Noninvasive Characterization of Intra-Atrial Reentrant Tachyarrhythmias After Surgical Repair of Congenital Heart Diseases

Clinical Efficacy of Dofetilide for the Treatment of Atrial Tachyarrhythmias in Adults with Congenital Heart Disease

“…We evaluated all patients with CHD that were admitted to our institution for initiation of D for the treatment of AT. Patients were classified as having persistent vs. paroxysmal AF, AFL, or atrial tachycardia according to electrocardiographic and clinical criteria . All ATs lasting more than 7 days were classified as persistent, regardless of the suspected mechanism.…”

“…Patients were classified as having persistent vs. paroxysmal AF, AFL, or atrial tachycardia according to electrocardiographic and clinical criteria. 12,16 All ATs lasting more than 7 days were classified as persistent, regardless of the suspected mechanism. D starting dose was chosen and adjusted according the individual's creatinine clearance and corrected QT interval (QTc), following the guidelines established for the DIAMOND trial.…”

Unusual Macro-Reentrant Atrial Flutter Because of Extensive Atrial Myocardial Damage in a Seemingly Structurally Normal Heart

“…Recent advanced 3-D electroanatomical mapping systems (eg, CARTO and the non-contact mapping systems) are very helpful in detecting the magnitude and extent of the underlying myocardial damage by creating a substrate map, clarifying the tachycardia mechanism and circuit by creating activation and propagation maps, and determining the optimal ablation site. [4][5][6][7][8][9] This new method may improve the success rate of electrophysiologically guided and anatomically guided catheter ablation of unusual, focal and macro-reentrant tachycardias, as in this case.…”

A Less Invasive Examination for Atrial Tachycardias After Surgery for Congenital Heart Disease

“…Aiba and colleagues used body surface mapping (BSM) to differentiate these tachycardias before doing a catheter ablation. 6 They demonstrated that BSM combined with the signal-averaged ECG could characterize atrial reentrant tachycardias and differentiate between cavotricuspid isthmus dependent atrial flutter, incisional reentrant tachycardia and double-loop reentry. The determination of the type of atrial tachycardia before the catheter ablation would be beneficial for patients and helpful for physicians.…”
