Pregnancy in women with biological heart valve prostheses is safe and does not accelerate the need for valve replacement. This study found no increased risk of valve re-replacement or complications during pregnancy for these patients.
Area of Science:
- Cardiology
- Reproductive Medicine
- Biomaterials Science
Background:
- Women with biological heart valve prostheses may face accelerated degeneration.
- Pregnancy poses potential risks to the longevity of these devices.
Purpose of the Study:
- To analyze the rate of prosthesis replacement in women with biological heart valve prostheses.
- To evaluate the outcomes of pregnancies in this patient group.
Main Methods:
- A cohort of 100 female patients (aged 18-40) who underwent valve replacement with bioprosthesis or homograft between 1976-2006.
- Follow-up evaluation of 87 patients via questionnaire at a mean interval of 10.8 years.
Main Results:
- 33 patients (38%) experienced 56 pregnancies with a 77% live-birth rate; no maternal deaths or thromboembolic events occurred.
- No structural valve deterioration was observed during pregnancy.
- 31 patients (36%) required re-replacement, with neither pregnancy nor valve type being a risk factor.
Conclusions:
- Pregnancy does not accelerate the risk of biological heart valve prosthesis replacement.
- Pregnancy can be safely undertaken in women with biological heart valves without increased valve-related morbidity.
