Figure 4. Baseline hemodynamic data during right-heart catheterization. Aorta (Ao), right ventricle (RV), pulmonary artery (PA), and right atrium (RA) pressure tracings. Note the clear fall in systemic pressure when crossing the pulmonary valve and subsequent pressure recovery after catheter pullback. This can be explained by mechanical obstruction of a narrowed pulmonary orifice and relief of this obstruction after catheter withdrawal. This is similar to Carabello’s sign in critical aortic stenosis.
