Coronary CT angiography has been increasingly used in the diagnosis of coronary artery disease owing to rapid technological developments, which are reflected in the improved spatial and temporal resolution of the images. High diagnostic accuracy has been achieved with multislice CT scanners (64 slice and higher), and in selected patients coronary CT angiography is regarded as a reliable alterna...

We studied 8 patients with cerebral infarction in the deep territory of the middle cerebral artery (MCA). All patients had a definite cardiac source of emboli and no known factors for thrombosis. Mixed sensory and motor deficit was found in all but one patient and CT scan showed larger lesions than usually reported in lacunar infarcts. Contrast enhancement was seen in all cases in which CT scan...

BACKGROUND The diagnostic performance of cardiac computed tomography (CT) for detection of paravalvular leakage (PVL) after mitral valve replacement has not been investigated in a large population. We aimed to investigate the diagnostic accuracy of CT for diagnosis of mitral PVL using surgical findings as the standard reference and to compare the diagnostic performance of CT with those of trans...

Hyperaldosteronim is associated with left ventricular (LV) hypertrophy (LVH) and fibrosis. Cardiotrophin (CT)-1 is a cytokine that induces myocardial remodeling. We investigated whether CT-1 mediates aldosterone (Aldo)-induced myocardial remodeling in two experimental models. Wistar rats were treated with Aldo-salt (1 mg·kg(-1)·day(-1)) with or without spironolactone (200 mg·kg(-1)·day(-1)) for...

Background: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. In addition, the stethoscope is not applicable for continues monitoring, and it is u...

The diagnosis and prognostic assessment of patients with suspected or known cardiac disease has become increasingly dependent upon the use of noninvasive cardiac imaging technologies. Two of these are well established, echocardiography and nuclear cardiology, and two are relatively recent, cardiac CT and cardiac magnetic resonance (CMR). Cardiac CT provides high-resolution images of the coronar...

RATIONALE Cardiac metastasis is known as a rare complication of head and neck malignancy. PATIENT CONCERNS We present a 58-year-old woman patient with a history of tongue carcinoma who was admitted in emergency department for sudden chest pain. Imaging work-up by computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) diagnosed a cardiac metastasis complicated b...
