Cardiac catheterization allows the invasive acquisition of haemodynamic data using direct and indirect pressure measurements, oxygen saturations and provides anatomical information using contrast angiography. Right heart catheterization used to be a routine part of an invasive cardiac study. The increased accessibility and accuracy of non-invasive imaging (in particular echocardiography and Doppler techniques) has reduced the need to perform right heart catheterization. Always review non-invasive imaging prior to performing an invasive study and confirm that the test remains indicated....
