Right heart catheterisation is a minimally invasive procedure to measure to pressures in the heart and arteries of the lungs. This test is done in patients in which the need to determine accurately a condition called pulmonary hypertension as well as other congenital heart conditions.
This procedure involves insertion of a very thin flexible tube called a catheter through the vein of the body and it is manoeuvred carefully into the heart chambers. The tip of this catheter is able to measure the pressure within the chambers of the heart, ascertain how much oxygen is in the blood and the amount of blood the heart is able to pump.
Sometimes a vasodilator test may also be performed during the right heart catheterisation to see the blood pressure response in your pulmonary arteries when a fast-acting blood pressure–reducing medication is given.
All these test results will help us make an accurate diagnosis on specific conditions and determine the most appropriate treatment.
