Why the study?
Prosthesis-patient mismatch following aortic valve replacement is a form of LVOT obstruction that is likely underestimated and undertreated.
The Konno anterior aorto-ventriculoplasty is presented as a surgical approach for treating prosthesis-patient mismatch in adults.
May inform surgical decisions in select adult prosthesis-patient mismatch cases; leaves open need for prospective validation.
BACKGROUND: The most common forms of congenital and acquired obstruction of the left ventricular outflow tract (LVOT) are valvular aortic stenosis, congenital tunnel-like obstruction, hypertrophic obstructive cardiomyopathy and, finally, the prosthesis-patient mismatch (PPM) following aortic valve replacement. The last is most probably underestimated and undertreated. Here, we report our experience with the Konno anterior aorto-ventriculoplasty in adult patients suffering from prothesis-patient mismatch.
