[Show abstract][Hide abstract] ABSTRACT: Syncope and carotid sinus reactions (CSR) occur frequently in patients undergoing carotid angioplasty (CA). We investigated risk factors and the neurological consequences of carotid sinus syncope induced by CA.
We examined 359 consecutive patients. Patients underwent assessment of cerebrovascular reserve before CA and continuous electroencephalographical monitoring during the procedure. We examined the impact of vascular risk factors, cerebral hemodynamics, characteristics of plaque, and procedural modality on the incidence of CSR and syncope. The effect of syncopes on periprocedural complication rates was also investigated.
CSR and syncope occurred in 62.7% and 18.0% of the procedures, respectively. The occurrence of CSR during angioplasty was significantly associated with the appearance of syncope. The incidence of syncope was significantly higher in longer plaques located in the carotid bifurcation, in the presence of contralateral carotid stenosis, or when protection devices were used. Although TIA during CA was more common in syncopal patients, stroke or death rates were similar in the 2 groups.
Syncope occurs more frequently in patients with long plaques proximal to the carotid bifurcation, but it does not increase the periprocedural complications rate.
[Show abstract][Hide abstract] ABSTRACT: Coronary artery fistulas are one of the most common congenital anomalies of the coronary arteries. Most fistulas are small and of no clinical significance, although larger or multiple fistulas can be symptomatic and produce complications. Early percutaneous occlusion is now always recommended, and surgical closure is restricted to use for multiple or large fistulas. Here we report four cases of coronary fistula draining from the coronary arteries to the pulmonary vascular bed, which were treated with percutaneous occlusion by coils.

Las fístulas coronarias suelen ser pequeñas y sin significación clínica, pero las más grandes pueden causar síntomas y llegar a producir complicaciones. Actualmente, se recomienda siempre su cierre temprano percutáneo, reservando la cirugía para las fístulas múltiples o de gran tamaño. Presentamos 4 casos de fístulas coronarias que drenaban en el territorio vascular pulmonar tratadas mediante oclusión percutánea con coils

[Show abstract][Hide abstract] ABSTRACT: We report the case of a 3 year old girl with a congenital right coronary artery-right ventricle fistula demonstrated by two dimensional echocardiography with color-flow Doppler and cardiac catheterization and angiography.
The treatment was percutaneous transcatheter embolization by two detachable coils (7 mm × 20 cm and 6 mm × 20 cm) with successful complete occlusion. There were no complications.
