A Case of Neonatal Atrial Flutter Treated by Propafenone after Fetal Echocardiographic Diagnosis

Perinatal atrial flutter is a potentially lethal arrhythmia. Management of this disorder is difficult and controversial. Fetal atrial flutter is a serious and life threatening rhythm disorder particulary when it causes hydrops; it may be associated with fetal death or neurological damage. Although the initial episode of flutter may be difficult to control, recurrence of atrial flutter after successful resolution of the arrhythmia seems highly unlikely and long-term prognosis is excellent. We experienced a case of a atrial flutter diagnosed in utero at $38^{+6}$ weeks' gestation by fetal cardiac echocardiography. He was treated with maternal digoxin, but he continued to have atrial flutter until delivery. Restoration of sinus rhythm occured with propafenone therapy in this patient after failure of initial digoxin therapy and direct current cardioversion.

태아 심초음파 검사로 진단 된 뒤 출생 후 Propafenone으로 치유된 신생아 심방조동 1례

저자들은 재태 연령 $38^{+6}$주에 태아 심초음파 검사에 의해 태아 심방 조동이 발견되어 산모에게 digoxin을 투여하였으나 효과가 없어 제왕 절개술을 통해 분만한 후, digoxin, 전기적 심율동 전환에 의해서도 치료되지 않아 propafenone을 복용하여 정상 동율동으로 회복된 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
