[Tetralogy of Fallot complicated by severe hemoptysis in the adult]. / Tetralogía de Fallot en el adulto complicada con hemoptisis grave. Tratamiento mediante embolización de la arteria tirocervical izquierda.

Fallot tetralogy with pulmonary artery atresia is a special situation in which the patient can survive up to middle-age. In these cases some complications such as hemoptysis can appear with difficult treatment that endangers the life of the patient. When the cause of bleeding is the arteriovenous shunts, which are frequent in the multiple vascular malformations originated in this congenital cardiopathy, the selective embolization of these malformations can be an effective option of treatment.

[Impact of diabetes mellitus on the late clinical outcome of coronary revascularization with stents]. / Influencia de la diabetes mellitus en los resultados clínicos tardíos de la revascularización coronaria con stents.

INTRODUCTION: The Influence of diabetes mellitus in the late outcome of coronary stenting remains controversial. AIM: The aim of this study was to determine the late clinical outcome of diabetics in comparison with non diabetics and to establish whether there are subgroups of diabetic patients with a greater need for target lesion revascularization. METHODS: Two hundred sixteen consecutive patients (74 diabetics; 95 stents in 90 lesions and 142 non diabetics) who had successfully undergone coronary stenting were included in the study and followed over 17.6 +/- 10 months. The clinical events evaluated were target lesion revascularization, death and acute myocardial infarction. Independent predictive variables of target lesion revascularization were studied in both groups of patients. RESULTS: The diabetic patients presented greater cardiovascular mortality (6.7% vs 1.4%; p=0.02) but the incidence of infarction was similar in the two groups (2.7% vs. 3.5%; p=0.6). The accumulated rate of target lesion revascularization at two years was 18.2% in diabetics vs 13.3% in non diabetics (p=0.09), respectively. The presence of three vessel disease (p=0.014), history of arterial hypertension ([=0.011) and residual stenosis > 0% (p=0.005) were specific predictive factors of target lesion revascularization for diabetic patients and together with vessel diameter < 3mm (p<0.001) subgroups of diabetics were independently selected with a significantly greater incidence of target lesion revascularization than the non diabetic patients. CONCLUSIONS: Following coronary stenting, diabetic patients show a greater cardiovascular mortality than non diabetics, but only some subgroups of diabetics (small vessels extensive coronary disease, associated arterial hypertension, residual stenosis) show a significantly greater risk of target lesion revascularization.
