“…Initially, CTI block for patients with DTGA after Senning or Mustard operation was assessed using a previously proposed method consisting of a multipolar catheter in the systemic venous atrium (SVA). 12 Later, the multipolar catheter was placed directly within the PVA for detailed assessment of bidirectional block in these patients. Isthmus block for other forms of IART was tested whenever possible but was not required.…”

“…Proving CTI-dependence during the electrophysiology study prior to CTI ablation can be done one of two ways: by accurately mapping the entire AFL cycle length in the pulmonary venous side, or by entraining the isthmus (Fig. 6) [7,14,17,18]. In-circuit timing with CTI entrainment is determined in the usual fashion, by showing a post pacing or first return cycle length identical or nearly identical to the tachycardia cycle length.…”

“…Early canine models of the Mustard-Senning procedure demonstrated not only a higher incidence of IART postoperatively, but also that these reentrant circuits were divided into four categories: CTI-dependent loop around the tricuspid valve, periatriotomy, in a pathway involving both the atria, or around the mitral valve [15]. Since the initial canine study in 1987, these findings have been confirmed in humans, and the most common form of IART encountered in patients after a Mustard-Senning repair is a circuit that moves around the tricuspid valve (TV) in a CTI-dependent manner, identical in nature to typical AFL, except for lying on the other side of the systemic venous baffle [16,17].…”

Purpose of reviewThe adult congenital heart patient population is rapidly growing due to increasing survival rates, and they often face chronic physiologic challenges as sequalae of both their defects and repairs. Among the most common sequalae are arrhythmias. Here we describe intra-atrial reentrant tachycardia (IART), one of the most commonly seen arrhythmias in the adult congenital heart population, and the approaches to successful ablation in adult congenital heart patients. Recent findingsIART has increasing ablation success rates due to the increasing exposure of electrophysiologists to congenital cases, advances in technology, and the increasing application of both our pediatric congenital knowledge and adult acquired knowledge to the adult congenital population. SummaryIART is a frequently seen arrhythmia in the adult congenital population, and it can have life-threatening consequences in the setting of congenital disease. Ablation techniques and treatment rates have improved over time, despite the challenges these cases present to clinicians; success of the ablation depends on careful, often creative, preplanning, and understanding of the complex individualized anatomy and circuits of the patient.

In children and adolescents with congenital heart disease (CHD) tachyarrhythmia occurs more frequently compared to patients with otherwise normal hearts. Arrhythmia substrates may be a natural part of certain congenital cardiac malformations or may result from long lasting myocardial deterioration as a result of CHD and/or cardiac surgery. Treatment of tachycardia is more frequently required even in early childhood, as the impact on quality of life, morbidity and mortality is higher due to an often reduced hemodynamic tolerance. Over the past 20 years interventional electrophysiology has been established as the therapy of choice for the majority of chronic or chronically recurrent tachycardia even in children with CHD. The success and risks of treatment are predominantly influenced by the individual expression of the cardiac anomaly and, if surgery has been performed, the highly variant postoperative anatomy. Introduction of 3D electroanatomical mapping systems together with modern cardiac imaging tools have significantly contributed to an improved understanding, particularly in postoperative tachycardia. Despite such progress, success rates are lower and recurrences are more frequent compared to patients without CHD. Complex and often multiple tachycardia courses account for the still limited performance as well as a frequently insufficient lesion formation with the use of radiofrequency current in the hypertrophic and fibrotic myocardium. Electrophysiology in children and adolescents, particularly if CHD is present, represents a highly specialized discipline requiring a high expertise in CHD, CHD surgery and cardiac electrophysiology and is ideally imbedded within an interdisciplinary cardiological and cardiosurgical setting.
