Atrial fibrillation in pregnancy

Recurrent atrial flutter and fibrillation in pregnancy

“…In women with rheumatic mitral stenosis there is a substantial increased risk of thromboembolism and anticoagulation is mandated. Chemical cardioversion by drugs with class Ic antiarrhythmic properties, like flecainide, have been used in pregnancy11 but experience is limited.…”

Atrial Fibrillation in Pregnancy

“…2,3 In the third case, cardioversion was achieved with flecainide after rate control with atenolol. 4 Table 1 summarizes the reported cases of lone atrial fibrillation in pregnancy. All patients recovered well from their episodes of atrial fibrillation without any long-term sequelae for them or their infants.…”

“…Procainamide or quinidine is recommended for use of chemical cardioversion, whereas other medications, including flecainide, also have been used successfully in pregnancy without any adverse sequelae. 4,5 However, some antiarrhythmics are not recommended during pregnancy, such as amiodarone, because of concerns of teratogenicity. If chemical cardioversion is successful, then continued oral antiarrhythmics are unnecessary.…”

New-onset lone atrial fibrillation in pregnancy

“…Incidence of tachyarrhythmias may increase during pregnancy, possibly due to the physiological changes associated with pregnancy. Though atrial fibrillation is the most common arrhythmia, its incidence in pregnancy is rare and if present it usually occurs in patients with congenital heart disease, rheumatic heart disease and other noncardiac conditions such as thyroid and electrolyte abnormalities, medication effects (such as tocolytics) and pulmonary embolism [Walsh et al 2008]. New-onset lone atrial fibrillation in pregnancy is extremely rare and here we report a case of a young pregnant female presented with lone atrial fibrillation without hemodynamic compromise who responded well to intravenous diltiazem.…”
