WebThe crochetage pattern was present in at least 1 inferior limb lead in 10 of 28 PFO patients (36%) and 3 of 32 control subjects (9%) (P<0.05). The sensitivity and specificity of the crochetage pattern for diagnosis of PFO in cryptogenic stroke cases were 36% and 91%, respectively; positive predictive value was 77%.

Webcrochetage pattern remains unknown. Interestingly, within 10 to 15 days of ASD repair, the majority (53%) of pa-tients with a crochetage pattern in at least 1 inferior leads have resolution of this ECG finding.2 The crochetage pat-tern (marked by red arrows in Figure 2) added both sen-sitivity and specificity to the ASD diagnosis in this case. WebThe first published study describing crochetage found the pattern in 73% of patients with ASD. 2 Its presence on ECG positively correlates with the severity of the left-to-right shunt and shunt size. 1 The sensitivity and specificity of this sign for a secundum ASD progressively increase with the number of inferior leads involved.
