What are the limitations of echocardiographic short-axis assessment of paravalvular leakage after CoreValve TAVI?
Echocardiographic short-axis assessment of paravalvular leakage after TAVI has inherent limitations that can lead to misclassification of severity, challenging the strict application of VARC criteria.
To make assessment of paravalvular aortic leakage (PVL) after transcatheter aortic valve implantation (TAVI) more uniform the second Valve Academic Research Consortium (VARC) recently updated the echocardiographic criteria for mild, moderate and severe PVL. In the VARC recommendation the assessment of the circumferential extent of PVL in the short-axis view is considered critical. In this paper we will discuss our observational data on the limitations and difficulties of this particular view, that may potentially result in overestimation or underestimation of PVL severity.
Geleijnse et al. (Tue,) conducted a observational in Severe aortic stenosis post-TAVI (n=554). CoreValve Revalving System (TAVI) was evaluated on False negative parasternal short-axis imaging for paravalvular leakage. Parasternal short-axis echocardiographic assessment of paravalvular leakage after CoreValve transcatheter aortic valve implantation is limited by a 14% false negative rate.
