A fluid-filled catheter capable of making high-fidelity systolic, diastolic, and mean pressure measurements and capable of allowing angiographic dye injection is used. Left-heart catheterization can be performed antegrade via the right atrium in patients in whom the atrial septum can be crossed via ...
What can the presence of red blood cells in the urine mean? Red blood cells can enter the urine from the vagina in menstruation or from the trauma of bladder catheterization. A high count of red blood cells in the urine can indicate infection, trauma, tumors, or kidney stones. If red bl...

Estimation of left-sided vascular pressures via catheterization of the right heart requires a static uninterrupted column of blood to be present from the tip of the PA catheter (PAC) to the aortic valve. At the end of diastole, there is no net flow in this common chamber, and if the ...
A patient with tetralogy of Fallot developed a continuous flow-like murmur after radical operation. At right-heart catheterization with intracardiac phonocardio-graphy, the continuous murmur was recorded in the entire inflow tract of the right ventricle and was erroneously interpreted as being due to ...
Careful collection of routine simultaneous left and right heart hemodynamics will document the individual valvular lesions. Combined echocardiography and angiographic data will further support the interpretation of the hemodynamic waveforms. Clinical decisions for valve repair or replacement will be based on ...
