Transcatheter Repair of Iatrogenic Aortic Perforation Complicating Transseptal Puncture for a Catheter Ablation of Atrial Arrhythmia
並列摘要
Aortic root perforation is a potentially life-threatening complication that may occur during transseptal puncture and requires immediate repair. We present a 71-year-old man who was admitted for catheter ablation of persistent atypical atrial flutter. Fluoroscopic-guided transseptal puncture was performed to gain access to the left atrium. An unrecognized puncture of the aortic root by Brockenbrough needle and inadvertent advancement of Mullins sheath resulted in aortic root perforation. We decided to seal the hole transcatheterly with an occlude device. Severe aortic regurgitation (AR) was noted by transesophageal echocardiography after deployment of a 6 mm Amplatzer septal occluder (ASO). Thereafter, we switched to a 6/4-mm Amplatzer duct occluder (ADO) and only minimal AR was noted after deployment. This is because the diameter of the left atrial disc of ASO is larger than the diameter of the retention skirt of ADO to interfere with the movement of aortic valve leaflet. During 6 months of echocardiographic follow-up, the ADO remained in place and no residual shunt was observed.
