The Claim
The annual rate of ascending aorta dilation in adults with bicuspid aortic valve and no severe dysfunction is approximately 0.23 mm per year, as measured by computed tomography, and this rate is lower than previously reported rates using echocardiography.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with a bicuspid aortic valve and no severe heart dysfunction, the aorta expands by about 0.23 millimeters per year when measured with computed tomography, which is slower than earlier measurements made with echocardiography.

The annual rate of ascending aorta dilation in adults with bicuspid aortic valve and no severe dysfunction is approximately 0.23 mm per year, as measured by computed tomography, which is lower than previously reported rates using echocardiography.
Computed tomography scans show the aorta's size more precisely than ultrasound, so the true growth rate is smaller than what older ultrasound measurements suggested.
What the research says
1 studyThis study found that in people with a common heart valve issue, the main artery grows about 0.23 mm per year — slower than older estimates from ultrasound scans. It used more accurate CT scans to measure this, supporting the idea that earlier numbers were too high.
