Key result
Bicuspid aortic valves are linked to ~36% higher rates of moderate-to-severe calcification vs tricuspid.
Why the study?
Bicuspid aortic valves are thought to accelerate aortic valve calcification compared to tricuspid valves, but comparative CT data are limited.
Does bicuspid aortic valve morphology increase the burden of aortic valve calcification compared to tricuspid aortic valves in patients undergoing cardiac CT?
Observational (n=61)
No
Does bicuspid aortic valve morphology increase the burden of aortic valve calcification compared to tricuspid aortic valves in patients undergoing cardiac CT?
Absolute Event Rate: 51.9% vs 38.2%
Bicuspid aortic valves are associated with a higher calcific burden than tricuspid valves on CT, though calcification alone does not perfectly predict hemodynamic stenosis.
Introduction: One known cause of left ventricular outflow blockage and a significant predictor of cardiovascular risk is calcification of the aortic valve leaflets. Despite making up only 1-2 percent of the general population, bicuspid aortic valves (BAV) are thought to accelerate mineral deposition due to their altered design. This review compares the burden and distribution of aortic valve calcification (AVC) in patients with bicuspid versus tricuspid valves through the inclusion of computed-tomography outcomes of a recent single-center study. Materials and Methods: A retrospective analysis was conducted on sixty-one persons who were referred for cardiac CT scans between July and September of 2024. Using Multiplanar reconstructions, valve morphology was categorized, and the Agatston method was used to measure calcium volume. Clinical information was taken out of electronic medical records and examined using SPSS 22.0. Results: In 65.6% of cases, the cohort (mean age 54.6 ± 12.3 years, 57% male) demonstrated symptoms indicative of AVC. Compared to 38.2% of individuals with tricuspid valves (TAV), half (51.9%) of BAV patients had moderate-to-severe calcification. Higher calcium scores were positively correlated with both hypertension and tobacco use (p < 0.01). Angaston grade and CT markers of hemodynamically grave stenosis did not precisely link. Conclusions: Compared to its tricuspid cousin, BAV shape has a detectable higher calcific burden; however, luminal blockage cannot be anticipated only by calcification. Planning a surgical or Tran’s catheter execution still requires multipara metric appraisal.

Shahzadi et al. (2025) conducted an observational in Aortic valve calcification (n=61). Bicuspid aortic valves vs. Tricuspid aortic valves was evaluated on Moderate-to-severe calcification. Bicuspid aortic valves were associated with a higher rate of moderate-to-severe calcification compared to tricuspid aortic valves (51.9% vs 38.2%).
