Acute ascending aortic dissection due to transcatheter patent ductus arteriosus closure in the elderly: An extremely rare complication of transcatheter patent ductus arteriosus closure

A 68-year-old woman with a PDA with focal calcification at the aortic orifice of the ampulla with a minimum diameter of 4.0 mm and length of 14.8 mm, was treated with a 10/8-mm Amplatzer duct occluder (ADO) (St. Jude Medical Corp, St. Paul, MN, USA). After device implantation, systolic blood pressure (BP) increased to approximately 220 mmHg from 130 mmHg. She experienced transient dyspnea from hypertensive heart failure, which improved through continuous infusion of anti-hypertensive agents. She suddenly felt pressure on her chest 12 h post-procedure and collapsed. Surgical thoracotomy revealed an ascending aortic dissection into the pericardial space. In retrospective review, the ADO may have been slightly deformed by fluoroscopy. The complication may have been triggered by the resilience caused by device deformation, damage to the aortic wall due to the aortic side of the device, uneven elasticity of the arterial wall, and uncontrolled excessively high blood pressure.<Learning objective: Although transcatheter patent ductus arteriosus (PDA) closure is an established, safe, and effective procedure when treating PD...
