To evaluate the feasibility and diagnostic accuracy of adenosine-stress dual-energy computed tomography (DECT) for detecting haemodynamically significant stenosis causing reversible myocardial perfusion defect (PD) compared with stress perfusion magnetic resonance imaging (SP-MRI) and conventional coronary angiography (CCA). Fifty patients with known(More)
OBJECTIVE The purpose of our study was to prospectively evaluate the incremental diagnostic value of combined dual-source coronary CT angiography (CTA) and CT myocardial perfusion imaging (MPI) for the detection of significant coronary stenoses. SUBJECTS AND METHODS Forty-five patients with known coronary artery disease detected by dual-source coronary(More)
To compare the diagnostic accuracies of coronary computed tomography angiography (CCTA), cardiovascular magnetic resonance (CMR), and transthoracic echocardiography (TTE) in aortic valve (AV) morphological assessments with operative findings. We retrospectively enrolled 262 patients who underwent CCTA, CMR, and TTE before AV surgery. Two independent blinded(More)
BACKGROUND Aortic valve reconstruction surgery (AVRS), consisting of aortic leaflet reconstruction with tailored pericardial patches and fixation of the sinotubular junction with properly sized fabric rings, is performed for the treatment of aortic valve diseases. The early and midterm outcomes of AVRS were analyzed. METHODS Between December 2007 and(More)
We assessed the diagnostic performance of stress- and rest-dual-energy computed tomography (DECT) and their incremental value when used with coronary CT angiography (CCTA) compared with combined invasive coronary angiography (ICA)/cardiovascular magnetic resonance (CMR) for detecting hemodynamically significant stenosis causing a myocardial perfusion(More)
OBJECTIVE The present study was aimed to assess the results of newly developed aortic valve repair technique. METHODS Between 1997 and 2004, 69 aortic valvuloplasties were performed with a new technique addressing the three main components of the aortic root; leaflets (L), sinotubular junction (STJ), and aortic annulus (A). For leaflet correction,(More)
BACKGROUND Quadricuspid aortic valve (QAV) is a rare congenital anomaly. We investigate the mid-term results of aortic valve reconstruction by tricuspidization in patients with QAV. METHODS We analyzed the outcome of eight consecutive patients who underwent aortic valve reconstruction surgery (AVRS) with pericardial leaflets with symptomatic quadricuspid(More)
OBJECTIVE The purpose of this study was to assess the diagnostic performance of stress perfusion dual-energy CT (DECT) and its incremental value when used with coronary CT angiography (CTA) for identifying hemodynamically significant coronary artery disease. SUBJECTS AND METHODS One hundred patients with suspected or known coronary artery disease without(More)
We sought to determine the cut-off point of the average heart rate (HR) and HR differences in obtaining diagnostic image quality using prospective electrocardiographically-triggered (PT) coronary computed tomographic angiography (CCTA) and to compare image quality and radiation dose for CCTA obtained with PT CCTA and retrospective(More)
OBJECTIVE Cardiac MDCT and cardiovascular MRI have become widely used for the evaluation of cardiovascular disease, including aortic valve disease. The purpose of this article is to present the cardiac MDCT and cardiovascular MRI findings of bicuspid aortic valve, its various complications, and other congenital cardiovascular malformations.
