Is a wide QRS/T angle in bundle branch blocks associated with increased risk for coronary heart disease and all-cause mortality in the Atherosclerosis Risk in Communities ( ARIC ) Study?
A wide spatial QRS/T angle in BBB is associated with increased risk for CHD and all-cause mortality over and above the predictive value for BBB alone. The risk for women is as high as or higher than that in men.
TEE-derived Qp/Qs lacks the accuracy required to play a crucial role in quantitatively measuring the severity of residual shunt, while two-dimensional TEE can reliably detect residual leakage after VSD closure and lead to optimal judgment on the need for re-repair.
