THE PHYSICIAN who desires to carry out hemodynamic or angiocardiographic studies of the left side of the heart has a large number of technics froim which to choose.1 The ideal method for such investigations should fulfill a number of criteria. First of all, the method must be relatively safe. In order to gain wide acceptaniee it must be technically simple and individuals trained in the standard...
Background & Aim: Physiologic signs of anxiety usually change hemodynamic variables in patients undergoing heart catheterization. This study carried out to determine the effect of Orientation Program on hemodynamic variables in patient undergoing heart catheterization. Methods & Materials: In this experimental study, 60 patients undergoing heart catheterization were randomly assigned to eith...
neous method of right and left heart catheterization was used in 127 patients. In infants and children weighing more than 10 pounds, the percutaneous method was found to be an effective technic associated with a 3% incidence of diminished arterial pulses in the catheterized limb. All patients in this weight group, except one, had left heart catheterization by this technic. The method was deemed...
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...
conclusions based on the results of this study, we suggest the use of a novel “time from the beginning of isovolumetric contraction to the peak of the s wave” (ttp) parameter in the tdi of the base of the rv free wall to predict ph with acceptable accuracy in comparison with rhc. results in our study, the ttp showed a significant inverse relationship with the pap. based on our results, a ttp of...
BACKGROUND Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free di...
Methods Fifty patients undergoing clinically indicated right heart catheterization were prospectively recruited to a research CMR within 5 hours of catheterization. Majority of the heart failure cases were due to left heart failure. SSFP cine images were acquired to evaluate RV regional and global function. RV longitudinal and long axis radial strains were derived from the 4-chamber cine, and m...
especially in medical patients with respiratory failure. Because of these data limitations, we do not believe that undue reliance on formulas and guidelines alone will prevent nutritional complications. Our case report illustrated the problem ofweaning difficulties due to nutritionally associated hypercapnia in a patient population not commonly thought to be susceptible to this problem. We feel...
