Although successful corrective surgery of heart defects exists, there is an increased risk of morbidity and mortality in cyanotic children compared with acyanotic [ 4].
In a scenario where a true increased risk of fetal death associated with vaccination exists, an increased risk of fetal death conferred by H1N1 infection itself among unvaccinated women might have biased results towards the null.
There also exists an increased risk of thrombosis in beta-thalassemia intermedia and major, causing deep venous thrombosis, pulmonary hypertension, and pulmonary embolism, inversely correlated with the hemoglobin level [ 87].
