Of those who had AF, mean age was 66.9 years; 54% were female, and 83% had paroxysmal AF.

Thromboembolic events occurred in 196 (15%) patients, most commonly stroke (11%), followed by pulmonary embolism (4%) and deep venous thrombosis (4%). Bleeding events occurred in 313 patients (24%), most commonly hematuria (12%), gastrointestinal bleed (11%), epistaxis (5%), and intracranial hemorrhage (1%). Seventy\u2010two patients (6%) underwent the Nuss procedure and were younger (45.3\u00a0vs. 68.2 years,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.001), predominantly male (65%), and had lower risk scores compared to the non\u2010Nuss cohort. Patients who underwent the Nuss procedure had significantly fewer bleeding events (5.6%\u00a0vs. 25%,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.001) with similar thromboembolic rates. The pectus severity index, available in the 370 patients who underwent dedicated radiologic review, was not associated with bleeding (adjusted OR 0.89, 95% CI 0.75\u20131.05). The difference in bleeding by surgical status persisted after multivariable adjustment (adjusted OR 0.28, 95% CI 0.10\u20130.79) and after propensity score matching (5.6%\u00a0vs. 16.7%,\n                      <jats:italic>p<\/jats:italic>\n                      = 0.030).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>AF was identified in approximately one in nine patients within this single\u2010institution cohort of adults with PE, with paroxysmal AF representing the predominant subtype. Patients who had undergone surgical repair demonstrated a lower incidence of bleeding events than anticipated based on their baseline risk profile; however, given the limited number of events observed, this finding should be interpreted with caution and requires validation in larger studies. In the absence of a non\u2013PE comparator group, these data are insufficient to determine whether PE independently confers an elevated risk of AF, and prospective, controlled investigations are necessary to elucidate this relationship.<\/jats:p>\n
