Cardiovascular imaging trends in congenital heart disease: a single center experience.
Cardiac magnetic resonance imaging (MRI) and CT are available in the recent era at many pediatric cardiac centers. ⋯ Cardiac CT is used increasingly in the recent era for evaluation of CHD. The increased use of both cardiac CT and cardiac MRI are temporally associated with a decrease in diagnostic cardiac catheterization.

Diagnostic accuracy of CT angiography in infants with tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries.
CT angiography (CTA) is increasingly used for the evaluation of congenital heart disease. ⋯ CTA is accurate in the preoperative evaluation of infants with ToF-PA and MAPCAs and is associated with a substantially lower radiation dose than catheterization. Preoperative diagnostic catheterization, therefore, may only be necessary in select patients with small MAPCAs in whom the precise assessment of central pulmonary arteries is required for surgical planning.

Image quality of ultra-low-dose dual-source CT angiography using high-pitch spiral acquisition and iterative reconstruction in young children with congenital heart disease.
Obtaining diagnostic CT image quality with ultra-low radiation dose in young children with congenital heart disease remains challenging. ⋯ A combination of prospectively ECG-triggered high-pitch spiral acquisition, low tube current, and iterative reconstruction may offer diagnostic image quality in pediatric cardiovascular CT angiography with effective radiation dose < 0.1 mSv.

Multicenter StudyMultidetector CT predictors of prosthesis-patient mismatch in transcatheter aortic valve replacement.
Prosthesis-patient mismatch (PPM) is a predictor of mortality after aortic valve replacement (AVR). ⋯ PPM is frequent after TAVR. Appropriate annular oversizing does not reduce the rate or severity of PPM. Patient annulus size mismatch, identified by indexed MDCT annular area, is a significant predictor of PPM.

Comparative StudyRadiation dose in 320-slice multidetector cardiac CT: a single center experience of evolving dose minimization.
Minimization of radiation exposure remains an important subject that occurs in parallel with advances in scanner technology. ⋯ While maintaining diagnostic quality in 320-multidetector row cardiac CT, the radiation dose has decreased substantially because of a combination of dose-reduction protocols and technical improvements. Continued minimization of radiation dose will increase the potential for cardiac CT to expand as a cardiac imaging modality.
