The Association of the Pulmonary Artery Pulsatility Index and Right Ventricular Function after Cardiac Surgery.

ABSTRACT:

Background

The pulmonary artery pulsatility index (PAPi) has been shown to correlate with right ventricular (RV) failure in patients with cardiac disease. However, the association of PAPi with right ventricular function following cardiac surgery is not yet established.

Methods

PAPi and other hemodynamic variables were obtained postoperatively for 959 adult patients undergoing cardiac surgery. The association of post-bypass right ventricular function and other clinical factors to PAPi was evaluated using linear regression. A propensity-score matched cohort for PAPi ≥ 2.00 was used to assess the association of PAPi with postoperative outcomes.

Results

156 patients (16.3%) had post-bypass right ventricular dysfunction defined by visualization on transesophageal echocardi
