results the degree of systolic compression was found to be correlated with the depth of the mb. however, there was no correlation between the length of the mb and the degree of systolic compression. conclusion the systolic compression of the mb was influenced by the depth of the tunneled segment, not by its length. background myocardial bridging (mb) is a congenital anomaly in which a segment o...

OBJECTIVE To study the predictive value of transluminal attenuation gradient (TAG) derived from diastolic phase of coronary computed tomography angiography (CCTA) for identifying systolic compression of myocardial bridge (MB). MATERIALS AND METHODS Consecutive patients diagnosed with MB based on CCTA findings and without obstructive coronary artery disease were retrospectively enrolled. In to...

BACKGROUND Myocardial bridging (MB) is a congenital anomaly in which a segment of a major epicardial coronary artery courses through the myocardium. This anomaly can lead to myocardial ischemia, arrhythmia, and even death. The effectiveness of coronary computed tomographic angiography (CCTA) in the detection of MB and its morphological features, and the accuracy of invasive coronary angiography...

OBJECTIVES The aim of this study was to retrospectively evaluate the morphologic and functional features of myocardial bridging (MB) and to investigate the impact of morphologic features on presence of atherosclerosis with multi-detector computed tomography (MDCT) coronary angiography. STUDY DESIGN The study population consisted of 191 consecutive patients. Besides coronary lesions, morpholog...

PURPOSE To prospectively assess the depiction rate and morphologic features of myocardial bridging (MB) of coronary arteries with 64-section computed tomographic (CT) coronary angiography in comparison to conventional coronary angiography. MATERIALS AND METHODS Patients were simultaneously enrolled in a prospective study comparing CT and conventional coronary angiography, for which ethics com...

Systolic arrays are a family of parallel computer architectures capable of using a very large number of processors simultaneously for important computations in applications such as scientific computing and signal processing. A discrete cosine transform (DCT) expresses a sequence of finitely many data points in terms of a sum of cosine functions at different frequencies. DCT is a Fourier-related...

A 68-year-old man was admitted to our hospital complaining of chest pain on exertion. Transthoracic echocardiography was normal. Coronary angiography showed insignificant stenosis in the left coronary artery. The right coronary artery (RCA) exhibited systolic compression in the proximal portion of the vessel (Picture 1A). The next day, the patient underwent single photon emission computed tomog...

BACKGROUND Aortic valve stenosis (AS) can cause angina despite unobstructed coronary arteries, which may be related to increased compression of the intramural microcirculation, especially at the subendocardium. We assessed coronary wave intensity and phasic flow velocity patterns to unravel changes in cardiac-coronary interaction because of transcatheter aortic valve implantation (TAVI). METH...
