Standardized Invasive Hemodynamics for Elevated Gradients Post TAVR
Standardized Invasive Hemodynamics for Elevated Gradients Post TAVR
The DISCORDANCE TAVR study will determine the discordance between echocardiography-derived
 and invasive transaortic gradients, as determined by a consistent and reproducible technique
 (Standardized Invasive Hemodynamics) post-TAVR.
Inclusion Criteria:

 -  Echocardiographic transaortic mean gradient ≥ 20mmHg OR VARC-3 criteria for ≥ moderate
 hemodynamic valve deterioration post TAVR on any TTE > 1 month post-TAVR

 -  Consensus by the Heart Team that the patient is suitable for Standardized Invasive
 Hemodynamics (SIH).

 Exclusion Criteria:

 -  CT demonstrating leaflet thrombosis or hypoattenuated leaflet thickening (HALT)
