“…Though complete LA mapping was not feasible, a senior operator could reach the left interatrial septum via a transaortic approach with satisfactory catheter contact and stability. This retrograde approach has been successfully adopted in previous reports, 5 but hemodynamic consequences might occur with simultaneous catheter crossing through the aortic and mitral valves. Moreover, caution should be taken since excessive catheter manipulation or looping using this unusual approach might damage the aortic or mitral valve apparatus.…”

Catheter ablation (CA) of left atrial tachycardia adjacent to implanted septal closure devices represents a multifaceted challenge. We describe the case of a 57‐year‐old patient with remote percutaneous closure of atrial septal defect who underwent successful CA of left atrial tachycardia adjacent to the septal device using a transaortic approach and RF energy. Besides the technical difficulties and associated risks, interference between the device and applied RF parameters may limit ablation efficiency. Further research is required to evaluate the safety, efficacy, and optimal energy type/parameters when ablating arrhythmias adjacent to these devices.

“…6,7 However, this system can be used in only limited institutions. Recently, Comandante et al 8 reported the first case of atrial fibrillation ablation through a retrograde approach with conventional irrigating ablation catheter and 3D electroanatomic mapping. To stabilize the catheter position and to facilitate approachability to all parts of the LA, they used a large curve catheter to form a loop.…”

IntroductionIn patients with prior atrial septal defect (ASD) closure and atrial tachyarrhythmias, transseptal puncture can be challenging.Methods and ResultsThis case report discusses a 65‐year‐old man who had previously undergone pulmonary vein isolation (PVI) and cavo‐tricuspid isthmus ablation for atrial fibrillation before ASD closure, respectively. He developed atrial tachycardia (AT) and underwent catheter ablation. AT was diagnosed as peri‐mitral flutter and the mitral isthmus (MI) linear ablation via a trans‐aortic approach successfully terminated it.ConclusionThis case demonstrates the feasibility and safety of transaortic MI linear ablation in patients with ASD closure devices or anatomical challenges when transseptal puncture is difficult.

Radiofrequency catheter ablation (RFCA) is a cornerstone treatment of atrial fibrillation (AF). Transfemoral venous approach with transseptal puncture to assess left atrium (LA) is a mainstream method for AF ablation. Interrupted inferior vena cava (IVC) is a rare congenital vascular anomaly which complicates electrophysiologic procedures and makes conventional approach not feasible. According to previous literature, trans-jugular and transhepatic approach were two alternative methods to achieve AF ablation. Difficulty in transseptal puncture and bleeding risk were still the major concern of these alternative approach. This report presents a 55-year-old female with an incidental finding of interrupted IVC during AF ablation. Retrograde aortic approach was applied to assess LA for RFCA according to our previous experience. Circumferential pulmonary vein isolation was achieved and confirmed by absence of pulmonary vein potentials using the ablation catheter. After the procedure, no adverse events were observed. Neither recurrence of atrial tachyarrhythmia nor valvular injury was observed during oneyear follow-up period.A 55-year-old female patient was referred to our cardiovascular clinic from primary care hospital for propafenone refractory paroxysmal AF for two years. Because of intolerable symptoms, RFCA was suggested. The hemogram, comprehensive biochemical panel, and thyroid function test were reported normal. The echocardiogram revealed normal left ventricular systolic function without structural heart disease. After careful discussion of
