Coronary artery catheterization in the intact dog.
STUDIES of the coronary circulation by injections of drugs, embolizing particles or radio-opaque materials into the coronary arteries until recently have necessitated a choice between opening the chest for direct injections, and indirect injection through a catheter into the vicinity of the coronary ostia without opening the chest. The advantages of both approaches could be combined, and their ...
متن کاملCoronary physiology revisited : practical insights from the cardiac catheterization laboratory.
Various coronary physiological measurements can be made in the cardiac catheterization laboratory using sensor-tipped guidewires; they include the measurement of poststenotic absolute coronary flow reserve, the relative coronary flow reserve, and the pressure-derived fractional flow reserve of the myocardium. Ambiguity regarding abnormal microcirculation has been reduced or eliminated with meas...
متن کاملCardiac Catheterization and Coronary Angiography in Patients with Cardiomyopathy
Cardiomyopathies are a group of heart diseases that influence muscles directly and are not related to congenital, valvular, and pericardial diseases (Salehifar et al., 2008). Cardiomyopathies are usually classified on the basis of structural or functional causes. Thus, dilated cardiomyopathy is characterized by an enlarged ventricular chamber size and reduced cardiac contractility, hypertrophic...
متن کاملCurrent concepts of integrated coronary physiology in the catheterization laboratory.
Over the last 15 years, the use of invasive coronary physiology in the catheterization laboratory has demonstrated favorable outcomes for decision making in patients with intermediate single-vessel stenoses, complex bifurcation and ostial branch stenoses, multivessel coronary artery disease, and left main stenoses. A recent large multicenter study (FAME [FFR versus Angiography for Multivessel E...
متن کاملReal-time magnetic resonance imaging-guided coronary catheterization in swine.
BACKGROUND We tested the hypothesis that real-time magnetic resonance imaging (MRI) can guide coronary artery catheterization in swine via a percutaneous femoral artery approach. METHODS AND RESULTS In 12 pigs, we accessed femoral arteries percutaneously. We used 6- or 7-French coronary Judkins catheters filled with dilute 4% gadolinium (Gd) contrast agent and coaxially inserted 0.030-inch di...
