ABSTRACT:
An apparatus for validating a non-invasively obtained estimate of LVEDP includes a non-invasive system for non-invasively obtaining a first estimate of the LVEDP; an invasive system for invasively obtaining a second estimate of the LVEDP concurrent with the first estimate; and a processor for comparing the first and second estimates of the LVEDP.
