Intraoperative assessment of pulmonary artery pressure using transesophageal echocardiography in patients undergoing cardiac surgery.

Intraoperative assessment of pulmonary artery pressure using transesophageal echocardiography in patients undergoing cardiac surgery. Proc (Bayl Univ Med Cent). 2018 Oct;31(4):404-406 Authors: Zaki JF, Aijazi M, Wong MA, Choi W, Moise OL, Tran SF, Pawelek TR, Zhou SF, Sheinbaum R, Fonseca AC, Markham T Abstract We performed a retrospective chart review to investigate a potential relation between pulmonary artery (PA) diameter as measured by intraoperative transesophageal echocardiography and PA pressures measured by PA catheter with the aim of determining whether main PA diameter can aid clinicians in the diagnosis of PA hypertension. A total of 82 adult patients undergoing cardiac surgery were included in our study. Main PA diameter showed a moderate correlation with systolic and diastolic pressures, r = 0.576 (95% confidence interval [CI], 0.407-0.703), P < 0.001, and r = 0.504 (95% CI, 0.319-0.648), P < 0.001, respectively. The authors believe that although a moderate correlation exists between main PA diameter and PA pressure, confounding hemodynamic variables prevent main PA diameter from being an accurate and reliable means of diagnosing PA hypertension.
