Detailed explanation-1: -The current gold standard method to perform valve measurements and preprocedural TAVR planning is the multi-detector computed angiotomography (MDCT), with an appropriate TAVR protocol [15, 16]. MDCT measurements can be performed manually, using semi-automated software, or using automated software.
Detailed explanation-2: -The preoperative evaluation for TAVR includes transthoracic echocardiography (TTE) for the diagnosis of aortic stenosis. Cardiac computed tomography (CTA) has become the imaging modality of choice for annular sizing.
Detailed explanation-3: -In surgical series, a SAA is most frequently defined as an annulus that would not accommodate a prosthesis size >21 mm. An aortic annulus ≤23 mm, measured either preoperatively by echocardiography or intraoperatively by direct sizing, has also been proposed to define SAA.
