AIMS Left heart catheterization carries a risk for cerebral complications. The aims of this prospective study were to determine the frequency and composition of catheterization-related cerebral microemboli and to detect cerebral morphological changes and acute cognitive impairment due to catheterization. METHODS AND RESULTS Forty-seven unselected patients undergoing elective left heart cathet...

background: primary percutaneous coronary intervention (primary pci) is the method of choice in establishing reperfusion in acute myocardial infarction (ami) patients. the aim of this study was to determine the success rate of primary pci in a university medical center in iran with a view to promoting it as a first-line therapy in patients with ami, especially in centers with established cathet...

conclusions the us-guided method for cvc placement was superior to the traditional landmark method in terms of access time, number of attempts, success rate, and fewer complications. objectives this study aimed to compare the traditional landmark method vs. us-guided method of cvc placement in terms of complications and success rate. patients and methods in this randomized controlled trial, pat...

conclusions despite close concordance between ultrasonography and chest radiography, ceus is not a suitable alternative for standard chest radiography in detecting cvc location; however, considering its high sensitivity and acceptable specificity in our study, its usefulness as a triage method for detecting cvc location on a real-time basis in the operating room cannot be ignored. results chest...

We present an evaluation of a novel technique for continuous (i.e., automatic) monitoring of relative cardiac output (CO) changes by long time interval analysis of a peripheral arterial blood pressure (ABP) waveform in humans. We specifically tested the mathematical analysis technique based on existing invasive and noninvasive hemodynamic data sets. With the former data set, we compared the app...

At cardiac catheterization, the effect of isoproterenol on coronary blood flow was compared in six patients with normal coronary arteries and normal left ventricular function, and eight patients with angiographically defined coronary lesions. Coronary blood flow was measured by selective coronary artery injection of xenon-133 and external monitoring of disappearance curves with a dual probe, di...
