AI Article Synopsis
- This case report details the successful treatment of an accessory pathway related to a surgical procedure in a 15-year-old girl with tricuspid atresia who had undergone a Fontan operation.
- Using electro-anatomic mapping, doctors identified the problem area linked to her supraventricular tachycardia and effectively performed radiofrequency ablation to correct it.
- The report also discusses previous cases of abnormal heart conduction after similar surgeries and underscores the importance of advanced mapping techniques for diagnosing complex heart rhythm issues in patients with congenital heart defects.
Article Abstract
This case report describes the successful ablation of an iatrogenic accessory pathway in a Fontan patient. A 15-year-old girl with tricuspid atresia was palliated with a Bjork modification Fontan procedure; six years later she developed supraventricular tachycardia. Electro-anatomic mapping during electrophysiology study localized a concealed iatrogenic atrioventricular accessory pathway and facilitated successful ablation using radiofrequency energy. This report reviews the reported cases of anomalous atrioventricular conduction (antegrade only, retrograde only [Hager, et al., 2005;130:48-53], both [Liberman, et al., 2000;23:914-6]) after the Fontan/Bjork repair, outlines a potential pathophysiologic mechanism for the post-operative tachyarrhythmia and highlights the usefulness of electro-anatomic mapping in identifying unusual arrhythmias in post-operative patients with complex congenital heart disease.

Quest for the ideal assessment of electrical ventricular dyssynchrony in cardiac resynchronization therapy.

This paper reviews the literature on assessing electrical dyssynchrony for patient selection in cardiac resynchronization therapy (CRT). The guideline-recommended electrocardiographic (ECG) criteria for CRT are QRS duration and morphology, established through inclusion criteria in large CRT trials. However, both QRS duration and LBBB morphology have their shortcomings.

Article Synopsis
- Atrial flutter is a heart condition that can lead to serious health issues, typically treated with medications, while more persistent cases may require ablation, a procedure that can have risks including complete heart block.* -
- A case involving a 73-year-old woman highlighted complications during ablation for atrial flutter when a heart block occurred due to catheter positioning too close to the His bundle—a critical area for heart electrical signals.* -
- The patient recovered quickly after the block but later needed a pacemaker due to severe bradycardia, emphasizing the need for careful catheter placement during ablation to avoid such complications.*
Background: The R wave in lead aVR, during the wide QRS complex tachycardia, is commonly observed in a ventricular tachycardia (VT) arising from certain locations in the ventricles.
Objectives: This was a retrospective and a proof of concept study to correlate the sites of origin of VT and premature ventricular contractions (PVCs) with the occurrence of R wave in lead aVR.
Methods: Patients with VT or high density of PVCs were included.
