An 82-year-old man with a past medical history of a
27 mm Mosaic porcine xenograft aortic valve placed
10 years ago for degenerative aortic stenosis was
admitted for acute heart failure. Diagnostic work up
revealed a degenerated surgical aortic valve (SAV)
with severe regurgitation. Due to the patient’s
prohibitive operative risk for open redo surgical aortic
valve replacement (STS 10.4% þ 5% incrementals),
the heart team referred the patient for transcatheter
aortic valve replacement. The patient’s 27 mm Mosaic
aortic valve has a true inner diameter—encompassing
the leaflet tissue mounted within the stent—of
22 mm and therefore would accommodate a 26 mm
CoreValve.
During initial implantation, the CoreValve was
positioned too high resulting in significant perivalvular
leak (Fig. 1A and B). The valve was removed prior to
full deployment; however, during removal, a leaflet of
the patient’s SAV was avulsed. Transesophageal
echocardiography showed severe aortic regurgitation
(Fig. 2). The leaflet was retrieved along with the initial
CoreValve (Fig. 3), and a second CoreValve was
deployed deeper with satisfactory position and
minimal perivalvular leak. Positioning was confirmed
by echocardiography, root angiography, and hemody-
namic assessment.
Surprisingly, there was little hemodynamic
change during the interval between the first and
second CoreValve implants with LVEDP remaining
approximately 20 mmHg (Fig. 4A–C). A possible
explanation could be the patient’s chronic severe aortic
regurgitation preconditioning the left ventricle for
volume overload and higher diastolic pressure.
Though there have been case reports of aortic valve
leaflet avulsion as a consequence of routine coronary
angiography
1
as well as with balloon valvuloplasty,
2
this is the first case of SAV leaflet avulsion during
transaortic valve replacement.
