BACKGROUND Transient arrhythmias can affect transient ischemic dilation (TID) ratios. This study was initiated to evaluate the frequency and effect of normal heart rate change on TID measures in routine clinical practice. METHODS Consecutive patients undergoing stress/rest sestamibi gated myocardial perfusion scintigraphy were studied (N = 407). Heart rate at the time of stress and rest imagi...
OBJECTIVES Transapical aortic valve implantation (TA-AVI) using the Edwards SAPIEN™ prosthesis has evolved into a routine procedure for selected high-risk elderly patients. The recently introduced SAPIEN™ delivery system (Ascendra II+™) with an added nose cone seems to facilitate direct valve implantation without prior balloon valvuloplasty (BAV). Here, we report our initial experience with thi...
Introduction: Development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. Blood brain barrier (BBB) opening is an important part of edema named as vasogenic brain edema. In this study, quantitative alterations of BBB permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. Methods: Two groups of male rats (ischemic and sh...
