Introduction:

An increasing number of women with congenital heart disease (CHD) are surviving to adulthood and the number of pregnancies in these women is on the rise. The hemodynamic burden imposed by pregnancy places these women at risk for cardiovascular complications including congestive heart failure and arrhythmias. A number of risk stratification scores have been developed but many are based on subjective criteria such as New York Heart Association (NYHA) functional class [13]. In patients with acquired heart disease, cardiopulmonary exercise testing with measures of maximal oxygen consumption heart rate response is an excellent predictor of clinical outcomes. Chronotropic response during exercise testing predicts mortality in patients with CHD [4]. However, its predictive value for p ...
