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.

Progressive dyspnea and hypoxaemia in the subacute phase after transcatheter aortic valve implantation (TAVI) are uncommon and warrant immediate assessment of valve and prosthesis leaflet function to exclude thrombosis, as well as investigation for other causes related to the procedure, such as left ventricular dysfunction, pulmonary embolism, and respiratory sepsis. In this case, we report the observation of a patient presenting two weeks after TAVI with arterial hypoxaemia in an upright position, relieved by lying flat, and coupled with an intracardiac shunt detected on echocardiography in the absence of pulmonary hypertension, raising the suspicion of Platypnea-Orthodeoxia Syndrome (POS). Invasive intracardiac haemodynamic assessment showed a significant right-to-left shunt (Qp/Qs = 0.74), which confirmed the diagnosis, with subsequent closure of the intracardiac defect resulting in immediate relief of symptoms and hypoxaemia. To our knowledge, this is the first reported case of an interatrial defect and shunt causing Platypnea-Orthodeoxia Syndrome after transcatheter aortic valve implantation, resolved by percutaneous device closure.

During transcatheter aortic valve replacement with a self-expanding prosthesis, prosthesis embolization represents a rare but severe complication. Etiologies of prosthesis embolization include improper sizing and malpositioning, specifically high deployment with respect to the aortic annulus. Treatment of embolization into the aorta relies upon repositioning of the prosthesis using endovascular snares or removal with open surgery. Patients with prosthesis embolization have a high risk of mortality and morbidity including stroke and aortic dissection associated with manipulation of the prosthesis in the ascending aorta. We describe a case of self-expanding prosthesis embolization and present a solution using a second prosthesis to capture the embolized one.
