Atrial fibrillation with a structurally normal heart in pregnancy: An international survey on current practice.

Background Little evidence exists for the optimal management of atrial fibrillation with a structurally normal heart in pregnancy. Methods A survey was sent to members of two associations to obtain input on optimal management of atrial fibrillation in pregnancy. The survey presented four cases with respect to (1) baseline investigations; (2) rate versus rhythm control; (3) chemical versus electrical cardioversion; and (4) anticoagulation. Results Sixty-one responders from 11 countries participated. High agreement was noted for baseline investigations. A quarter (25%) of participants chose elective cardioversion even with a reversible precipitant. Electrical cardioversion was preferred over chemical (p < 0.05). Anticoagulation strategies were heterogeneous except in the presence of a left atrial appendage thrombus. Discussion This study revealed that there was little consensus in current practice in pregnancy beyond basic investigations. An adaptation of established guidelines to the pregnant population would require a meeting of Cardiologists with input from colleagues in Obstetric Medicine. [ABSTRACT FROM AUTHOR]
