B-34 | Coarctation Angioplasty in Young Children: Does IMPACT Registry Data Accurately Reflect Clinical Outcomes?

BackgroundBalloon angioplasty for recoarctation of the aorta is routinely performed in young children. Angioplasty considered successful when systolic gradient reduced to <20 mmHg. The IMPACT Registry intended stratify institutions based on outcomes and make that data available public. defines acute procedural success solely a final <10 mmHg.MethodsBetween February 2012 December 2020, was 110 coarctation interventions. Electronic medical records were reviewed, primary endpoints one following: 1) analysis end date (June 2021), 2) patient death, or 3) most recent transcatheter surgical reintervention.Results64 (58.2%) interventions had post-procedure CA mmHg, while 96 (87.3%) gradients Comparison clinical outcome with previously published criteria demonstrated no significant relationship using (p = 0.70) 0.88). There difference between failure for: pre- post-treatment gradients; absolute percent change gradient; pre-treatment diameter. Clinical age did show 0.0093) better older patients.ConclusionsThe metric treatment does not predict actual at our institution. These findings underscore need identify other metrics following balloon treatment.DisclosuresM. H. Hoyer: Abbott: Physician Proctor; W.L. Gore Associates, Inc.: A. P. Desai Nothing disclose.
