However, the association between the level of atrial septal protrusion and cerebral embolism is still unclear. The purpose of the present study was to assess the association between the maximal distance of atrial septal protrusion and cryptogenic stroke.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 588 consecutive acute ischemic stroke patients (70\u2009\u00b1\u200911 (mean\u2009\u00b1\u2009SD) years, 401 men) who underwent transesophageal echocardiography were enrolled. The maximal distance of atrial septal protrusion into the right or left atrium was measured. Atrial septal aneurysm was diagnosed when the maximal distance of atrial septal protrusion was &gt;10\u2009mm. Cryptogenic stroke was defined as non-lacunar ischemic stroke without &gt;50% proximal artery stenosis or occlusion, cardioembolic sources, \u22654\u2009mm atherosclerotic plaques in the aortic arch, or carotid or vertebral artery dissection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The rate of cryptogenic stroke increased with the increasing maximal distance of atrial septal protrusion.
