Data presented as n (%) for categorical data. P-value <0.05 defined as statistically significant difference between the four age groups.
Abbreviations: CHB, complete heart block; CVA, cerebral vascular accident; MI, myocardial infarction. We used standard STS definition for all complications. Operative Mortality defined as death in hospital or death within 30 days after procedure.
*:
After Bonferroni correction, p<0.005 was considered significant.
