Answer

Multimodality imaging is essential for preoperative planning and postoperative detection of potential complications. [20] Two-dimensional and Doppler echocardiography is the imaging modality of choice to diagnose and determine the severity of aortic stenosis. [5] In general, cardiac catheterization is not necessary to determine the severity of aortic stenosis. However, in instances in which clinical findings are not consistent with echocardiogram results, cardiac catheterization is recommended for further hemodynamic assessment.
