The clinical use of a flow-directed balloon-tipped catheter to measure intracardiac filling pressures was first published by Swan et al1 in 1970. Careful hemodynamic studies using pulmonary artery (PA) catheters provided the basis for our understanding of the pathophysiologic mechanisms of heart failure, which were previously poorly understood. The detailed hemodynamic data obtained with PA catheterization provide important diagnostic information, and PA catheterization remains the procedure of choice for the diagnosis of pulmonary arterial hypertension, shock of unclear etiology, and quantification of intracardiac shunts.2
