Modern Right Heart Catheterization: Beyond Simple Hemodynamics

Role of right heart catheterization.

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...

Evaluation of the hemodynamics and right ventricular function in pulmonary hypertension by echocardiography compared with right-sided heart catheterization

The present study aimed to evaluate hemodynamics and right ventricular function in patients with pulmonary hypertension (PH) using transthoracic echocardiography and to compare these results with measurements obtained using right-sided heart catheterization (RHC). A total of 75 patients with PH were examined using echocardiography and RHC. Patients were divided into the following two groups acc...

Does right heart catheterization prevent perioperative complications?

An efficient, free-breathing protocol for MR right heart catheterization

Methods The baseline MR examination begins with cardiac localizers. At this stage it is important to verify isocenter because if the patient is too deep in the bore then femoral vascular access sheaths are inaccessible to the operator. Through-plane phase contrast (PC) scans in the ascending aorta and main pulmonary artery follow for quantification of Qp and Qs. To avoid the need to repeat long...

MR guided right heart catheterization - the NIH experience

Background Realtime MR enables radiation free guidance for right heart catheterization (RHC). In addition to catheter navigation for sampling of invasive pressures and blood oxygen saturations, MR permits concomitant assessment of cardiac chamber volumes and cardiac output with phase contrast flow measurements. By performing repeat measurements under different physiological provocations (e.g. s...
