Overview

Preoperative parameters may aid risk stratification in young AR patients; hypothesis-generating and should not yet alter intervention thresholds.

Key Points

  • To identify preoperative echocardiographic and cardiac magnetic resonance parameters linked to postoperative left ventricular recovery in young patients with aortic regurgitation.
  • Retrospective study of patients under 30 years with moderate-to-severe aortic regurgitation undergoing aortic valve surgery.
  • Compared preoperative imaging variables in patients with and without left ventricular recovery.
  • Used logistic regression analysis to find predictors of postoperative left ventricular recovery.
  • 91% of patients showed postoperative improvement in left ventricular dimensions.
  • 77% achieved complete left ventricular recovery.
  • Larger echocardiographic left ventricular end-systolic volume linked to reduced odds of recovery, while impaired global circumferential strain indicated failure to recover.

Structured PICO

Do preoperative echocardiographic and CMR parameters predict postoperative LV recovery in pediatric and young adult patients undergoing aortic valve surgery for moderate-to-severe aortic regurgitation?

P
Population
22 patients younger than 30 years with moderate-to-severe aortic regurgitation who underwent aortic valve surgery, evaluated for left ventricular recovery at 6-12 months.
E
Exposure
Preoperative echocardiogram and cardiac magnetic resonance (CMR) assessment prior to aortic valve surgery
O
Outcome
Postoperative LV recovery (defined as normalization of LV volumes and systolic function within 6-12 months following surgery)surrogate

In pediatric and young adult patients with chronic aortic regurgitation, preoperative echocardiographic LVESV and CMR-derived global circumferential strain are better predictors of postoperative LV recovery than adult-derived volumetric thresholds.

Limitations

  • Requires validation in larger prospective studies
  • Small sample size
  • Retrospective design

Cite This Study

Flerlage et al. (2026) conducted an observational in chronic aortic regurgitation (n=22). Preoperative echocardiographic LVESV and CMR-derived GCS was evaluated on Postoperative LV recovery (normalization of LV volumes and systolic function within 6-12 months following surgery). Larger preoperative echocardiographic LV end-systolic volume and impaired CMR-derived global circumferential strain were associated with reduced odds of postoperative LV recovery.
