Transcatheter aortic valve replacement (TAVR) is becoming the gold standard when repairing aortic stenosis compared to surgical aortic valve replacement (SAVR). Transcatheter aortic valve replacement is minimally invasive. Aortic stenosis is the most common valvular disease in the United States, commonly seen in the elderly population. In this project, multi-imaging modalities are discussed when preparing a patient for TAVR such as computed tomography, left heart catheterization, and transthoracic echocardiography. Each imaging modality has its own specialty in the preprocedural planning of a valve replacement. Computed tomography uses 3D reconstruction to determine the type of valve and size needed for the patient. Transthoracic echocardiography evaluates the severity of aortic stenosis along with the morphologic classification. Left heart catheterizations can determine the severity of aortic stenosis by measuring pressure gradients between the aorta and left ventricle. Patients who undergo transcatheter aortic valve replacement experience a better quality of life, and less major complications when compared to surgical aortic valve replacement (SAVR).
