Pregnancy is not recommended for women with myocardial densification insufficiency because pregnancy may aggravate the heart. Myocardial densification insufficiency generally refers to myocardial densification insufficiency, which is a type of cardiomyopathy characterized by abnormally thick trabeculae and interlocking deep crypts within the ventricles. The main clinical manifestations of the patient are heart failure, arrhythmia and recurrent syncope, and even sudden death. Therefore, women with this disease are not allowed to get pregnant, and the risk of pregnancy is too high. The exact pathogenesis of myocardial densification insufficiency is not clear, but it may be related to the fact that the process of myocardial densification stops during the embryonic period. There is no specific treatment for myocardial densification insufficiency, and it is treated in cases of heart failure, arrhythmias, and combined cardiac malformations. Pregnancy is not recommended in women with myocardial insufficiency. The patient should consult a cardiovascular physician for treatment.
