Value of CT

Pre-CT adoption is rising

Pre-CT use is expected to double among WATCHMAN Implanters.
A majority of these Implanters want to be involved in the CT analysis themselves.

Top three advantages of pre-CT according to WATCHMAN Implanters1

Better patient experience

physician and patient

Better understanding of anatomy

heart anatomy

Increased procedural efficiency

Procedure benefits of pre-CT

Each LAA is unique, and CT reveals a complete picture of the anatomy to make your procedures more predictable. 

Benefits of pre-CT shown by Henry Ford Hospital2

100% Procedural Success with 3D-CT vs 92% with 2D-TEE
25% Lower Procedure Time with 3D-CT vs 2D-TEE
"Pre-procedural cardiac CT may improve the accuracy, efficacy and safety of LAAO."

Pre-CT advantages during COVID-19

Pre-CT offers additional advantages over Pre-TEE during the COVID-19 pandemic.
