Atorvastatin Effect on Aortic Dilatation and Valvular Calcification Progression in Bicuspid Aortic Valve (BICATOR): A Randomized Clinical Trial
Authors' conclusion
Among patients with bicuspid aortic valve without severe valvular dysfunction, atorvastatin treatment was not effective in reducing the progression of ascending aorta dilation and aortic valve calcification during 3 years of treatment despite a significant reduction in low-density lipoprotein cholesterol levels.
Study context
- Population
- Adults with bicuspid aortic valve, nonsevere valvular dysfunction and calcification, ascending aorta diameter ≤50 mm192 completed 36 months
- Participants
- 220 adults
- Comparison
- Atorvastatin vs placebo
- Primary endpoint
- Growth of maximum ascending aorta diameter
- Follow-up
- 3 years
Methodological detailsplacebo-controlled, 28 patients (12.7%) discontinued treatment (15 on atorvastatin, 13 on placebo)
- Placebo-controlled
- 28 patients (12.7%) discontinued treatment (15 on atorvastatin, 13 on placebo)
Primary result
As reported in the abstract
Increase in maximum ascending aorta diameter
P = 0.613
Further findings
Median, mg/dL
| Outcome | Atorvastatin | Placebo | P value |
|---|---|---|---|
| Change in LDL-C | −30 (IQR −51.65 to −1.75 mg/dL) | 6 (IQR −4, 22.5 mg/dL) | P < 0.001 |
Progression of aortic valve calcium score
- No significant difference between groups
- P = 0.167
Valvular dysfunction
- No significant difference between groups
