CT may provide additional insight in the setting of suspected mechanical prosthetic valve dysfunction [24] and can also provide precise concomitant anatomic delineation of the entire aorta. CT is increasingly utilized as part of a comprehensive preprocedural preparation for VHD interventions. CT imaging of cardiac and vascular structures plays a critical role in the planning of transcatheter aortic valve Dyspnea-Suspected Cardiac Origin replacement [25], and up to 30.9% and 32.6% of those with suspect clinical and echocardiographic findings posttranscatheter aortic valve replacement or surgical aortic valve repair, respectively [26]. CT imaging is increasingly utilized in planning transcatheter interventions for valvular and structural heart disease beyond the aortic valve [27-29] as well as planning, risk stratification, and follow-up of surgical interventions for VHD [26]. Epicardial fat as assessed on CT has shown correlation with mitral annular and aortic leaflet calcification [30], although this is not routinely employed in clinical practice. CTA Coronary Arteries There is no relevant literature to support the use of CTA coronary arteries for the evaluation of dyspnea due to suspected VHD, ischemia excluded. Coronary ostia heights relative to aortic annulus are assessed on CTA as part of transcatheter aortic valve planning [25]. FDG-PET/CT Heart There is no relevant literature to support the use of fluorine-18-2-fluoro-2-deoxy-D-glucose (FDG)-PET/CT heart for the evaluation of dyspnea due to suspected VHD, ischemia excluded. MRI Heart Function and Morphology MRI plays a complementary role to echocardiography in the assessment of suspected VHD.
