Pulmonary Hypertension
I was a recently minted fellow at Duke University Medical Center in early 1998 when my mentor, Dr Bashore, asked me to come up with a research project utilizing a device he had just purchased for the catheterization laboratory. The INOvent Delivery System (Ohmeda Medical, Laurel, MD, USA) facilitated the controlled delivery of nitric oxide blended with oxygen through a ventilator circuit.1 I immediately began working on my institutional review board submission with a goal to study patients with what was then known as “primary pulmonary hypertension” and compare them with patients with “secondary pulmonary hypertension.”2 Even then we were careful to exclude patients with elevated pulmonary capillary wedge pressure from our study, as we understood the difference in pathophysiology between precapillary and postcapillary forms of pulmonary hypertension (PH) and that the therapeutic approaches to these conditions greatly differed.
