Background
:
Patent ductus arteriosus (PDA) stenting allows neonates with critical congenital heart disease to maintain a stable post-natal circulation. Advanced CT imaging can aid in pre-procedural planning. We aim to review outcome variables between patients who did and did not undergo advanced CT imaging prior to PDA stenting.
Methods
:
Retrospective chart review of PDA stenting outcomes at our institution from 2014 to 2019. We specifically compared the number of access sites, procedural time, fluoroscopy time, and contrast needed between the cohorts.
Results
:
A total of 71 patients underwent successful PDA stenting with 28 (39%) obtaining pre-procedural advanced CT imaging. A comparison of the two groups is outlined in
Table 1. A case example of the process is summarized in
Figure 1.
Conclusions
:
Pre-procedural advanced CT imaging aids interventional planning for neonatal PDA stenting which results in a statistically significant reduction in number of access sites and contrast exposure. A trend toward reduction in procedural and fluoroscopic time is noted.
