A’ has been correlated with LA function.

Intravascular catheters can measure the velocity of blood flow within a coronary artery but color flow, PW and CW are not possible.

In patients with truly sever aortic stenosis the infusion of dobutamine increases the peak velocity and TVI of both the LVOT and aortic valve

Aortic Cannulation –  The red rubber catheters are cut into how many inches

Intravascular ultrasound provides information that helps determine which angioplasty procedure would be best to treat blockage.

For patients who have mainly exertional symptoms and in whom resting hemodynamics do not clearly indicate severe mitral stenosis, it is helpful to perform the Doppler hemodynamics assessment during bicycle exercise or immediately after treadmill exercise.

Draw a typical pump characteristic curve and label the axes with units (British). Then draw a typical system head curve on the same graph. Clearly label both curves and the match point.  

 Serial echocardiographic studies are performed post valvuloplasty to:

Venous Cannulation – Step 4 – A 3 stage venous cannula that drains blood from the right atrium, inferior vena cava, and coronary sinus is inserted, and the red rubber catheter is cinched loosely over the purse-string suture securing the cannula

A 0.5 kg block of aluminum (specific heat capacity = 900 J/kg·°C) is heated from 20°C to 80°C using a 2.0 kg container of water (specific heat capacity = 4186 J/kg·°C) initially at 25°C. Assume no heat is lost to the environment. A 1000 J heat source is applied to the aluminum block. Calculate the temperature increase it causes.
