Pregnancy is contraindicated in dilated cardiomyopathy. If the patient is mild and has an urgent need to have children, the decision to become pregnant should be made under close supervision of a physician, with clinical ancillary tests such as cardiac ultrasound and clinical progress of the disease. Patients who do not know they have Dilated Cardiomyopathy but are pregnant should be hospitalized as soon as possible for a full cardiac and physical evaluation to determine whether to continue the pregnancy or to actively terminate the pregnancy if it is very severe. Most cases of dilated cardiomyopathy are characterized by heart failure and arrhythmias. If the patient’s symptoms are usually severe, medication is required, which is also teratogenic to the fetus, and as the fetus grows, it increases the burden on the heart, so pregnancy is not recommended.
