History of Right Heart Catheterization

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...

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...

"From right to left": The role of right heart catheterization in the diagnosis and management of left heart diseases.

Pulmonary hypertension (PH), second only to left heart diseases (LHD), is a frequent problem in clinical practice. At the same time, left heart diseases represent the most common cause of pulmonary hypertension, and the occurrence of PH in patients with chronic heart failure is usually associated with worse functional class, and prognosis. Right heart catheterization (RHC) is the "gold standard...
