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...
Right heart catheterization remains necessary for the diagnosis of pulmonary hypertension and, therefore, prognostic evaluation patients with chronic failure. The non-invaSive Assessment Pulmonary vasculoPathy in Heart failure (SAPPHIRE) study was designed to assess feasibility and relevance a non-invasive artery vasculature hypertension. Patients will undergo right catheterization, cardiac res...
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...
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...
