Percutaneous closure of complex paravalvular aortic root pseudoaneurysm and aorta-cavitary fistulas

Percutaneous device closure of a large complex aortic root pseudoaneurysm

Pseudoaneurysm of the aorta is a rare and high-risk complication of native aortic valve endocarditis and can develop following cardiac surgery for aortic valve and root disease. If left untreated, there is a significant risk of aortic wall rupture and fatality. Given the high risk of mortality associated with traditional open surgical repair of aortic pseudoaneurysms, endovascular approach is a potentially favourable alternative. We describe a unique case of a young woman with a large and complex paraprosthetic pseudoaneurysm with multiple communicating fistulae which was successfully percutaneously treated with two occluder devices. In this technically challenging case, a minor but unique procedural complication is also illustrated.

Endovascular Closure of 2 Subannular Pseudoaneurysms of the Aortic Root After Surgical Aortic Valve Replacement

A 68-year-old woman was initially admitted with 2 subannular pseudoaneurysms of the aortic root after aortic valve replacement. The aneurysm expanded after 10 days and was treated using endovascular closure devices. (Level of Difficulty: Advanced.)

Transesophageal echocardiographic guidance for percutaneous closure of aortic pseudoaneurysm using a type II Amplatzer vascular plug: a case report

Aortic pseudoaneurysm after cardiac surgery is a rare entity, but it is potentially fatal due to its clinical course along with higher morbidity and mortality rates. Instead of open surgical repair, percutaneous procedures have been introduced as other options for managing an aortic pseudoaneurysm. In this case report, we describe transesophageal echocardiography guidance for successful percutaneous closure of an aortic pseudoaneurysm located in the left ventricular outflow tract by using a type II Amplatzer vascular plug in a patient in whom open surgical repair was not recommended.
