Abstract

Objective: To determine the prevalence of the Crochetage sign on electrocardiography and to assess its association with Doppler echocardiographic parameters and occluder device size in patients with secundum atrial septal defect (ASD) undergoing percutaneous device closure. Methods: Mixed retrospective chart review and prospective observation. Results: Ninety-six patients were included (mean age 43,39 ± 15,54 years; 80,2% female). The Crochetage sign was present in 47 cases (48,9%), after 6 months of percutaneous atrial septal defect closure, this sign disappeared in 48,94% of cases. Compared with patients without the sign, those with Crochetage had larger ASD diameter, greater right-ventricular chamber dimensions, higher TAPSE, and higher pulmonary artery pressure (all p < 0,05). Presence of the Crochetage sign was associated with an average increase in occluder size of 5,78 mm (β = 5,78; 95% CI, 3,65–7,91; p < 0,001). Conclusions: In patients with secundum ASD, the Crochetage sign is associated with—and appears predictive of—larger defect size, larger occluder device size, increased right-ventricular dimensions, higher TAPSE, and elevated pulmonary artery pressure.
