“…A multicenter European study examined the mechanisms and outcomes of catheter ablation in patients with EA and arrhythmias, but did not include patients being treated for Afib [11]. Recent published data from a series of 22 patients with EA undergoing radiofrequency ablation for atrial arrhythmias included 2 EA patients with Afib [12]. …”

Ebstein's anomaly (EA) is a rare congenital heart disease characterized by “atrialization” of the right ventricle, due to apical displacement of the tricuspid leaflets into the right ventricle. Patients with EA may develop all kinds of supraventricular arrhythmias requiring radiofrequency ablation. Atrial fibrillation (Afib) is a common arrhythmia in EA patients, and results in debilitating symptoms that often require surgical treatment. This is a follow-up report of 2 patients with EA undergoing radiofrequency ablation for Afib. The first patient underwent pulmonary vein isolation (PVI) and the ablation of a concomitant atrioventricular nodal reentrant tachycardia. The second patient was also treated with a PVI and a redo PVI 8 months later. Both patients remain in sinus rhythm 8 months on. Radiofrequency ablation is the therapy of choice for patients with pharmacological refractory Afib, but it is not common in patients with EA.

The paper analyzes the experience of catheter treatment of various types of supraventricular arrhythmias in patients with Ebstein’s abnormality (EA) – 19 consecutive cases of the elimination of additional atrioventricular connections (AAVC) and 5 cases of atrial macro-reentry. The elimination of AAVC, just like atrial macroreentry, was preceded by a stage of electrophysiological diagnosis. In a series of observations in 19 patients with EA, 25 AAVC were detected. The article reflects the main electrophysiological differences between “wide” AAVC from multiple ones. In the first procedure, the conduction in all AAVC was eliminated in 16 (84.2%) of 19 patients. 6 of 25 AAVC were qualified by us as “wide”; to eliminate them, a larger number of applications was required – 6 ± 2 (in typical cases – 3 ± 1). In 2 of 3 patients with an unsatisfactory result of the first procedure, AAVC were eliminated during the second procedure. In the long-term period(5.6 ± 3.6 years), recurrences of propagation through AAVC occurred in 2 (10.5%) of 19 patients. All AAVC were permanently eliminated during second procedure. In the group of patients with atrial tachycardia, 3 had a graph characteristic of a typical isthmus-dependent atrial flutter. In one patient with atypical graphics, macro-reentry with excitation circulation around the scar on the anterolateral wall of the right atrium was found. In 3 of 4 patients with isthmus-dependent atrial flutter after radiofrequency exposure, the sinus rhythm was restored and a block of passage through the cavotricuspid isthmus was created. In one case there were changes in the cycle of tachycardia and the morphology of wave P, applying applications between the scar and the tricuspid valve ring led to the creation of a block of passage through this area and to the cessation of arrhythmia. In a patient who initially had reentry with a circulation of excitement around the postoperative scar, arrhythmia was eliminated in a similar way (an additional block was created through the cavotricuspid isthmus). In the observation period of 5.2 ± 2.5 years, there were no recurrences of arrhythmia.

“…Cardiac arrhythmias are an important contributor to many diseases, and have considerable effects on patient morbidity and mortality. Cardiac electrophysiology (EP) studies electrical heart activities, which provides diagnostic and therapeutic strategies including drug therapy, catheter ablation, device implantation, and upgrade/repair/replacement/explant devices for the treatment of heart-rhythm disorders [17][18][19]. In this field, huge amount of data are generated from different HISs and cardiovascular implantable electronic devices (CIEDs) [20,21].…”

Introduction: Cardiac electrophysiology (EP) studies the electrical heart conduction system which is used for diagnosis and treatment of cardiac arrhythmias. In this context, a huge amount of data is generated, requiring efficient and effective access, interpretation, and data analysis from multiple sources in a unified view. To resolve this challenge, this essay presents an ontology to reconcile data heterogeneity problems in this domain.Material and Methods: The cardiac EP ontology was constructed according to the life cycle of ontology building. Structural, functional, and expert evaluation was performed to ensure its quality and usability. Results: Cardiac EP ontology was developed using protégé environment and implemented in OWL editing tool. It presented a detailed hierarchical structure of the cardiac EP domain with around 324 instances describing cardiac EP-related concepts.Conclusion: Cardiac EP ontology provides an explicit formal description of the concepts, relationships, and properties associated with cardiac electrophysiology making seamless data integration between multiple heterogeneous databases. It also is a useful framework for knowledge representation in knowledge-based systems, as well as for explicit communication between experts in the EP domain.

Outcomes of atrial arrhythmia radiofrequency catheter ablation in patients with Ebstein’s anomaly

Abstract: Catheter ablation of atrial arrhythmias in patients with EA has a favorable outcome overall with an acceptable recurrence and safety profile; left-sided ablations are rarely necessary. Despite prior Maze and catheter ablation procedures, CTI-AFl and IART recurrences predominate.
