How to Read a TAVR Planning CT

Transcatheter aortic valve replacements (TAVRs) are often placed in patients with symptomatic severe aortic stenosis for whom surgical aortic valve replacement would be particularly risky. Anatomic assessment of the patient on CT imaging helps determine the appropriate type and size of valve to deploy and evaluates the access route for its insertion. It can also help assess the risk of complications such as aortic annular injury and coronary occlusion, and predict fluoroscopic projection angles that will provide orthogonal views of aortic valve in the lab. 00:00 - Introduction 01:57 - CT Protocol 04:27 - Step 1: Non-Vascular Interpretation 04:45 - Step 2: Access Route for Procedure 09:26 - Step 3: Cardiac Interpretation 10:33 - Step 4: Aortic Valve Assessment 10:36 - Aortic Valve Anatomy 12:58 - Obtaining True Aortic Valve Plane on MPRs 16:44 - Aortic Annulus 18:35 - LVOT 20:18 - Sinuses of Valsalva 21:13 - Sinus Heights 22:37 - Coronary Artery Heights 23:30 - Sinotubular Junction 24:08 - Ascending Aorta 24:22 - Angle of Aortic Root 24:46 - Aortic Valve Cine
