These 15 patients had complete deficient posterior\u2010inferior rim of 0\u2009mm and\/or a large defect of \u226538\u2009mm. Multivariate logistic regression analysis showed that transcatheter closure failure was independently related to complete deficient posterior\u2010inferior rim and a large defect of \u226538\u2009mm. Incomplete deficient posterior\u2010inferior rim of &gt;0 to &lt;5\u2009mm was observed in 84 patients. All these patients successfully underwent transcatheter closure, except two patients with a large defect of \u226538\u2009mm. Complete deficient posterior\u2010inferior rim was observed in 37 patients. The frequency of complete deficient posterior\u2010inferior rim was higher in patients who failed transcatheter closure (87% vs. 23%, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.01), but transcatheter closure was performed successfully if the range of complete deficient rim was \u226430\u00b0.

Transcatheter closure could be performed even in patients with complete deficient posterior\u2010inferior rim if the range was partial. Our findings can help to identify candidates for transcatheter
