Key result
Thoracic curve in adolescent idiopathic scoliosis was associated with a 53.73% prevalence of valvular regurgitation compared to 43.75% in nonthoracic curves, with significantly higher tricuspid involvement.
Why the study?
Is thoracic curve scoliosis associated with a higher prevalence of valvular regurgitation compared to nonthoracic curve scoliosis in adolescents?
Observational (n=83)
Is thoracic curve scoliosis associated with a higher prevalence of valvular regurgitation compared to nonthoracic curve scoliosis in adolescents?
Absolute Event Rate: 53.73% vs 43.75%
Adolescent idiopathic scoliosis patients with thoracic curves have a significantly higher frequency of tricuspid valve regurgitation compared to those with nonthoracic curves.
May prompt targeted echocardiography in thoracic AIS; leaves open causal links and long-term cardiac impact.
Sixty-seven adolescent scoliosis patients with thoracic curve (Lenke type 1, 3, and 6) and 16 nonthoracic curve patients (Lenke type 5) were evaluated with color Doppler echocardiography to identify and compare the prevalence and frequency of valvular regurgitation. Regurgitation of one or more valves was detected in 36 thoracic curve patients (53.73%) and seven nonthoracic curve patients (43.75%). Regurgitation with tricuspid valve involvement was statistically significant in patients with thoracic curve (P=0.0216). Frequency of tricuspid valve involvement was statistically significant (28.57 vs. 83.33%, P=0.0076) in patients with thoracic curve. Those without cardiac disease had a higher incidence of valvular regurgitation.

Zhu et al. (2011) conducted an observational in adolescent idiopathic scoliosis (n=83). Thoracic curve vs. Nonthoracic curve was evaluated on Regurgitation of one or more valves. Thoracic curve in adolescent idiopathic scoliosis was associated with a 53.73% prevalence of valvular regurgitation compared to 43.75% in nonthoracic curves, with significantly higher tricuspid involvement.
