Abstract:
Objective:To investigate the clinical characteristics and maternal-fetal outcomes of asymptomatic pregnant women with atrioventricular block(AVB).Methods:Clinical data were collected from 83 pregnant women with AVB treated at Beijing Anzhen Hospital,Capital Medical University,from January 2010 to December 2020.Pa-tients were classified into first-degree,second-degree Type I,second-degree Type Ⅱ and third-degree AVB based on the severity of atrioventricular conduction block.All patients were followed up by telephone,and a retro-spective analysis was conducted on their general information,clinical characteristics,and maternal-fetal out-comes.Results:Among the 83 patients,11 cases(13.3%)had first-degree AVB,28 cases(33.7%)had sec-ond-degree Type I AVB,9 cases(10.8%)had second-degree Type II AVB,and 35 cases(42.2%)had third-de-gree AVB.Most patients were primiparas(61 cases,73.5%)and had singleton pregnancies(80 cases,96.4%).AVB was diagnosed before pregnancy in 40 cases(48.2%)and during pregnancy in 43 cases(51.8%).A total of 32 patients received pacemaker therapy before pregnancy(3.6%),before delivery(26.5%),or after delivery(3.6%).Most patients had good cardiac function,with only 3 patients having gradeⅢcardiac function before de-livery,showing no statistically significant difference(P>0.05).Of the 83 patients,62 cases underwent cesarean section to terminate the pregnancy,with 17 cases(27.4%)due to AVB and 34 cases(54.8%)due to obstetric factors.Among the 86 newborns,8 cases(9.6%)were preterm,7 cases(8.4%)had low birth weight,and 1cases(1.2%)had congenital heart disease.Conclusions:Most pregnant women with AVB have good cardiac function and can achieve favorable maternal-fetal outcomes under multidisciplinary team management.
