A total of 34 patients had IMH and they tended to be older (69.7 \u00b1 12.4 versus 60.5 \u00b1 16.2 years; p = 0.006). The development of pericardial effusion was more frequent in patients with IMH than in patients with AD. They were also less likely to receive surgery as compared to AD patients (26.5% versus 73.2%; p &lt; 0.0001). Overall mortality of IMH was not significantly higher than that of classic AD (29.4% versus 21.4%; p = 0.45). For IMH patients, the mortality rate with medical treatment was 32%. Ten (40%) of the 25 medically treated patients developed adverse outcomes. However, no independent predictors of adverse outcomes were identified in the study. In follow\u2010up imaging studies of 15 patients who survived IMH without surgical repair, 14 patients showed complete resolution of IMH and 1 progressed into classical AD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Acute type A IMH in Chinese patients showed a high mortality rate with medical treatment. It has a highly unpredictable course with no reliable clinical and anatomical predictors. Surgical therapy should be the treatment of choice for Chinese patients with acute IMH, especially those who are younger and have less comorbidities. \u00a9 2011 Wiley Periodicals,
