Methods and Materials
Retrospective evaluation of patients who underwent cardiac CT prior to PPVI and didn’t experience coronary artery compression during the angiographic procedure.
Using double oblique reconstructed images,
the minimal distances between each coronary artery (right coronary artery - RCA,
left main - LM,
left descending artery - LAD,
left circumflex - LCx) and the stenotic part of the pulmonary trunk/conduit (or the site of the future valve implantation) were measured (Fig.
In cases with both diastolic and systolic phases available the pulmonary trunk diameters were assessed for both phases at the intended level for the future valve implantation.
For patients who had both systolic and diastolic phases available double measurements were performed (Fig.
absolute difference between the two phases was calculated and the differences between the two cardiac phases were compared using the Wilcoxon signed-rank test.
