Chung, Charles ; Kovacs, Sandor ; Shmuylovich, Leonid
T-005426

— Technology Description Researchers in Prof. Sandor Kovacs’ laboratory developed a patented, non-invasive, load-independent method to measure the intrinsic diastolic performance of the heart. This load-independent index of filling (LIIF) can be incorporated into the software of echocardiogram…

Chung, Charles ; Kovacs, Sandor ; Shmuylovich, Leonid ; Zhang, Weixiong
T-007562

— Technology Description Researchers in the Cardiovascular Biophysics Laboratory at Washington University developed a patented, real-time, automated index to reliably detect delayed relaxation during cardiac catheterization diagnostics. This technique, called pressure recovery ratio (PRR), serves as…
