PathWays Case Study for April 26
A 90-year-old man with symptomatic severe aortic stenosis underwent elective percutaneous (transcatheter) native aortic valve replacement with a bovine bioprosthetic valve. Immediately following the procedure, the patient became hemodynamically unstable, developed a large femoral hematoma at the site of catheterization, and a large prosthetic valve mass was noted on echocardiogram. Despite supportive measures, the patient continued to deteriorate and expired approximately 12 hours following the procedure. An autopsy was performed.
