Insights
Aortic valvular calcification (AVC) severity correlates with concomitant aortic regurgitation (AR) in patients with severe aortic stenosis (AS). Increased AVC may cause or worsen AR, impacting disease progression.
Area of Science:
- Cardiology
- Radiology
- Valvular Heart Disease
Background:
- Severe aortic stenosis (AS) often coexists with aortic regurgitation (AR).
- The relationship between aortic valvular calcification (AVC) and AR severity in AS patients is not well understood.
Purpose of the Study:
- To investigate the association between AVC and the severity of concomitant AR in patients with severe AS.
Main Methods:
- Retrospective review of 95 patients with severe AS.
- Transthoracic echocardiography and multidetector computed tomography (MDCT) were performed within 1 month.
- Patients were categorized by AR severity: none/trivial (n=27), mild (n=53), and moderate (n=15).
Main Results:
- Aortic valvular calcification score (AVCS) and volume (AVCV) significantly increased with AR severity (P=0.014).
- Indexed AVCS and AVCV also showed a significant positive correlation with AR severity (P=0.004).
Conclusions:
- AR severity in severe AS patients correlates with MDCT-measured AVCS and AVCV.
- AVC may be a causative factor for concomitant AR, potentially worsening the disease condition.
Background:
Patients with severe aortic stenosis (AS) frequently have concomitant aortic regurgitation (AR), but the association between aortic valvular calcification (AVC) and the severity of AR remains unclear.
Methods And Results:
We retrospectively reviewed patients with severe AS who underwent transthoracic echocardiography and multidetector computed tomography (MDCT) within 1 month. The patients were divided into 3 groups according to the degree of concomitant AR. The association between AVC and the severity of concomitant AR was assessed in patients with severe AS. The study population consisted of 95 patients: 43 men and 52 women with a mean age of 82±7 years. Of the 95 patients with severe AS, 27 had no or trivial AR, 53 had mild AR, and 15 had moderate AR. The AVC score (AVCS) and AVC volume (AVCV) significantly increased as the severity of concomitant AR increased (P=0.014 for both), and similar findings were obtained for the AVCS and AVCV indexes (P=0.004 for both).
Conclusions:
The severity of AR correlated with AVCS and AVCV measured by MDCT in patients with severe AS. AVC may cause concomitant AR, leading to worsening of disease condition.
