Bicuspid aortic valve disease was associated with significantly increased pulmonary artery stiffness compared to healthy controls (11.08 ± 2.27 vs. 7.11 ± 1.54 kHz/sec, P < 0.001).

Does bicuspid aortic valve disease impair the elastic properties of the pulmonary artery compared to healthy controls?
Patients with bicuspid aortic valve disease exhibit significantly increased pulmonary artery stiffness compared to healthy controls, suggesting that vascular elasticity impairment extends beyond the aorta.
Absolute Event Rate: 11.08% vs 7.11%

OBJECTIVE: Although the vascular complications of bicuspid aortic valve (BAV) disease cause significant morbidity and mortality, the role of pulmonary artery in this pathogenesis is less understood. We aimed to assess the elastic properties of pulmonary artery with echocardiography in patients with BAV. MATERIAL AND METHODS: Thirty patients with BAV (26 males) were enrolled in this study. The presence of aortic stenosis was accepted as exclusion criteria. Thirty-two healthy subjects (27 males) with no any history of cardiovascular disease comprised the control group. In all patients, maximal frequency shift (MFS) and acceleration time (AcT) of the pulmonary artery flow trace were measured echocardiographically in parasternal short-axis view. Subsequently, pulmonary artery stiffness (PAS) was calculated by using the following formula PAS (kHz/sec) = MFS/AcT. RESULTS: There were no significant differences in baseline demographic characteristics of the study population. Aortic strain and aortic distensibility index were lower, and aortic stiffness index (SI) higher, in patients with BAV. The PAS was significantly increased in patients with BAV compared with control subjects with tricuspid aortic valve (11.08 ± 2.27 vs. 7.11 ± 1.54, P < 0.001). There was a significant correlation between aortic diameters, aortic elasticity indexes, and PAS. Multivariate linear regression analysis, the only significant independent factor affecting the PAS was SI (β = 0.547, P < 0.001). CONCLUSION: We demonstrated that elastic properties of pulmonary artery tend to be impaired as in the aorta in patients with BAV disease.
Çeli̇k et al. (Thu,) conducted a case-control in Bicuspid Aortic Valve (n=62). Bicuspid aortic valve vs. Healthy subjects with tricuspid aortic valve was evaluated on Pulmonary artery stiffness (PAS) (p=<0.001). Bicuspid aortic valve disease was associated with significantly increased pulmonary artery stiffness compared to healthy controls (11.08 ± 2.27 vs. 7.11 ± 1.54 kHz/sec, P < 0.001).
