Coarctation of aorta; Aortic regurgitation; Left ventricular remodeling; Aortic valve replacement
This study compared left ventricular remodeling and clinical outcomes in adults with repaired coarctation of aorta (COA) and aortic regurgitation (AR) to those without COA. The results showed that patients with COA had higher left ventricular mass index and E/e ' before aortic valve replacement, and less regression of left ventricular mass index and E/e ' after the surgery.
Background: Aortic regurgitation (AR) can develop in adults with repaired coarctation of aorta (COA), but there are limited data about left ventricular (LV) remodeling and clinical outcomes in this population. The purpose of the study was to compare LV remodeling (LV mass index [LVMI], LV ejection fraction [LVEF], and septal E/e ') and onset of symptoms before aortic valve replacement, and LV reverse remodeling (%-change in LVMI, LVEF and E/e ') after aortic valve replacement in patients with versus without repaired COA presenting with AR.Methods: Asymptomatic adults with repaired COA presenting with moderate/severe AR (AR-COA group) were matched 1:2 to asymptomatic adults without COA and similar severity of AR (control group).Results: Although both groups (AR-COA n = 52, and control n = 104) had similar age, sex, body mass index, aortic valve gradient, and AR severity, the AR-COA group had higher LVMI (124 +/- 28 versus 102 +/- 25 g/m2, p < 0.001) and E/e ' (12.3 +/- 2.3 versus 9.5 +/- 2.1, p = 0.02) but similar LVEF (63 +/- 9% versus 67 +/- 10%, p = 0.4). COA diagnosis (adjusted HR 1.95, 95%CI 1.49-2.37, p < 0.001), older age, E/e ', and LV hypertrophy were associated with onset of symptoms. Of 89 patients (AR-COA n = 41, and control n = 48) with echocardiographic data at 1-year post- aortic valve replacement, the AR-COA group had less regression of LVMI (-8% [95%CI -5 to -11] versus -17% [95%CI -15 to - 21], p < 0.001) and E/e ' (-5% [95% CI -3 to -7] versus -16% [95% CI -13 to -19], p < 0.001).Conclusions: Patients with COA and AR had a more aggressive clinical course, and perhaps may require a different threshold for surgical intervention.
