  2. Cardiac catheterization - Wikipedia

    en.wikipedia.org/wiki/Cardiac_catheterization

    Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart.This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks").

  3. Pulmonary artery catheter - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_artery_catheter

    Non-invasive echocardiography and pulse-wave cardiac output monitoring are concordant with (and much safer) if not better than invasive methods defining right and left heart performance. The emergence of MRSA and similar hospital based catheter infections now clearly limits the utility of this type of invasive cardiac ICU intervention.

  4. Pulse pressure - Wikipedia

    en.wikipedia.org/wiki/Pulse_pressure

    It is measured by right heart catheterization or may be estimated by transthoracic echocardiography. Normal pulmonary artery pressure is 8 mmHg–20 mmHg at rest. [7] e.g. normal 15mmHg - 8mmHg = 7mmHg high 25mmHg - 10mmHg = 15mmHg

  5. Instantaneous wave-free ratio - Wikipedia

    en.wikipedia.org/wiki/Instantaneous_wave-free_ratio

    When stenoses are flow limiting, Pd and Pa pressures over the wave-free period diverge; a normal ratio is 1.0 and iFR values of below 0.90 suggest flow limitation. iFR can be calculated using dedicated consoles available for medical use and typically uses an average over 5 heart beats but can be performed using a single heart beat. iFR is ...

  6. Central venous pressure - Wikipedia

    en.wikipedia.org/wiki/Central_venous_pressure

    Normal CVP in patients can be measured from two points of reference: [citation needed] Sternum: 0–14 cm H 2 O; Midaxillary line: 8–15 cm H 2 O; CVP can be measured by connecting the patient's central venous catheter to a special infusion set which is connected to a small diameter water column. If the water column is calibrated properly the ...

  7. Aortic valve area calculation - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_area_calculation

    Example: An individual undergoes left and right heart cardiac catheterization as part of the evaluation of aortic stenosis. The following hemodynamic parameters were measured. With a heart rate of 80 beats/minute and a systolic ejection period of 0.33 seconds, the cardiac output was 5 liters/minute.

  8. Fractional flow reserve - Wikipedia

    en.wikipedia.org/wiki/Fractional_flow_reserve

    Fractional flow reserve (FFR) is a diagnostic technique used in coronary catheterization.FFR measures pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia).

  9. Coronary catheterization - Wikipedia

    en.wikipedia.org/wiki/Coronary_catheterization

    A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures.
