“…Although there are definitions such as right atrial, left atrial, biatrial, and mini-maze, they are all considered as a maze procedure. 13 Surgical maze procedures began to be performed and popularised for the treatment of atrial arrhythmias in congenital heart surgery over time. [14][15][16][17] Apart from therapeutic use, it is also used in prophylactic purposes for the prevention of late arrhythmias in experienced centres.…”

“…The thickness of their atriums varies according to the underlying cardiac pathology, such as a thick atrial wall in tricuspid atresia and thin atrial wall in double inlet left ventricle. 13 In cases where the atrium is thick, ablation time can be extended to affect full thickness. In our study population, ablation was mostly performed for 140 seconds.…”

Objectives: This study aimed to evaluate the early outcomes of patients who underwent a concomitant therapeutic maze procedure for congenital heart surgery. Materials and Methods: Between 2019 and 2020, eight patients underwent surgical cryoablation by using the same type of cryoablation probe. Results: Three patients had atrial flutter, two had Wolf–Parkinson–White syndrome, two intra-atrial reentrant tachycardia, and one had atrial fibrillation. Four patients underwent electrophysiological study. Preoperatively, one patient was on 3, two were on 2, five were on 1 antiarrhythmic drug. Six patients underwent right atrial maze and two underwent bilateral atrial maze. Five out of six right atrial maze patients underwent right atrial reduction. Nine different lesion sets were used. Some of the lesions were combined and applied as one lesion. In Ebstein’s anomaly patients, the lesion from coronary sinus to displaced tricuspid annulus was delicately performed. The single ventricle patient with heterotaxy had junctional rhythm at the time of discharge and was the only patient who experienced atrial extrasystoles 2 months after discharge. Seven of the eight patients were on sinus rhythm. No patient needed permanent pacemaker placement. Conclusion: Cryomaze procedure can be applied in congenital heart diseases with acceptable arrhythmia-free rates by selecting the appropriate materials and suitable lesion sets. The application of cryomaze in heterotaxy patients can be challenging due to differences in the conduction system and complex anatomy. Consensus with the electrophysiology team about the choice of the right–left or biatrial maze procedure is mandatory for operational success.

“…A significant number of reports describe the efficacy and long-term results of intraoperative surgical ablation of Afib during corrective procedures for EA in pediatric and adult populations [5,6,10]. 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].…”

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.

“…), surgical interventions may become necessary for regurgitation across the atrioventricular/aortic valve and for stenosis/thrombosis of the Fontan pathway (from the vena cava to the pulmonary artery). [126][127][128][129][130] These are mechanical factors that elevate CVP.…”

CT precisely illustrates abnormal origins and courses of the coronary arteries in many cases, which is why coronary angiography is not recommended as a routine examination (Class III). In some patients, nonetheless, coronary angiography is quite informative beyond CT resolution; for example, anastomotic stenosis at the coronary arterial origin would be better demonstrated by catheter angiography after the arterial switch procedure. 174 ▋ 3.4.5 Endomyocardial Biopsy Endomyocardial biopsy is rarely required in patients with postoperative CHD. ▋ 3.4.6 Catheter InterventionTranscatheter closure of atrial septal defect or patent ductus arteriosus is carried out routinely in the cardiac catheterization room, as is percutaneous pulmonary angioplasty. Interventional closure of ventricular septal defect needs more evidence before becoming established in Japan.Transcatheter pulmonary valve replacement will be introduced in the near future.Electrophysiological study and catheter ablation are common practices for arrhythmias in the CHD field. Recent advances in technology and devices, such as 3D mapping systems, have contributed to notable results in anti-arrythmic treatments in patients with repaired CHD. 175
