DRCM is feasible but necessitates meticulous antenatal, intrapartum, and postpartum surveillance.
• This case suggests pregnancy may not cause lasting cardiac damage in women with DRCM.
