Abstract

OBJECTIVE:

Neo-aortic insufficiency (neo-AI) has been noted following the Ross procedure. The purpose of this study was to evaluate the ability of intraoperative transesophageal echocardiography (TEE) to predict future neo-AI in pediatric patients undergoing the Ross from January 1995 to December 2003, who had an intraoperative TEE, and discharge and follow-up transthoracic (TTE) echocardiograms.

DESIGN:

Retrospective case series.

PATIENTS:

All patients who underwent the Ross procedure at Children's Hospital of Philadephia between January 1995 and December 2003, and had an intraoperative TEE, discharge, and follow-up (>6 months) transthoracic echocardiogram (TTE) (by July 1, 2004) were included.

OUTCOME MEASURES:

Grade of neo-AI was assessed on intraoperative TEE, discharge, and follow-up TTE echocardiogram reports.

RESULTS:

Follow-up was available in 99/115 (86%) survivors. Median age at Ross was 9.3 years (4 days-34 years). No patient had more than mild neo-AI on intraoperative TEE. At discharge, 2 patients (2%) had moderate neo-AI. At most recent follow-up (median 4.2 years, 8 months-9.3 years), 21 patients (21%) had moderate or greater neo-AI; 9 underwent neo-aortic reintervention. The presence of any neo-AI on intraoperative TEE had 100% sensitivity and negative predictive value for diagnosing moderate or greater neo-AI at discharge. Patients who had mild neo-AI on TEE were more likely to have moderate or greater neo-AI at most recent follow-up than those patients with no neo-AI on TEE (9% vs. 30%, P = 0.01).

CONCLUSION:

Intraoperative TEE is an excellent screening tool for the presence of significant neo-AI at the time of hospital discharge. Neo-AI progresses over time after Ross procedure and is more likely to progress in those patients with neo-AI on intraoperative TEE. However, predictive validity decreases over time as neo-AI progresses.
