Two recent articles describing sizing algorithm for
#TAVR
in bicuspid aortic valves (
#BAV
) agree that annular measurements are valid:

Technique for identifying annulus non-raphe-type BAV.
Vena contracta (VC): point in a fluid stream where the diameter of the stream is least & fluid velocity is max. Fluid streamlines follow a smooth path, converge just downstream from opening resulting in narrowing of the jet.

PISA measures EROA of VC.

Evolut Low Risk 4-yr results better for TAVR than SAVR! What will 5-yr results show for all-cause mortality? According to Dr. Reardon, 7-10-yr followup will help determine outcomes and durability.

Two new studies confirming the staging system proposed for Aortic Stenosis is independently associated with all-cause mortality in both Symptomatic and Asymptomatic pts.

New review focuses on the relationship of the right atrioventricular axis, TV, and pulmonary vascular system and how structural and hemodynamic alterations determine the mechanism of TR.

NOTION randomized data comparing durability for
#TAVR
& SAVR, low risk pts. 6 yr all-cause mortality similar but TAVR less Structural Valve Dysfx (SVD). Significant limitations of study but good news for now!

Great tutorial of proper measurement of LVOT for accurate calculation of LV stroke volume—even more important to measure at the annulus in Non-AS valves. See PDF of our editorial to guideline.

Can't see 2 identical-appearing cusps in long axis and be in true center of a valve that has 3 cusps. Once squared, major error in LVOT area and subsequent AVA and EOA. Note formula for predicted LVOT by BSA. Also, post TAVR new-LVOT measured from outer to outer stent frame.
