Visualization of an Accessory Pathway by 3D High-Density Mapping: A Case of Ebstein Anomaly With Atrioventricular Re-entrant Tachycardia.

ABSTRACT: Radiofrequency catheter ablation (RFCA) is the primary choice for treating patients with an accessory pathway and atrioventricular re-entrant tachycardia. However, using RFCA to treat a right-sided accessory pathway in a patient with Ebstein anomaly can be difficult owing to challenges in locating the electrophysiological atrioventricular groove. We report a case of atrioventricular re-entrant tachycardia in a patient with Ebstein anomaly and a right-sided accessory pathway that was successfully treated using RFCA and 3-dimensional (3D) high-density mapping. RFCA and 3D mapping may be useful in the management of such cases and may aid in improving prognoses of patients.

Dual Atrioventricular Nodal Non–Re-Entrant Tachycardia

Project description:A patient presented with symptoms of palpitations. Her standard 12-lead electrocardiogram captured 3 potential causes of her symptoms (premature atrial contractions, junctional rhythm, and narrow complex tachycardia). Further workup uncovered dual atrioventricular node physiology with 1:2 sinus conduction and resultant alternating QRS from a slow and fast conduction pathway. (Level of Difficulty: Intermediate.)

Severe Heart Failure Associated With Tachycardia-Induced Cardiomyopathy Due to Incessant Atrioventricular Re-Entrant Tachycardia.

Project description:Short RP interval atrioventricular re-entrant tachycardias do not typically present as an incessant form. We present 2 cases of incessant atrioventricular re-entrant tachycardias leading to tachycardia-induced cardiomyopathy with severe heart failure presentation in middle-aged adults. Both underwent accessory pathway ablation and recovered normal left ventricle function before hospital discharge. (Level of Difficulty: Intermediate.).

Myocardial Infarction by a Myocardial Bridge in the LAD Combined With Atrioventricular Re-Entrant Supraventricular Tachycardia

Project description:We present the case of a patient who presented with palpitations and was found to have atrioventricular re-entrant tachycardia with unusually elevated cardiac biomarkers. A coronary computed tomographic angiography showed a myocardial left anterior descending artery bridge; an accessory pathway was ablated, and cardiac magnetic resonance revealed anteroseptal myocardial infarction resulting from hypoperfusion during tachycardia caused by the left anterior descending artery myocardial bridge.

Open window mapping for redo accessory pathway ablation in Ebstein anomaly.

Project description:Accessory pathway ablation in Ebstein anomaly can be significantly more challenging than in structurally normal hearts. An alternative to the conventional approach to mapping APs is to detect points with a high-density mapping catheter based on an automated detection algorithm using open window mapping. It detects the sharpest signal at each point with high-density mapping rather than relying on the origin of the local electrogram to localize the pathway and determine a site for successful ablation. We herein report the first case in literature of a redo-accessory pathway ablation in Ebstein anomaly using this technique.

Atypical twin atrioventricular nodal re-entrant tachycardia in a congenitally corrected transposition of the great arteries patient with a surgical repair of a ventricular septal defect: a case report.

Project description:BackgroundTwin atrioventricular (AV) nodal tachycardia is a rare mechanism of supraventricular arrhythmia, only seen in some specific congenital heart defects (CHD). It consists of a re-entrant circuit between two distinct AV nodes (anterior and inferior). Since both nodes have antegrade and retrograde conduction, there is usually two QRS morphologies in sinus rhythm.Case summaryThis case is about an atypical twin AV nodal tachycardia in a 15 years old patient with congenitally corrected transposition of the great arteries and previous history of a ventricular septal defect repair. The surgical closure was probably responsible of a poor antegrade conduction over the inferior AV node, which was responsible for a unique QRS morphology. He finally received a catheter ablation of the inferior AV node. He remained asymptomatic without anti-arrhythmic drugs at 8-months post-ablation.DiscussionTwin AV nodal re-entrant tachycardia is a rare phenomenon. The presentation and electrophysiological study can be both atypical due to previous surgical repair. The operator should be aware of specific CHD where twin AV nodal re-entrant tachycardias are expected.
