Summary: Catheter-based slow-pathway modification (SPM) is an effective and safe treatment for symptomatic atrioventricular nodal reentrant tachycardia (AVNRT) in pediatric patients. Radiofrequency energy is commonly used. Patient age does not significantly affect the treatment outcome.

Summary: AF-CA in patients with situs inversus dextrocardia can be challenging due to contrary anatomy. Improved procedures and ablation strategies can ensure successful procedures, but long-term outcomes may not be favorable, indicating the need for further optimization in treatment strategies.

Summary: The feasibility, effectiveness, and safety of zero-fluoroscopy radiofrequency and cryoablation for different types of supraventricular tachycardias in pediatric patients were retrospectively analyzed. The results showed that this approach achieved excellent treatment outcomes while eliminating the harmful effects of radiation.

Summary: The study suggests that radiofrequency catheter ablation of supraventricular tachycardia in patients with pulmonary hypertension is feasible and has a good long-term success rate. Cavotricuspid isthmus-independent atrial flutter and a wider pulmonary artery diameter may increase the risk for ablation failure.

Summary: This paper summarizes the efficacy and safety of performing the CMP-IV procedure concomitantly with valvular surgery in patients with situs inversus dextrocardia. The results show that CMP-IV is a safe and effective method for eliminating AF in these patients, with no recurrence or complications observed.

Summary: A 70-year-old woman with situs inversus totalis underwent catheter ablation for atrial fibrillation and atrial flutter. Multiple atrial tachycardias with complex anatomy were successfully treated using a three-dimensional electroanatomic mapping system. The presence of fragmented potentials in a limited area of the anterior morphologic left atrium and small-circuit reentry with extremely slow conduction were key factors in the treatment success.

Summary: A 70-year-old female with DSI and inferior vena cava occlusion underwent successful pulmonary vein isolation for symptomatic AF, but experienced recurrence of AF and symptomatic bradycardia, leading to the implantation of a pacemaker. This case presents a rare congenital abnormality managed with these interventions without complications.

Summary: This study found that with increasing age, both typical and atypical forms of AVNRT increased while AVRT decreased. Female sex predominance in AVNRT was not observed in older patients. Despite a longer tachycardia cycle length, patients became more symptomatic with age, but catheter ablation outcomes and complications were not associated with age.

Summary: The study found that age, chest discomfort during SVT, and the number of antiarrhythmic drugs used before CA were predictors of non-referral for CA as a first-line treatment in SVT patients.

Summary: This case report demonstrates a safe and effective atrial fibrillation ablation guided by the robotic magnetic navigation system in combination with intracardiac echocardiography in a patient with dextrocardia with situs inversus. The use of magnetic catheter for three-dimensional reconstruction and fusion with pre-acquired CT images allowed for complete pulmonary vein isolation. The combination of these technologies reduces the risk of complications and facilitates treatment of patients with complex anatomy.

Summary: Dextrocardia is a rare congenital cardiac positional anomaly that requires special consideration of heart and surgeon positions during surgery. In this case, a 74-year-old woman was referred for aortic regurgitation and underwent aortic valve replacement surgery.

Summary: This study compared the safety and effectiveness of the Jinjiang and J&J catheters for radiofrequency ablation of PSVT. The results showed that there were no significant differences between the two catheters in terms of success rate, ablation time, frequency of ablation, complications, and recurrence.

Summary: This study aimed to identify the electrophysiological characteristics of atrial tachycardia (AT) recurrence in adults with congenital heart disease (ACHD). The results showed that repeat ATs in ACHD patients were more frequently focal, required isoproterenol administration, or involved intra-atrial reentrant tachycardia within the pulmonary venous atrium or atrial septum. Partial success, index pulmonary venous atrium substrate, and a remote history of atrial fibrillation were negative factors associated with AT/AF recurrence.
