Abstract Background  Automaticity is the dominant mechanism in maternal focal atrial tachycardia (FAT) during pregnancy and if incessant, can cause tachycardia-induced cardiomyopathy. Medication failure for FATs is common, however, for the subgroup due to increased automaticity ivabradine sensitivity has been described and may represent a valuable treatment option. Little data are available regarding the safety profile of ivabradine during pregnancy. Case Summary  We report the case of a 38-year-old woman with background of peripartum cardiomyopathy and incessant atrial tachycardia with deteriorating ventricular function during her second pregnancy unresponsive to betablockade and demonstrating the immediate successful rate-controlling effect of ivabradine. Discussion  Early recognition of persistent maternal FAT is essential due to its frequent association with tachycardia-mediated cardiomyopathy. Our case report highlights the challenges of providing an equally safe and effective treatment of these notoriously difficult to treat arrhythmias during pregnancy. Ivabradine in combination with a betablocker can be effective for abnormal automaticity but its safety profile during pregnancy remains uncertain.

Abstract Background Congenital aneurysms of the atrium are very rare malformations. Known complications are therapy-resistant arrhythmias. Different treatments such as medical therapy, electrophysiological ablation, and surgery have been proposed. However, there are no guidelines on treatment. Case summary We describe the case of a neonate with bi-atrial aneurysms causing atrial arrhythmia. Arrhythmia was first observed in the 28th week of gestation. Maternal digoxin treatment did not show any effect. After birth, bi-atrial aneurysms were diagnosed and determined as the probable cause of the atrial tachycardia and later of atrial flutter. Antiarrhythmic drug treatment was initiated. However, only frequency control could be achieved. At the age of 7 months, the patient underwent surgical resection. Since surgery, sinus rhythm is present. Conclusion Atrial aneurysms are rare malformations, known complications are atrial arrhythmia. If medical treatment fails, surgery correction appears to be indicated going along with low operative risk and a high probability of successful termination of arrhythmia.

Reentry Tachycardia

The term permanent junctional reciprocating tachycardia (PJRT) describes an orthodromic atrioventricular reentry tachycardia using a usually concealed slowly conducting accessory pathway with decremental properties as the retrograde limb. The accessory pathway is most commonly located in the posteroseptal region; however, other locations have been described. PJRT is a rare form of supraventricular tachycardia and can be found in all age groups but the majority of affected patients are children and young adults. The 12-lead electrocardiogram during PJRT shows negative P waves in the inferior lead II, III, and aVF, with a long RP interval. Atypical atrioventricular nodal reentry tachycardia and focal atrial tachycardia are important differential diagnoses. Due to the often incessant nature of PJRT, patients may be at risk for tachycardia-induced cardiomyopathy. Whereas pharmacological treatment is often only moderately effective, catheter ablation of the accessory pathway is highly effective with a low complication rate.

Introduction: Occurrence of tachycardias increase during pregnancy in line with the increased propensity to ectopic activity.Case presentation: We present a case of a 30-year-old woman in the 18th week of pregnancy with atrial tachycardia and tachycardia-induced cardiomyopathy that was successfully treated with zero fluoroscopy catheter ablation.Discussion: The described method is safe and efficient and could be used in the future when drug refractory tachycardias occur during pregnancy.

Focal atrial tachycardia (AT) is a relatively uncommon cause of supraventricular tachycardia, but when present is frequently difficult to treat medically. Atrial tachycardias tend to originate from anatomically determined atrial sites. The P-wave morphology on surface electrocardiogram (ECG) together with more sophisticated contemporary mapping techniques facilitates precise localisation and ablation of these ectopic foci. Catheter ablation of focal AT is associated with high long-term success and may be viewed as a primary treatment strategy in symptomatic patients.
