Imaging findings
Contrast-enhanced chest CT demonstrates a lobulated pseudoaneurysm at the left ventricular apex with communication to the ventricular lumen, located near displaced surgical pledgets from a prior transapical TAVR site. Active contrast extravasation and accumulation are noted within the small apical aneurymsal sac.
Key takeaways
Apical pseudoaneurysm is a known mechanical complication of transapical access for transcatheter aortic valve replacement, often marked by the displacement or disruption of apical surgical closure pledgets. These pseudoaneurysms can be successfully treated with less invasive approaches, such as the percutaneous placement of an endovascular ventricular septal defect occluding device.
