Kaplan Meir survival curve for the mortality rate in patients with and without prior chest radiation therapy. Reduced survival in CXRT group with elevated LAA volume of more than 21.9 ml compared to those with LAA volume of less than 21.9 ml adjusted to 40% of the cardiac cycle. The red line denotes patients without prior chest radiation therapy (non-CXRT group) and blue line denotes patients with prior chest radiation therapy (CXRT group)
