As a consequence of improved technology, there is growing clinical interest in the use of
multi-detector row computed tomography (MDCT) for non-invasive coronary angiography …

(signal void) due to the dephasing of moving protons. This approach can help show the
location of “jets” and optimize the location of velocity sampling. Although SSFP provides …

BACKGROUND: Measurement of left ventricular outflow tract (LVOT) area for estimation of
aortic valve area (AVA) using two-dimensional (2D) transthoracic echocardiography (TTE) …

Importance Aortic stenosis is the most common form of valvular heart disease. Progression
of aortic stenosis is very slow and highly variable. Decisions about when to perform valve …

OBJECTIVE: To determine the radiation doses and image quality of different dual-source
computed tomography coronary angiography (CTCA) protocols tailored to the heart rate …

OBJECTIVE. The purpose of this study was to prospectively evaluate the average heart rate
and heart rate variability required for diagnostic imaging of the coronary arteries with high …

OBJECTIVE. This study was conducted to assess the diagnostic value of cardiac CT for the
evaluation of patients with bicuspid aortic valve disease. MATERIALS AND METHODS. Fifty …

OBJECTIVE: Percutaneous aortic valve replacement is an emerging therapy for selected
patients with severe aortic stenosis. Preoperative imaging of the aortic root facilitates sizing …

Valvular disease is estimated to account for as many as 20% of cardiac surgical procedures
performed in the United States. It may be congenital in origin or secondary to another …

OBJECTIVE. The purpose of this study is to evaluate the diagnostic performance of CT,
compared with that of echocardiography and surgery, for differentiating between bicuspid …
