Does everyone with pulmonary hypertension need a catheterization to measure pressures?

In brief: No
Only those with poorly controlled pulmonary hypertension with recurrent right sided heart failure should undergo a catheterization.

All current accepted guidelines require a right heart cath to diagnose pulmonary arterial hypertension largely because almost all cases of increased pulmonary artery pressure detected by echocardiogram are caused by LV diastolic or systolic heart failure and not by PAH thus echocardiography is not sufficient to make a diagnosis leading to treatment of PAH.

In brief: Yes.
It's the only way to make the diagnosis.

In brief: Heart cath
Pulmonary Arterial Hypertension cannot be diagnosed without a right sided heart catheterization.
It's not all about pressure but is about flow produced by the heart, vascular resistance, as well as pressures in the heart chambers and vena cava.

A catheterization will best determine what the exact pressure is (you can diagnosed pulmonary hypertension clinically though, i.
e.: physical exam, ecg, cxr and echocardiography). Yet the most important info you get from a cath is whether the pressure responds to various medications available that can then be used a treatment for the elevated pulmonary pressures.

Almost all cases of increased pulmonary pressures detected by echocardiogram are shown at heart cath to be secondary to increased left ventricular filling pressures from either systolic or diastolic left heart failure. For this reason a right heart cath is absolutely necessary to properly diagnose and treat pulmonary arterial hypertension and this is why all the guidelines recommend it.
