Abstract:
Objective:To investigate the clinical characteristics and pregnancy outcomes in pregnant women with left ventricular non-compaction (LVNC).Methods:The clinical data of seven pregnant women with LVNC from January 2011 to December 2021 in Beijing Anzhen Hospital,Capital Medical University were retrospectively analyzed, including age, gestational age of symptom first occured, LVNC history, clinical symptoms, New York Heart Association (NYHA) cardiac function class, echocardiography, blood brain natriuretic peptide (BNP), treatment and the maternal and fetal outcomes.Results:Five cases were diagnosed before pregnancy, of which there were three women with medication; one case diagnosed in the month of pregnancy; one case diagnosed at 36 weeks of gestation. NYHA cardiac function was grade Ⅰ in four cases and grade Ⅱ in three cases before or during the first trimester of pregnancy. Of the five pregnant women who underwent echocardiography, there were one case of left ventricular insufficiency, three cases of mild left ventricular dysfunction and one case of normal left ventricular function before or during the first trimester of pregnancy. Of the five pregnant women to the second and third trimester of pregnancy, there were one case of grade Ⅳ, one case of grade Ⅲ, two cases of grade Ⅱ-Ⅲ and one case of grade Ⅱ in NYHA class ; three cases of left ventricular insufficiency, two cases of normal left ventricular function by echocardiography four cases had cardiac symptoms at 15-24 weeks of gestation and were treated with medication. In four cases, blood BNP increased to 214-1 197 ng/L during pregnancy, and were 89-106 ng/L after termination of pregnancy. There were 4 cases with arrhythmia. Indications for termination of pregnancy: LVNC complicated with heart failure in two cases, LVNC complicated with decreased cardiac function and threatened preterm birth in one case, complicated with pregnancy at full term in two cases, LVNC complicated with severe pulmonary hypertension in one case, and left ventricular dysfunction in one case. Cesarean section in four cases in the third-trimester, in one case in the second-trimester, and forceps curettage in two cases were taken. Two full-term infants,two preterm infants were born without LVNC.Conclusions:Women diagnosed with LVNC and low left ventricular ejection fraction before pregnancy are more prone to decreased cardiac function during pregnancy. Carrying out pregnancy risk assessment and strengthening the multi-disciplinary team management of high risk factors in pregnancy are conducive to achieve good pregnancy outcomes.
