Noninvasive evaluation of the aortic root with multislice computed tomography implications for transcatheter aortic valve replacement.
OBJECTIVES In the present study, the anatomy of the aortic root was assessed noninvasively with multislice computed tomography (MSCT). BACKGROUND Transcatheter aortic valve replacement has been proposed as an alternative to surgery in high-risk patients with severe aortic stenosis. For this procedure, detailed knowledge of aortic annulus diameters and the relation between the annulus and the ...
متن کاملNoninvasive coronary angiography with multislice computed tomography.
CONTEXT Multislice computed tomography (MSCT) has recently evolved as a modality for noninvasive coronary imaging. OBJECTIVE To assess the accuracy and robustness of MSCT vs the criterion standard of invasive coronary angiography for detection of obstructive coronary artery disease. DESIGN, SETTING, AND PATIENTS Prospective, single-center study conducted in a referral center setting in Germ...
متن کاملNoninvasive evaluation of the coronary arteries with multislice computed tomography in hypertensive patients.
Because patients with hypertension are at increased risk for coronary artery disease, early and noninvasive identification of the disease in patients with hypertension is important. Recently, multislice computed tomography (MSCT) has been demonstrated to allow both noninvasive coronary angiography and assessment of left ventricular function. The purpose of the present study therefore was to dem...
متن کاملNoninvasive Evaluation With Multislice Computed Tomography in Suspected Acute Coronary Syndrome
Methods In 40 patients (age 57 11 years, 26 men) presenting with suspected ACS, MSCT coronary angiography in combination with coronary calcium scoring was performed before conventional coronary angiography. MSCT angiograms were evaluated for the presence or absence of coronary atherosclerotic plaque and the presence or absence of obstructive ( 50% luminal narrowing) CAD. In addition, plaque typ...
متن کاملNoninvasive coronary artery imaging by multislice spiral computed tomography.
Although the excellent spatial resolution of multislice spiral computed tomography (MSCT) enables the coronary arteries to be visualized, its limited temporal resolution results in poor image reproducibility because of cardiac motion artifact (CMA) and hence limits its widespread clinical use. A novel retrospectively ECG-gated reconstruction method has been developed to minimize CMA. In 88 cons...
