Renal artery duplex ultrasonography (RA-DUS) is commonly used for the evaluation and follow-up of renal artery atherosclerotic disease. In a complete study, renal artery flow is evaluated from the vessel origin to the intraparenchymal branches. The quality of RA-DUS is in part technologist-dependent, but many factors may affect the ability ...

A 32-year-old woman was admitted to our institution for further evaluation of aortic stenosis. Diagnosis of severe aortic stenosis was made by transthoracic echocardiography. Transesophageal echocardiography, live three-dimensional echocardiography and cardiovascular MRI allowed precise evaluation of valve morphology. Interestingly, valve morphology was unicuspid unicommissural with a posterior funnel-shaped valve opening. ...

Radial artery occlusion (RAO) is an infrequent but important consequence of transradial access. It prevents subsequent use of the same radial artery for coronary angiography and intervention. We describe a new "proximal entry" technique in 3 cases of RAO, which allowed successful completion of the procedures. This technique should add ...

BACKGROUND: Endothelial function is best measured with the noninvasive brachial artery flow-mediated dilatation (FMD) method. Peripheral arterial diseases and systemic cardiovascular diseases have FMD-lowering effect. The effects of lower extremity ischemia are associated with muscle inflammation and claudication, which may further lead to arterial stress. Our aim in this study ...

Whether the relief of chronic right atrial (RA) volume load by device closure of an atrial septal defect (ASD) normalizes RA size is unknown. The present study evaluated the prevalence and determinants of incomplete RA reverse remodeling (RAR) after ASD closure in adults. Transthoracic echocardiography was performed in 44 consecutive ...

OBJECTIVES: Arteriovenous fistulae (AVFs) play a key role for people who rely on chronic haemodialysis. Stenosis in the venous outflow of the AVF will cause an alternative route of the subcutaneous blood flow via the deeper venous pathways by means of side branches and the perforating veins (PVs). The purpose ...

INTRODUCTION: Combined aneurysms of aortic and iliac arteries are rare with a prevalence of less than 0.1%. However, these combined aneurysms are associated with a high incidence of thrombosis, distal embolism or rupture. Endovascular repair is a therapeutic option. The procedure often includes embolisation of the internal iliac artery, which ...
