The aim of this study was to assess whether platypnea and orthodeoxia occur in Fontan patients. We divided 14 Fontan patients into 2 groups: 8 patients who had pulmonary arteriovenous fistulas and/or intra-atrial shunts (group A) and 6 patients who had neither pulmonary arteriovenous fistulas nor intra-atrial shunts (group B). They were compared with 9 controls (group C). ⋯ All groups showed the ventilatory equivalent was significantly higher in the sitting position than in the supine position (p < 0.05 to 0.01). We demonstrated platypnea and orthodeoxia in Fontan patients with pulmonary arteriovenous fistulas and intra-atrial shunts. We believe platypnea and orthodeoxia should be regard as a complication in Fontan patients with pulmonary arteriovenous fistulas and/or intra-atrial shunts.

Syncopes appear in 10-20% in arrhythmogenic right ventricular dysplasia-cardiomyopathy (ARVD/C). In the majority of cases sustained or non-sustained monomorphic ventricular tachycardias represent the underlying mechanism of syncope. In other cases the mechanism remains unclear. ⋯ In 11 cases the mechanism of syncopes remained unclear. In patients with ARVD/C and syncopes beyond detectable or inducible monomorphic VT, several mechanisms of syncopes could be identified with conduction disease as the predominant finding. These results may help in identifying rare mechanisms of syncopes in ARVD/C.

To evaluate the predictive role of hs-CRP and fibrinogen for cardio- and cerebrovascular events in a population of patients with type 2 diabetes. ⋯ Our data show that in patients with diabetes mellitus, that in the follow-up the presence of high plasma levels of hs-CRP and fibrinogen are predictive for fatal or non fatal events.
