Article Title: Catheter-based examination for pulmonary microcirculatory function in patients with pulmonary hypertension
doi: 10.1371/journal.pone.0312609
Figure Lengend Snippet: (A) The pulmonary arteries in the lower lobe of the right lung are shown using contrast medium. The suitable pulmonary artery to facilitate the placement of a temperature- and pressure-sensor guidewire was selected with an angiogram. The white arrows indicate a guiding catheter used to inject the contrast medium and deliver the guidewire. The catheter was delivered from the inferior vena cava to the right central pulmonary artery. (B) The white arrow indicates the guidewire placed distally to the pulmonary artery to measure blood pressure and mean transit times in the artery. (C) A final angiogram following the above measurements indicated no occurrence of vascular complications in the artery.
Article Snippet: To evaluate the pulmonary microcirculatory function, the mean proximal pulmonary artery pressure (Pp), mean distal pulmonary artery pressure (Pd), and mean transit time (Tmn) were measured using a temperature- and pressure-sensor guidewire (PressureWireTM X Guidewire Wireless or Cabled, Abbott, Santa Clara, CA, USA).
