Submitral left ventricular aneurysm following TAVR-in-TAVR
Imaging findings
Cardiac CTA in a patient who underwent a TAVR-in-TAVR (valve-in-valve) procedure for recurrent aortic stenosis reveals a large aneurysm arising from the left ventricular free wall at the base (submitral LV aneurysm/pseudoaneurysm), showing thick walls with peripheral low attenuation, likely due to ischemic injury from graft occlusion or direct guidewire trauma.
Key takeaways
Submitral left ventricular aneurysms or pseudoaneurysms are rare complications of transcatheter aortic valve procedures. They can arise from mechanical injury to the LV free wall by guidewires or catheters, or from localized myocardial infarction.
