Abstract

OBJECTIVE: Variations in coronary anatomy, like absent left main stem and left dominant coronary system, have been described in patients with Turner syndrome (TS) and in patients with bicuspid aortic valves (BAV). It is unknown whether coronary variations in TS are related to BAV and to specific BAV subtypes. AIM: To compare coronary anatomy in patients with TS with/without BAV versus isolated BAV and to study BAV morphology subtypes in these groups. METHODS: Coronary anatomy and BAV morphology were studied in 86 patients with TS (20 TS-BAV, 66 TS-tricuspid aortic valve) and 86 patients with isolated BAV (37±13 years vs 42±15 years, respectively) by CT. RESULTS: There was no significant difference in coronary dominance between patients with TS with and without BAV (25% vs 21%, p=0.933). BAVs with fusion of right and left coronary leaflets (RL BAV) without raphe showed a high prevalence of left coronary dominance in both TS-BAV and isolated BAV (both 38%). Absent left main stem was more often seen in TS-BAV as compared with isolated BAV (10% vs 0%). All patients with TS-BAV with absent left main stem had RL BAV without raphe. CONCLUSION: The equal distribution of left dominance in RL BAV without raphe in TS-BAV and isolated BAV suggests that presence of left dominance is a feature of BAVs without raphe, independent of TS. Both TS and RL BAV without raphe seem independently associated with absent left main stems. Awareness of the higher incidence of particularly absent left main stems is important to avoid complications during hypothermic perfusion.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
