[...]. Perimembranous Ventricular Septal Defect as a Transcatheter Aortic Valve Implantation (TAVI) Complication. CTICases. Published September 20, 2014. https://str-case-explorer.pages.dev/c/45ur8
Imaging findings
Pre-operative CT shows no ventricular septal defect (VSD), but some asymmetric calcification of the mitral-aortic curtain. Post-operative CT following TAVI reveals a new small perimembranous VSD located directly below the implanted TAVI valve.
Key takeaways
A perimembranous VSD is a rare, but reported, complication of TAVI, presumed to be created during the procedure. Proposed mechanisms include over-inflation/over-dilation of the valve, increased calcium effect, or wire injury. It should be considered if patients develop worsening heart failure symptoms after TAVI.
